Umm, yeah, you broke your raid.  Grub is now booting just fine, but
Linux is unable to find /md0, which is probably specified either as the
root device in your menu.lst file, and/or in your /etc/fstab file... Not
sure how I would even go about fixing this now.. though I suppose you
could try changing the partition type back to Raid auto-detect.  If
there were no other changes to disk that might just start working again,
but it's a risky proposition.. I would start by backing up whatever data
is still accessible on those drives before making any other changes.
