SUSE 11.3 (Error Loading Operating System Fix)

Try re-installing grub.
Whilst booted with the USB drive - open a terminal and become su, and follow this

You enter this ---------------- grub

Computer returns like this ---- grub>

You enter this ---------------- find /boot/grub/menu.lst

Computer returns like this ---- (hd0,1)

Here, (hd0,1) is Grub's pointer to my openSUSE installation. Your pointer should be the same, I edited this example to (hd0,1).

You enter this ---------------- root (hd0,1)

Computer returns like this ---- Filesystem type is ext2fs, partition type 0x83

You enter this ---------------- setup (hd0)

You see several lines like this --- Checking if /boot/grub/stage1 exists ... yes Computer finally returns this-- Succeeded.......Done

You enter this ---------------- quit

You enter this ---------------- reboot
