View Full Version : [ubuntu] RAID + IDE + GRUB = Error 21 : Selected disk does not exist

My computer is configured as follows:
2x160GB SATA drives in a RAID array
1x120GB IDE drive

I had Feisty installed on the IDE drive with GRUB on the same drive. Whenever I wanted to boot into Ubuntu I would select "Boot from IDE drive" and everything was working flawlessly.

I decided to install Hardy and overwrote my old Feisty installation and installed GRUB on the IDE drive again. I started getting "Error 21: Selected disk does not exist" when I tried to boot. So I followed some instructions to reinstall GRUB but I managed to overwrite my RAID MBR as well. I am now stuck with Error 21 when I try to boot from my RAID and my IDE drives.

Any suggestions?
