Linux System Administration: Adding Recovery Mode To Grub Menu

 On normal startup of the Linux system you probably see this menu every time you boot up















In this post we are going to add a recovery mode for each of these choices.

Here are the steps to create recovery mode options in the GRUB menu:

1. Log into the system normally

2. Open a terminal session, switch to root privilege or root user

3. Type vi /etc/default/grub to edit the grub file

4. Once you are in the grub file find the line that says GRUB_DISABLE_RECOVERY="true" and change it to GRUB_DISABLE_RECOVERY="false" then press esc then type :wq!










5.  When you get your command prompt back type grub2-mkconfig -o /boot/grub2/grub.cfg to regenerate the grub file



6. When you reboot the system you will see that for each choice on the menu there's an equivalent recovery mode option, you can press esc to stop the menu countdown
