  • the Basic Input Output System In the existing operating system booting method, after the computer is powered on, the Basic Input Output System (BIOS) reads the BIOS settings to obtain the order of the boot drivers, and then checks the boot drivers in turn. Determine the disks that can be used for booting (including floppy disks, hard disks, CDs, etc.) and call the boot sector of the disk to boot. In this case, if you want to create 10 Linux-type virtual machines on one hard disk, you need to use the hard disk. Create 10 partitions, and each partition is formatted as a file system recognized by Linux.
