Install a grub interface that can run on other computers

Purpose:Create a grub interface that can run on other computers.Pure entertainment.

Principle:According to the Linux system startup process, we only know that grub is used to guide the operating system, so we can completely, create a grub page and run it on other computers.

General process introduction:A dual-Hard Disk Linux system is required. Install a grub interface on the hard disk that is not the root device, and then take the hard disk to other systems for running.

1) Add a new disk to a Linux system. The disk must be specified as a single file.

2) Remember the location of the disk file, which will be used later.

3) create a 20 m partition on the Newly Added Disk.

4) format the partition.

5) create a boot directory under the/mnt directory and mount/dev/sdb1 to the/mnt/boot directory.

6) Run grub-install -- root-directory =/mnt/dev/SDB to install grub under/MNT. The command will automatically find the boot directory without manual specifying

7) When you view/mnt/boot, you will find that grub has been installed under the boot directory, and grub directory also has the relevant files.

8) Create a New Grub. conf folder, write the following content, and use the sync command to synchronize the file to the disk. Otherwise, the file will still be saved in the memory.

9) create a new virtual machine, but select an existing disk when selecting a disk.

11) then open the new virtual machine and you will see the newly created grub interface, but the system cannot run because there is no Kernel File.
