[0025] Figure 2 FIG. 2 shows a block diagram of a computing device 200 according to an exemplary embodiment of the present invention. Figure 2 As shown, in a basic configuration 202, computing device 200 typically includes a system memory 206 and one or more processors 204. A memory bus 208 may be used for communication between processor 204 and system memory 206.

[0026] Depending on the desired configuration, the processor 204 can be any type of processor, including but not limited to: a microprocessor (μP), a microcontroller (μC), a digital information processor (DSP), or any combination thereof. The processor 204 can include one or more levels of cache such as a primary cache 210 and a secondary cache 212, a processor core 214, and registers 216. An example processor core 214 can include an arithmetic logic unit (ALU), a floating point unit (FPU), a digital signal processing core (DSP core), or any combination thereof. An example memory controller 218 can be used with the processor 204, or in some implementations, the memory controller 218 can be an internal part of the processor 204.

[0027] Depending on the desired configuration, the system memory 206 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. The system memory 206 may include an operating system 220, one or more programs 222, and program data 228. In some embodiments, the program 222 may be arranged to be executed by one or more processors 204 on the operating system using the program data 228 to execute the instructions 223 of the method 300 according to the present invention.

[0028] The computing device 200 may also include a storage interface bus 234. The storage interface bus 234 enables communication from storage devices 232 (e.g., removable storage 236 and non-removable storage 238) to the basic configuration 202 via the bus / interface controller 230. At least a portion of the operating system 220, the application 222, and the data 224 may be stored on the removable storage 236 and / or the non-removable storage 238, and when the computing device 200 is powered on or the application 222 is to be executed, it is loaded into the system memory 206 via the storage interface bus 234 and executed by the one or more processors 204.

[0029] The computing device 200 may also include an interface bus 240 that facilitates communication from various interface devices (e.g., output devices 242, peripheral interfaces 244, and communication devices 246) to the basic configuration 202 via the bus / interface controller 230. Example output devices 242 include a graphics processing unit 248 and an audio processing unit 250.

Example communication devices 246 may include a network controller 260, which may be arranged to communicate with one or more other computing devices 262 via a network communication link via one or more communication ports 264.

[0030] A network communication link can be an example of a communication medium. Communication media can generally be embodied as computer-readable instructions, data structures, program modules in a modulated data signal such as a carrier wave or other transmission mechanism, and can include any information delivery medium. A "modulated data signal" can be a signal in which one or more of its data sets or its changes can be carried out in a manner that encodes information in the signal. As non-limiting examples, communication media can include wired media such as a wired network or a dedicated line network, and various wireless media such as sound, radio frequency (RF), microwave, infrared (IR) or other wireless media. The term computer-readable medium used herein can include both storage media and communication media.

[0031] In the computing device 200 according to the present invention, the application 222 includes multiple program instructions for executing the multi-system installation method 300. These program instructions can instruct the processor 204 to execute some steps in the multi-system installation method 300 running in the computing device 200 of the present invention, so that various parts in the computing device 200 can install multiple operating systems by executing the multi-system installation method 300 of the present invention.

[0032] The computing device 200 can be implemented as a server, such as a file server 240, a database 250, a server, an application server, etc. These electronic devices can be such as personal digital assistants (PDAs), wireless network browsing devices, application-specific devices, or hybrid devices that can include any of the above functions. It can be implemented as a personal computer including desktop computers and notebook computer configurations. In some embodiments, the computing device 200 is configured to perform the multi-system installation method 300.

[0033] The following will explain in detail how to install the Figure 1 Multiple operating systems shown. Figure 3 FIG. 2 is a flow chart of a multi-system installation method 300 according to an exemplary embodiment of the present invention. The method 300 is suitable for execution in a computing device 200. Figure 3 As shown, the multi-system installation method 300 begins at step S310, where a disk topology file of a memory is obtained under a first operating system. In order to run the first operating system and the second operating system at the same time, and run the first operating system in the second operating system, the first operating system is first pre-installed in the computing device. The present invention does not limit the types of the first operating system and the second operating system, and can be implemented as a Windows system, a Linux system, etc.

[0034] When the first operating system is running, the computing device may receive an instruction from the user to install multiple operating systems. After receiving the instruction from the user to install multiple operating systems, the computing device obtains the disk topology file in the memory. The disk topology file is the location information of the virtual disk file actually stored on the physical disk. For example, the original file windows.doc in the C drive is stored in a certain sector of a certain disk surface on the physical disk. The disk topology file includes the system partition and file information of the first operating system in the memory. The memory can be divided into multiple partitions, and the system partition of the first operating system in the memory indicates that the first operating system is stored and runs in the system partition. The file information is the location information of the system files and user files of the first operating system stored in the disk under the first operating system, and the corresponding files can be obtained from the memory based on the location information. The file information also includes a file system identifier, which is the file system used to store the system files and user files under the first operating system. The file system identifier includes NTFS, etc.

