CentOS with Cacti Won't Boot after Editing GRUB

[kwitzatz]

I have Cacti on CentOS, 5.10 I think. No one had the password to login to the server, GRUB also had a password. GRUB was Cacti specific, it had Cacti labeling.

I found instructions, non-Cacti specific, for editing GRUB, so I booted to a Live Linux flash drive and deleted the line from grub.conf that had the password, similar to:

password --md5 $1$9sdflksdf/sdf44k

Upon rebooting to CentOS I get a GRUB command prompt. GRUB itself does not load.

I booted back into the Live Linux flash drive and am now unable to mount the CentOS boot partition, the file system is unknown and it states the partition has a bad superblock.

Does anyone know how I can repair GRUB? Do I need to reinstall Cacti specific GRUB, if so, how do I do this?

Thanks
