Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to operating system switching methods, devices, electronic devices, media, and program products. Background Technology

[0002] With the development of smart devices, more and more electronic devices, such as laptops and cloud-based products, can simultaneously install two operating systems. For example, two operating systems can be installed on a single hard drive, sharing all the device's hardware resources. They can also install two operating systems of the same type but different versions. However, in these technologies, switching between dual systems requires restarting the system and pressing the corresponding key to enter the boot menu in the BIOS (Basic Input Output System), and then selecting the corresponding system. Similarly, when installing two operating systems of the same type but different versions, a restart and selection of the desired system are also required to correctly boot into the user's desired system.

[0003] Such switching methods are cumbersome and lack interoperability between different systems, failing to reflect the overall characteristics of the device and requiring repetitive setup operations across different systems. Some related technologies allow installing two systems on different hardware, switching between dual systems by changing different input sources, with both systems constantly running. However, this solution cannot share hardware between different systems, and since both systems are always running, even when one is not in use, it wastes resources. Summary of the Invention

[0013] In some alternative implementations, before receiving the system switching command from the user, the method further includes: In response to a switching operation triggered by a preset key, a system switching interface is displayed in the graphical user interface; the system switching interface includes identifiers corresponding to each operating system. In response to the selection operation of the operating system in the system switching interface, the selected operating system is used as the second operating system, and the system switching instruction is generated.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] As an optional application scenario of this invention, such as Figure 1 As shown, application 101 is installed in terminal device 110, and user 130 can interact with application 101 through terminal device 110 and / or access device of terminal device 110.

[0026] For example, application 101 can be any application that provides system switching services. Figure 1 In the application scenario shown, if application 101 is active, the terminal device 110 can display the interface 102 of application 101.

[0027] Terminal device 110 may be a mobile terminal, a fixed terminal, or a portable terminal, etc., including but not limited to desktop computers, laptop computers, multimedia tablets, or any combination thereof, including accessories and peripherals of these devices or any combination thereof. In some embodiments, terminal device 110 may also support any type of interface.

[0028] It should be noted that, Figure 1 This is merely an example of an application scenario and does not limit the scope of protection of this invention.

[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the pages shown in the drawings are merely examples, and various page designs are possible in practice. The various graphic elements on the page may have different arrangements and different visual representations, one or more elements may be omitted or replaced, and one or more other elements may also be present; no limitations are imposed in the embodiments of the present invention. Furthermore, the embodiments described below primarily pertain to the terminal device 110.

[0030] This invention provides an operating system switching method that directly displays a graphical user interface for switching operating systems to the user by listening for hotkeys in the operating system. This allows users to quickly switch operating systems without entering the BIOS, solving the problem of complex operating system switching processes in related technologies. Furthermore, storing common data in a shared storage space allows for the sharing of common attributes, resolving the issue of needing to perform repetitive setting operations across different systems.

[0031] According to an embodiment of the present invention, an embodiment of an operating system switching method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] This embodiment provides an operating system switching method, which can be used in the aforementioned terminal devices, such as desktop computers, portable computers, tablet computers, etc. Figure 2 This is a flowchart of an operating system switching method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: If the first operating system is currently running, receive a system switching instruction for switching the operating system to the second operating system.

[0033] It is understood that the computer or other terminal device to which this embodiment is applied needs to have at least two operating systems installed; otherwise, switching between operating systems is not possible with a single operating system. For ease of description, the operating system currently running on the terminal device will be referred to as the first operating system, and the operating system targeted by the user for operating system switching will be referred to as the second operating system. If the current terminal device has three or more operating systems, the user can specify the target operating system, that is, the user can specify which specific operating system is the second operating system. The operating system can include Windows operating system and its various versions, such as Windows 8, Windows 11, Windows Server, etc., and can also include Android operating system and its various versions, as well as macOS operating system and its various versions. When an operating system switch is required, a system switch instruction needs to be generated to switch the current operating system to the corresponding second operating system (i.e., the target operating system), at which point the first operating system can receive the instruction.

[0034] Step S202: Obtain the current boot order list. The boot order list includes boot entries corresponding to the operating system.

[0035] Upon receiving a system switch command, the boot order can be adjusted accordingly. The boot order is the order in which available operating systems are checked during terminal device startup (e.g., the order of Windows, Android, or macOS). Normally, the terminal device will attempt to boot from the operating systems in the boot order sequentially until a usable one is found. Therefore, placing the second operating system first in the boot order ensures that the terminal device boots into the second operating system.