[0035] Subsequently, step S320 is executed to generate a storage configuration file of the first operating system according to the disk topology file and write it into the memory. According to the system partition and file information in the disk topology file, the boot partition and file system identifier of the first operating system are determined. According to the boot partition and file system identifier, a storage configuration file of the first operating system is generated. The storage configuration file facilitates reading corresponding files to run the first operating system in the virtual operating environment of the second operating system.

[0036] According to an embodiment of the present invention, the first operating system is a Windows system and the second operating system is a Linux system. When the Windows system is installed on the computer, after receiving the user's instruction to install multiple operating systems, the system obtains the disk topology file from the memory, and generates a storage configuration file of the Windows system according to the disk topology file, so as to facilitate the subsequent operation of the first operating system.

[0037] Subsequently, step S330 is executed to establish an installation environment for the operating system, and the second operating system is installed under the installation environment. When installing the second operating system, it cannot be installed under the first operating system. Therefore, it is necessary to exit the first operating system and start the BIOS (Basic Input Output System) system of the computing device. The BIOS system is a set of programs solidified on a ROM chip on the motherboard of the computer. It stores the most important basic input and output programs of the computer, the self-test program after power-on, and the system self-starting program. It can read and write specific information of the system settings from CMOS. Under the BIOS system, the second operating system can be installed. When installing the second operating system, it can be installed by means of an external disk, or by using the second operating system installation package pre-stored in the memory. The present invention does not limit the method of installing the second operating system.

[0038] Subsequently, step S340 is executed to run the second operating system and create a virtual operating environment. The virtual operating environment can be implemented by installing a virtual machine under the second operating system. Creating a virtual operating environment includes the steps of creating a virtual machine suitable for installing the second operating system, and allocating memory and storage space of the memory to the virtual machine. The memory used by the virtual machine comes from the content module installed in the computer. The storage space of the memory allocated to the virtual machine is the storage space in any storage block in the memory, and the storage space storing the storage configuration file and disk topology file of the first operating system can also be used.

[0039] Finally, step S350 is executed to read the storage configuration file of the first operating system in the memory, and the first operating system is run in the virtual operating environment according to the storage configuration file. The storage configuration file includes the boot partition and file system identifier of the first operating system. In the virtual operating environment, the storage space of the memory allocated to the virtual machine uses the format specified by the file system identifier to store system files and user files. In the virtual operating environment, the system files of the first operating system stored in the boot partition are called to run the first operating system.

[0040] By applying the above technical means, the first operating system and the second operating system can use the same physical storage together, avoiding the time-consuming copying of system files when installing multiple systems. Since the two installed operating systems are running at the same time, there is a risk of operating the same physical disk. Therefore, when providing a virtual operating environment, a file system driver will be injected into the first operating system to bridge the access of the first operating system to the file to the host system, that is, the second operating system, to ensure the consistency of the file system and realize shared access to the file. In addition, in the virtual environment, the operation of the second operating system on the file can be restored, which improves the file operation authority of the host system, that is, the second operating system, and facilitates the management of file operations.

[0041] According to an embodiment of the present invention, after the storage configuration file of the first operating system is written into the memory, a first method and a second method for installing the second operating system are provided to the user so that the user can select the method for installing the second operating system. If the user selects the first method, an operating system installation environment is established to install the second operating system. The first method for installing the operating system is steps S330 to S350 of method 300, which will not be described in detail here.

[0042] If the computing device receives the user's selection of the second method, the memory is partitioned to obtain a first disk block with the first operating system installed and a second disk block without the operating system installed. The memory partitioning can be completed using a disk partitioning tool, and the present invention does not limit the memory partitioning method. The second disk block is an empty disk area, and then the second operating system is installed and run in the second disk block, providing the user with multiple ways to install multiple operating systems in the computing device.

[0043] According to one embodiment of the present invention, under the first operating system, a service program of the first operating system is registered. After the second operating system is installed, the service program of the second operating system is created. A communication connection between the service programs of the first operating system and the second operating system is established. The service programs of the first operating system and the second operating system establish a communication connection and communicate through a bus of a computing device. The first operating system and the second operating system can send message files through the service program to achieve data intercommunication between the operating systems.

[0044] A multi-system installation method in the present invention is suitable for execution in a computing device, by obtaining a disk topology file of a memory under a first operating system, generating a storage configuration file of the first operating system according to the disk topology file, and writing it into the memory. After installing the second operating system, the storage configuration file of the first operating system is directly read from the memory under the second operating system, and the first operating system is run in a virtual operating environment. The first operating system and the second operating system both use one memory, and the two operating systems can be run simultaneously without partitioning the memory. When installing the first operating system under the second operating system, the system files of the first operating system do not need to be copied for a long time, and the installation of the first operating system in a virtual environment can be completed, thereby reducing the time for installing multiple operating systems.
