I fixed the boot issue by reinstalling grub using the instructions on http://wiki.ubuntuusers.de/grub_2/konfiguration
Because this page is German, I will describe in English what I did: Basically I booted from "Ubuntu Rescue Remix 10.04" (from USB stick) into a command prompt and then: sudo mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 sudo mkdir /mnt sudo mount /dev/md0 /mnt Now I could access my system partition (which was mounted on /). Install package containing the command grub-install and reinstall GRUB by writing it to the MBRs of the RAID1 members: sudo apt-get install grub-pc sudo grub-install --root-directory=/mnt /dev/sda sudo grub-install --root-directory=/mnt /dev/sdb After rebooting (works now!): sudo update-grub The system seems to work right now, but I receive an error message while booting: udevd-work[121]: inotify_add_watch(6, /dev/sdb5, 10) failed: No such file or directory nForce2_smbus 0000:00:03.2: Error probing SMB1. What does that mean? If I can fix this, then I consider my system being completely up and running again.
