I'm having an issue installing Ubuntu 12.10 desktop on an Intel S5520SC system. When it tries to install grub it gets a fatal error that it cant find /dev/sda. If I tell it to select a different destination only /dev/sdb and /dev/sdb1 show up.
This is a fresh install with no EFI set and SATA is set to IDE.
Update: Fixed the issue using this: https://help.ubuntu.com/community/Boot-Repair as you can see in the log file i have some raid setup that is interfering with the install. It's odd in the fact the in my BIOS its set to IDE Enhanced.
