if Linux is corrupted you can even access the Windows instance because it overwrite the boot loader.

Sir could we do this in live production environment

@TechArkit 4 года назад

If there is a boot failure or corrupted grun you can use this procedure to recover. However manually deleting and trying for recover is not recommended in Prod environment. "DO NOT PLAY WITH PROD UNTIL YOUR SURE WHAT YOUR DOING"

Do it when your RHEL 7 is going to expire, before a month of RHEL 7 expiry.

@jangitisreepal1761 3 года назад

instead of hoping that your grub is in /dev/sda partition.... you would have run the "find /boot" command at grub prompt to get the exact partition where /boot exists....

@TechArkit 3 года назад

Okay, Thank you. However in Emergency mode grep not work.
