Grub Recovery

Jamwa · #1 11th November 2011, 08:29 AM

I have 3 machines on F15 and I wanted to upgrade to F16 using yum. The first machine was flawless and am happy to report that it is now on F16.

However, I messed up on the second one by skipping a step:

Code:

To switch to grub2, run the command su -c '/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg',

And I jumped straight into installing grub 2:

Code:

grub2-install /dev/sda

and now the machine boots but all I get is the prompt

Code:

grub>_

2 approaches:

1. Try to boot your kernel directly from the grub> prompt (grub shell) using the root, initrd and boot commands.

2. Boot a rescue disk, chroot to the installed system, run the /sbin/grub2-mkconfig script.
