As long as grub 2 doesn't like raid, you should use grub1 (grub-legacy) 
instead of grub2. Here you can find instructions [1] (probablly you use 
raid0 instead of raid1, but never care).

Boot with any Ubuntu install CD (live, alternate, server...), run a 
terminal (rescue mode for example) and follow instructions from point 
#9.f to #9.m (not earlier only if you have enabled dmraid support during 
first installation before formatting). You need internet conection 
(wired easiest) to get grub, or modify sources.list to include cdrom or 
found .deb mounting the cdrom. Just replace 
/dev/mapper/isw_beeaakeeaa_five with /dev/mapper/isw_bfcjcejdfb_Volume05

Hope this helps.


cheers!
