FIG. 3 shows a flow diagram of a method 300 for multi-system operation according to an exemplary embodiment of the invention. The multi-system operation method 300 of the present invention is suitable for execution in a computing device 200. A first operating system is running in the computing device. The computing device includes an internal memory and an external memory, and a first boot configuration file and a first boot file adapted to boot a first operating system are stored in the external memory. The present invention does not limit the kind of the first operating system. A first boot file is stored in a first sector of the external memory and includes a first boot entry for booting the first operating system. The first boot entry records the location where the external memory stores the first operating system, i.e., the location of the sector in the external memory. The first boot file is used for determining the position of the external memory for storing the first operating system according to the first boot item. The first boot file may be implemented as an mbr file, and the type of the first boot file is not limited in the present invention.
The first boot profile is stored in a location where the first operating system is stored, i.e., a sector storage where the first operating system is stored in an external memory. The first startup configuration file comprises a first startup configuration item, the first startup configuration file is used for being started in advance when the operating system is started, and the kernel of the first operating system is loaded into the internal memory according to the first startup configuration item so as to start the first operating system. The first startup configuration file may be implemented as a bcd file, and the type of the first startup configuration file is not limited by the present invention.
When the first operating system is started in the computing device 200, the first boot file is read first, and the location in the external memory where the first operating system is stored is determined according to the first boot entry of the first boot file. And then storing a first starting configuration file of the first operating system from the external memory, and loading the kernel of the first operating system into the internal memory according to a first starting configuration item of the first starting configuration file so as to start the first operating system.
In the method 300 of the present invention, step S310 is executed first, a second operating system is installed, and a second boot item of the second operating system is added to the first boot file to generate a second boot file. The second boot entry states the location where the external memory stores the second operating system, i.e., the location of the sector in the external memory. The second boot file includes a first boot item and a second boot item for booting the second operating system. The second boot file may be configured to boot the first operating system according to the first boot entry, and may be further configured to determine a location of the external memory where the second operating system is stored according to the second boot entry.
Subsequently, step S320 is executed to add a second boot configuration item of the second operating system to the first boot configuration file to generate a second boot configuration file. The second boot configuration file comprises a first boot configuration item and a second boot configuration item for loading the second operating system kernel. The second boot configuration file may, in addition to booting the first operating system according to the first boot configuration item, load a kernel of the second operating system into the internal memory according to the second boot configuration item to boot the second operating system.
Subsequently, step S330 is executed to generate a first boot manager according to the second boot configuration file. When the first starting manager is generated, an option for selecting to start the first operating system is generated according to the first starting configuration item, so that when a user selects the option, the first starting configuration item of the first operating system is executed to run the first operating system. And generating an option for selecting to start the second operating system according to the second starting configuration item, so that when the user selects, executing the first starting configuration item of the second operating system to run the second operating system, and then generating a first starting manager according to the option for selecting to start the first operating system and the option for selecting to start the second operating system.
Since a plurality of operating systems including a first operating system and a second operating system are installed in the computing device 200, a boot manager is introduced to manage which operating system is booted. The first boot manager may be implemented as a grub manager, and the present invention does not limit the type of the first boot manager. The first boot manager may be stored in a location where the first operating system is stored or a location where the second operating system is stored, and the present invention does not limit the location where the first operating system is stored in the external memory. After the boot manager is introduced, the first boot entry and the second boot entry of the second boot file are further used to determine a storage location of the first boot manager in the external memory.
Subsequently, step S340 is executed to boot the second operating system according to the second boot file, the first boot manager, and the second boot configuration file. When the second operating system is started, the second boot file is read, the storage partition of the external memory of the first boot manager is determined according to the second boot item of the second boot file, then the first boot manager is operated according to the storage partition of the first boot manager, and then the second boot configuration item of the second boot configuration file is executed according to the first boot manager to start the second operating system. When the first boot manager executes the second boot configuration item of the second boot configuration file, the second operating system needs to be booted, so that the option for selecting the boot of the second operating system is selected by default, and the user does not need to select the option.
Fig. 4 is a diagram illustrating booting of the first operating system and the second operating system after installing the second operating system according to an exemplary embodiment of the present invention. As shown in FIG. 4, the first operating system may be implemented as a windows7 operating system and the second operating system may be implemented as a uos operating system. The first operating system and the second operating system have the same guide path when starting and share one set of guide mode. Specifically, when the first operating system is started, after the bios self-test program is executed, the second boot file is read, the storage partition of the external memory of the first boot manager is determined according to the first boot entry of the second boot file, then the first boot manager (not shown in the figure) is run according to the storage partition of the first boot manager, and then the first boot configuration entry of the second boot configuration file is executed according to the first boot manager to start the second operating system. The second boot file may be implemented as an mbr file and the second boot configuration file may be implemented as a bcd file.
When a second operating system is started, after a bios self-check program, a second boot file is read, a storage partition of a first boot manager in an external memory is determined according to a second boot item of the second boot file, then the first boot manager is run according to the storage partition of the first boot manager, and then a second boot configuration item of a second boot configuration file is executed according to the first boot manager to start the second operating system.
When the first operating system and the second operating system are started, the guide paths are the same and share one set of guide mode. And in the manner of booting an operating system shown in FIG. 4, modifications to the boot of one operating system may affect another operating system; and easily causes one system to enter twice the corrupted file system, causing the system to crash.
Therefore, it is necessary to separate the booting of the first operating system and the second operating system to avoid mutual interference. Subsequently, step S350 is executed to construct a virtual operating environment in the second operating system, construct a third boot file and a third boot configuration file in the virtual operating environment, and construct a second boot manager according to the first boot manager and the third boot configuration file, so as to boot the first operating system in the virtual operating environment according to the third boot file, the second boot manager, and the third boot configuration file. Specifically, a virtual disk address is obtained according to a physical disk address stored in the external memory of the first operating system, then a third boot file and a third boot configuration file are generated according to the virtual disk address, and the third boot file and the third boot configuration file are stored in the virtual disk. When the virtual disk address is obtained according to the physical disk address stored in the external memory of the first operating system, the first operating system stored in the external memory is mapped to the virtual disk file, a virtual machine is constructed, the first operating system stored in the virtual disk of the virtual machine is obtained, and the virtual disk address of the first operating system stored in the virtual disk is obtained.
The third boot file includes a third boot item for booting the first operating system, and the third boot configuration file includes a third boot configuration item for loading the first operating system. And when a third boot file and a third boot configuration file are generated according to the virtual disk address, a third boot item is generated according to the virtual disk address, so that the virtual disk address stored in the virtual disk by the first operating system is determined according to the third boot item of the third boot file. And then generating a third startup configuration item according to the virtual disk address, and generating a third startup configuration file according to the third startup configuration item so as to run the first operating system according to the third startup configuration item of the third startup configuration file.
