I did a simple manipulation in Yast bootloader tool (moved one menu item up) and then the boot stoped to work (no operating system…). So i reinstalled suse. Now when I boot I have the grub prompt instead of the usual menu.
What to do?
I have linux installed on /dev/sda6 and windows on /dev/sda1. Suse 11.1
Ordinarily most here would suggest just booting the DVD into Repair and using YaST Boot Loader module there to reinstall grub (this assumes you installed from DVD rather than the LiveCD). However, I think you may have run into a YaST bug that was just recently fixed; your grub installation may be borked and/or the grub menu file may have been corrupted. I don’t know if the patch has been released to the Updates repository yet; even if it has, that won’t help you just yet. But you can fix all this from the command line using the grub shell, but first we need to know how grub was initially installed and also to inspect the grub menu for errors. So if you have the DVD, boot into Rescue and login as root. Or the LiveCD, after startup open a terminal and switch to root (the “su” command). Then do the following:
mount -t ext3 /dev/sda6 /mnt
cat /mnt/etc/grub.conf
cat /mnt/boot/grub/menu.lst
Post back here the output of the cat commands and we can take it from there.
