This article shows you what the Linux system GRUB installation steps are. The content is concise and easy to understand. It will definitely make your eyes shine. I hope you can gain something through the detailed introduction of this article.

GNU GRUB is a multi-operating system boot manager. GNU GRUB is derived from GRUB (GRand Unified Bootloader). GRUB was originally designed and applied by Erich Stefan Boleyn.

The first method: 1 We add a disk to a redhat 5.4 system, create a partition, and format it.

Add a disk to a system in a virtual machine, I think everyone should be familiar with it.

Here I added a disk called sdb

# fdisk /dev/sdb Create a partition/dev/sdb1

#mkfs-t ex3 /dev/sdb1 Specify the file format of ext3 to format a disk partition

2 We create a directory called boot under the mnt directory

#mkdir /mnt/boot

Grub files are located in the/boot directory.

3 Mount disks to this directory

# mount /dev/sdb1 /mnt/boot

Installation requires writing files under the/boot directory, so mount them.

4 Installation We use grub-install to install grub

#grub-install –root-directory=/mnt /dev/sdb

- root-directory = This option specifies the location of the grub installation

At this point, we use this new disk grub has been successfully installed, we create a virtual machine, use this disk as a boot disk you can see the grub editing interface, then go to specify the root directory, kernel, etc., of course, this is the latter thing.

The second method: the contents of the grub directory generated after installation with grub-install are the same as the contents of the/usr/share/grub/i386-redhat directory under our current system, so we can also copy the file and then use the grub command to install grub.

1:#mount /dev/sdb1 /mnt/boot is still mount

#mkdir /mnt/boot/grub Create a directory of grubs

3: #cp /usr/share/grub/i386-redhat/* /mnt/boot/grub

Copy all the files of the former to the grub directory

4 #mount/dev/sdb1 uninstall

5 # grub Running grub command will pop up a black edit box

grub> root (hd1,0) Enter root (hd1,0) Enter (hd1, 0) indicates the first partition of the second disk

grub> setup (hd1) Enter setup (hd1) Enter This is installation

grub> quit Enter quit Enter Exit

At this point mount/dev/sdb1 to/mnt/boot and check the grub directory, you will find that you have the required files, and then use to create a new virtual machine to verify it.

Linux versions are: Deepin, UbuntuKylin, Manjaro, LinuxMint, Ubuntu and other versions. Deepin is one of the best Linux distributions in China; Ubuntu Kylin is a derivative distribution based on Ubuntu;Manjaro is a Linux distribution based on Arch;LinuxMint's default Cinnamon desktop is similar to Windows XP and easy to use;Ubuntu is a Linux operating system based on desktop applications.