[0036] When adjusting the boot order, the current boot order list needs to be obtained first. For example, in Windows operating systems, this can be obtained by reading the BootOrder variable. This can be done by calling the UEFI runtime service function, specifically the GetFirmwareEnvironmentVariableExW function in Windows, and passing BootOrder as the variable name. The boot order list includes the boot entry corresponding to the operating system, and may also include the device names corresponding to each operating system, such as hard drive or USB flash drive names. Since modifying the BootOrder variable requires high system privileges, the operating system switching process in this embodiment needs to have the corresponding permissions, such as the SeSystemEnvironmentPrivilege permission that allows read and write operations on firmware environment variables.

[0037] Step S203: According to the system switching instruction, the boot entry corresponding to the second operating system is adjusted to the first position in the boot order list.

[0038] Upon receiving a system switch command, the boot order needs to be adjusted accordingly. In this embodiment, the boot order can be adjusted by modifying the boot order list. As mentioned earlier, boot items in the boot order list have priority, or the devices are attempted to boot sequentially according to the order in the boot order list. In this case, the boot entry corresponding to the second operating system is moved to the first position in the boot order, achieving the effect of entering the second operating system when the terminal device boots. Under the Android operating system, the priority of the boot entry corresponding to the second operating system can also be increased. For example, the command `sudoefibootmgr -o 000A,0002,0005` can be used to move the priority of boot entry number 000A to the first position, ensuring that the operating system corresponding to boot entry number 000A is booted first when the terminal device boots.

[0039] Step S204: Reboot the terminal device to start the second operating system according to the adjusted boot order.

[0040] Since the boot order settings are stored in the terminal device's firmware, such as UEFI (Unified Extensible Firmware Interface) firmware or BIOS firmware, and the boot order only takes effect when the terminal device starts up, after obtaining the adjusted boot order, a reboot can make the adjusted boot order take effect, thereby allowing the terminal device to automatically enter the second operating system without requiring the user to enter the BIOS to make adjustments.

[0041] The operating system switching method provided in this embodiment allows switching between different operating systems, solving the problem of needing to enter the BIOS to switch in related technologies, improving convenience and reducing learning costs. Furthermore, since multiple operating systems are installed and switched on the same terminal device, there is no need for multiple terminal devices to switch operating systems using different input sources, reducing the waste of computing resources and energy, and eliminating the problem of not being able to share hardware between different systems found in related technologies.

[0042] This embodiment provides an operating system switching method, which can be used in the aforementioned terminal devices, such as desktop computers, portable computers, tablet computers, etc. Figure 3 This is a flowchart of an operating system switching method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: If the first operating system is currently running, receive a system switching instruction for switching the operating system to the second operating system.

[0043] Please see details Figure 2 Step S201 of the illustrated embodiment will not be described again here.

[0044] Step S302: Obtain the current boot order list. The boot order list includes boot entries corresponding to the operating system.

[0045] Please see details Figure 2 Step S202 of the illustrated embodiment will not be described again here.

[0046] In some alternative implementations, step S302, “obtaining the current boot order list,” includes step a1.

[0047] Step a1: Obtain all boot items in the boot order using the boot order management tool to obtain a boot order list containing each boot item.

[0048] When obtaining the boot order list, you can use the boot order management tool built into the first operating system, such as the efibootmgr tool, to manage the boot entries in the UEFI firmware. For example, you can use the command `sudoefibootmgr` to list all boot entries (i.e., the boot order list), which will contain information about each boot entry. Boot entry information may include BootCurrent, BootOrder, etc., where BootCurrent is the boot entry number used for this boot (e.g., 0002), and BootOrder is the boot order list arranged by priority (e.g., 0002, 000A, 0003). Each boot entry has a boot entry description, such as Windows Boot Manager (Windows operating system) or Ubuntu (Linux operating system). For example, if the first operating system is an Android or Linux operating system (for simplicity, we will use Android as an example below), this step can be performed.

[0049] Step S303: According to the system switching instruction, the boot entry corresponding to the second operating system is adjusted to the first position in the boot order list.

[0050] Please see details Figure 2 Step S203 of the illustrated embodiment will not be described again here.

[0051] In some optional implementations, step S303, "according to the system switching instruction, adjusting the boot entry corresponding to the second operating system to the first position in the boot order list", includes steps S3031 to S3034.

[0052] Step S3031: Parse the boot order list to obtain the boot descriptor corresponding to each boot item in the boot order list.

[0053] Step S3032: Parse each boot descriptor to determine the description string corresponding to each boot item.

[0054] Step S3033: Determine the target boot entry corresponding to the second operating system based on the description string corresponding to each boot entry.

[0055] Step S3034: Adjust the target boot entry to the first position in the boot order list.

