[0039] In the embodiment of the present invention, when loading the boot program, a first instruction is searched in the code of the boot program, and after the first instruction is found, the user selected system information called by the first instruction is obtained.

[0040] Optionally, the first instruction is used to indicate a target operating system selected by a user, for example, the first instruction is a grub_env_get("chosen") instruction.

[0041] It should be noted that if the target operating system is selected by the user, then in S201, during the process of starting the target operating system, when loading the boot program, the user selected system information retrieved by the first instruction in the boot program is obtained.

[0042] If the target operating system is selected by default, then in S201, during the startup of the target operating system, when loading the boot program, the default selected system information retrieved by the first instruction in the boot program is obtained.

[0055] Furthermore, according to the trusted verification result of the kernel file and / or the initial root file system, the target operating system is loaded and started, thereby completing system startup.

[0056] Therefore, the path information of the target operating system can provide path input information for subsequent trusted verification.

The user selected system information identifier can be understood as the information identifier of the target operating system selected by the user.

[0061] Furthermore, the user selected system information retrieved by the user selected system information identifier is obtained from the system information of all operating systems.

[0062] It should be noted that the user-selected system information identifier can be understood as the menu identifier of the system startup selected by the user; the user-selected system information can be understood as the menu of the system startup selected by the user; the system information of all operating systems can be understood as the menu of all operating systems.

[0063] In the embodiment of the present invention, optionally, S202, acquiring path information of the target operating system according to the user selected system information, includes:

[0064] Obtain path information of the target operating system called by the second instruction in the user-selected system information.

[0065] In an embodiment of the present invention, taking the target operating system selected by the user or selected by the system by default as the Linux system as an example, the second instruction includes a Linux instruction and / or an initrd instruction, wherein the Linux instruction is used to load the Linux kernel file corresponding to the Linux system, and the parameter following the Linux instruction is the path information of the Linux kernel file, such as / uImage-5.4.18-37-generic; the initrd instruction is used to load the initial root file system corresponding to the Linux system, and the parameter following the initrd instruction is the path information of the initial root file system, such as / initrd.img-5.4.18-37-generic.

[0066] Therefore, the user selected system information in the boot program is parsed to find the second instruction, and after finding the second instruction, the path information of the target operating system called by the second instruction is obtained.

[0067] It should be noted that the user selected system information includes instructions that need to be executed when the target operating system is started. In addition to the second instruction mentioned above, the instructions also include an insmod instruction for loading a part_gpt module or an ext2 module.
