I need help in reinstalling GRUB2 in my system as I’ve messed up completely. I’m able to boot from grub and run the system normally. But when I restart, system couldn’t find grub file. I’m also as confused as system. In one of the thread, jdd mentioned the below steps, but I need some help.
mount /dev/sda1 /mnt
mount --bind /dev dev
use the arrow and back key to do the same for sys and proc
chroot . (dot)
How to run rescue? Should I reboot my system to go to grub-rescue? If so, how. I’m able to reach grub command line, but not grub-rescue.After chroot ., I need to use yast. How should I set yast? More details would help me in resolving the current issue. I need step-by-step command as I’m novice.Looking forward for a quick reply as grub has become unstable with so many changes.Many Thanks!