[0056] When modifying the boot order list under an operating system, the boot order list needs to be parsed first. As mentioned earlier, in Windows, the boot order list is stored in the `BootOrder` variable, where each two bytes constitute a Little-Endian format boot entry number. Parsing these boot entry numbers, for example by calling the `GetFirmwareEnvironmentVariableExW` function, allows you to obtain detailed data for each boot entry, i.e., the boot descriptor. However, the boot descriptor's structure is relatively complex and cannot be matched directly with the user's selected second operating system. Therefore, further parsing of the boot descriptor is necessary to determine the description string corresponding to each boot entry, such as Windows Boot Manager or Ubuntu.

[0057] After obtaining the description strings corresponding to each boot entry, the description strings corresponding to the boot entries can be matched with the target system identifier stored in the system switching instruction, such as Windows Boot Manager under the Windows operating system, to obtain the target boot entry corresponding to the second operating system. Then, the target boot entry is adjusted to the first position in the boot order list to update the boot order list.

[0058] In some alternative implementations, step S3034, "adjusting the target bootstrap to the first position in the bootstrap order list," includes steps b1 and b2.

[0059] Step b1: Delete the target boot entry corresponding to the second operating system from the boot order list to obtain the intermediate order list.

[0060] Step b2: Add the target guide item to the first position in the intermediate order list to obtain the adjusted guide order list.

[0061] During the adjustment of the boot order list, the target boot entry corresponding to the second operating system can be removed from the original boot order list. Then, the other boot entries in the original boot order list are arranged in order to obtain an intermediate order list. At this time, the intermediate order list does not include the target boot entry.

[0062] After obtaining the intermediate order list, insert the target boot entry into the first position of the intermediate order list, and shift the other boot entries to the next position in turn to obtain the adjusted boot order list. This adjusted boot order list can then be stored as the boot order list. For example, in the Windows operating system, the boot order list can be stored in the BootOrder variable. Figure 4This is a system switching flowchart under a Windows operating system according to this embodiment, such as... Figure 4 As shown, under the Windows operating system, the first step is to check if the process has the corresponding permissions. For example, you can check if the current terminal device firmware is in UEFI boot mode and if it is running with administrator privileges. If permissions are granted, the boot order can be obtained, i.e., the current boot order list can be retrieved. This can be done using the `GetFirmwareEnvironmentVariableExW` function, passing `BootOrder` as the variable name to obtain the boot order list. Then, the `GetFirmwareEnvironmentVariableExW` function is used again, passing `Boot1`, `Boot2` (i.e., the first and second boot items in the boot order list) as parameters to obtain boot item information, including the boot item sequence number and descriptor. At this point, it is necessary to determine the boot order based on the second operating system (e.g., ...). Figure 4 The process involves adjusting the boot order list for MegaOS, then using the service function SetFirmwareEnvironmentVariableExW to write the new boot order list into the BootOrder variable and setting the corresponding variable attributes (such as NON_VOLATILE). Once the boot order list is set and effective, the system can switch to the MegaOS operating system normally after rebooting.

[0063] In some optional implementations, the operating system switching method provided in this embodiment further includes steps c1 to c3.

[0064] Step c1: Create a shared storage space for the first and second operating systems.

[0065] Step c2: After receiving the system switch command, generate a corresponding configuration file based on the current configuration parameters of the terminal device and store it in the public storage space. The configuration file includes configuration parameters that need to be kept consistent after switching operating systems.

[0066] Step c3: After starting the second operating system, configure the terminal device parameters according to the configuration file in the public storage space.

[0067] In some cases, related technologies cannot retain public data after switching operating systems. For example, device names, software activation codes, screen mode data, current brightness values, current volume values, Wi-Fi hotspot names and passwords for the same device on different systems require reconfiguration after the operating system switch. In this embodiment, a public storage space can be created to store this public data. This data is retained after the system switch without requiring the reconfiguration of various parameters, improving the user experience. For example, a separate hard drive partition (e.g., a FAT32 partition) can be used as the public storage space, or a directory within that partition can also be used. Upon receiving the system switch command, a configuration file is generated based on the terminal device's current configuration parameters, such as screen mode data, current brightness values, current volume values, Wi-Fi hotspot names and passwords. In this embodiment, the configuration file can be a JSON (JavaScript Object Notation) file, an Excel file, or a text file. This file is used by the second operating system to configure various parameters of the terminal device based on this configuration file stored in the public storage space after the second operating system starts, ensuring that the device's configuration remains consistent after the operating system switch.

[0068] In some alternative implementations, the method further includes step c4.

[0069] Step c4: If the drive letter corresponding to the public storage space has not been hidden or deleted, hide or delete the drive letter corresponding to the public storage space in the file manager.

[0070] To prevent configuration files in the shared storage space from being modified manually and to avoid data synchronization issues when switching systems, the shared storage space needs to be hidden. If the drive letter corresponding to the shared storage space is not hidden or deleted, it can be hidden or deleted in the file manager. For example, if the primary operating system is Windows, the drive letter to be hidden can be identified by setting the NoDrives registry key. In this case, the shared storage space will be inaccessible in the file manager, but disk data can still be accessed through the drive letter. Alternatively, the shared partition drive letter can be deleted, for example, by automatically executing cmd or PowerShell commands.

