However, when the last installed operating system is a window operating system, the menu created by it cannot recognize the previously installed Linux operating system
In other words, users cannot enter the Linux operating system through the boot menu created by the window operating system
The user can only install a boot menu that can recognize both the Windows operating system and the Linux operating system to replace the boot menu created by the Windows operating system, which causes confusion for the user

Embodiment Construction
[0012] Please refer to figure 1 , Which shows a flowchart of a method for starting up multiple operating systems according to an embodiment of the present invention. The multi-operating system startup method stores the boot management program of an operating system in a storage component, and adds an option to the boot menu of another operating system to access the boot management program stored in the storage component. The multi-operating system startup method 100 includes the following steps:
[0013] After starting to perform a Power-On Self Test (POST) (step 110), continue to determine whether an interrupt signal is received from a user interface (such as a keyboard) (step 120). For example, an interrupt signal can be generated when the user touches a specific key on the keyboard.
[0014] When an interrupt signal is received, according to a partition table of a hard disk, a number of original partitions of the hard disk are listed to obtain a selection signal from the user ...

The invention relates to a starting method for a multiple operating system, comprising the following steps of: selecting one of a plurality of original segmentation areas of a hard disk to serve as a target segmentation area by a user in the process of executing power-on self detection; obtaining one power-on management program of a first operating system from one target starting sector of the target segmentation area, and saving the power-on management program to a storage element; obtaining one power-on menu of a second operating system from one main starting segmentation area of the hard disk; adding an additional item in the power-on menu of the second operating system for storing the power-on management program in the storage element; and after the power-on self detection is completed, providing the revised power-on menu so as to selectively start the second operating system or load the power-on management program by the revised power-on menu.
Description
Technical field [0001] The present invention relates to an operating system startup method, and particularly relates to a multiple operating system startup method. Background technique [0002] Currently, there are many operating systems for users to install on the computer as an interface for the user to operate the computer. Among them, Microsoft Windows is the most widely used on personal computers. In addition, the Linux operating system has received extensive attention due to its free software and open program code characteristics. Therefore, in order to select an appropriate operating system for different applications, many users will install multiple operating systems on the same computer. [0003] Generally speaking, if you want to install multiple operating systems on one computer, you need to install each operating system to the computer one by one through the installation program of each operating system. Then, create a boot menu to select the operating system you wan...