[0071] In some alternative implementations, step c3, "configuring the terminal device according to the configuration file in the public storage space," includes steps c31 and c32.

[0072] Step c31: If the drive letter corresponding to the public storage space is hidden or deleted, allocate and display the drive letter for the public storage space.

[0073] Step c32: Configure parameters according to the configuration file in the public storage space.

[0074] For data security reasons, the drive letter corresponding to the public storage space may sometimes be hidden or deleted. In such cases, if you want to configure terminal device parameters based on the configuration files in the public storage space, you need to first assign and display a drive letter to the public storage space to ensure its readability and writability. For example, if the secondary operating system is Windows, you can automatically assign and display the corresponding drive letter by executing cmd or PowerShell commands. Once the public storage space has a corresponding drive letter, you can configure parameters according to the configuration files, such as screen mode data, current brightness value, current volume value, Wi-Fi hotspot name, and password.

[0075] Figure 5 This is a flowchart illustrating the activation process of a configuration file according to this embodiment, such as... Figure 5 As shown, the terminal device has two operating systems: Windows and Android. Currently, it's running Windows, meaning the primary system is Windows. Upon receiving the system switch command, on the Windows side, the drive letter needs to be hidden in the file explorer, and public data needs to be written to the public storage space in JSON format. The JSON file can be named HasGotoAndroid. Then, the drive letter is deleted using the Diskpart command. Switching the boot entry will then allow entry into the Android operating system. In the Android operating system, the JSON file in the public storage space is read with root privileges, and the terminal device parameters are set accordingly. After modifying parameters such as brightness and name, the corresponding JSON file in the public storage space is stored. This JSON file can be named HasGotoWindows.

[0076] After switching to the Windows operating system, the Windows operating system needs to check if there is a configuration file HasGotoWindows. If not, the system runs normally. If it does, the Diskpart command needs to be called to assign drive letters and read the parameters from the JSON file to apply to the parameter settings.

[0077] In some optional implementations, the operating system switching method provided in this embodiment further includes steps d1 and d2 before receiving a system switching command from a user: Step d1: In response to a switching operation triggered by a preset key, the system switching interface is displayed in the graphical user interface. The system switching interface includes icons corresponding to each operating system.

[0078] Step d2: In response to the operating system selection operation in the system switching interface, the selected operating system is used as the second operating system, and a system switching instruction is generated.

[0079] To enhance the user's graphical experience, a system switching interface can be opened via a preset key. This preset key can be a key combination, such as Ctrl+Alt+F1, or a specific key for switching systems. By using the Control Center application to listen for keyboard events, the system switching interface can pop up when the user presses the key combination or the specific key. For example, in Windows operating systems, this can be achieved by using the `windowsService` service as a persistent background process and listening for global keyboard events using `SetWindowsHookEx`. The system switching interface includes identifiers for each operating system, such as the operating system name or system descriptor. Users can select the operating system they want to switch to (i.e., the second operating system) in the system switching interface, at which point a corresponding system switching command can be generated based on the second operating system.

[0080] Step S304: Reboot the terminal device to start the second operating system according to the adjusted boot order.

[0081] Please see details Figure 2 Step S204 of the illustrated embodiment will not be described again here.

[0082] The operating system switching method provided in this embodiment allows switching between different systems, solving the problem of needing to enter the BIOS to switch in related technologies, improving convenience and reducing learning costs. It also enhances the correlation between different systems by sharing common data, reflecting the overall attributes of the device, and eliminating the need to readjust various parameters after system switching. Furthermore, since multiple operating systems are installed and switched on the same terminal device, there is no need for multiple terminal devices to switch operating systems using different input sources, reducing the waste of computing resources and energy, and solving the problem of not being able to share hardware between different systems in related technologies.

[0083] This embodiment also provides an operating system switching device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0092] In some optional implementations, the list adjustment unit includes: The boot entry deletion subunit is used to delete the target boot entry corresponding to the second operating system from the boot order list to obtain the intermediate order list.

[0093] The guide item adds a sub-unit, which is used to add the target guide item as the first item in the intermediate order list, thus obtaining the adjusted guide order list.

[0094] In some alternative implementations, the list retrieval module 602 includes: The boot item acquisition unit is used to obtain all boot items in the boot order through the boot order management tool, and obtain a boot order list containing each boot item.

[0096] The configuration file generation module is used to generate a corresponding configuration file based on the current configuration parameters of the terminal device after receiving the system switch command, and store it in the public storage space.
