Not able to boot a software raid installation - Ubuntu 10.04.1 i386

there seems to be a problem with your grub configuration.

It looks like grub has problems to load the /boot related files which are
misconfigured to be located on fd0.
Please boot into a live environment and check your grub.cfg and post the
approriate lines.

Something you should also check is:

Did you try to create a seperate boot partition on each disk which you may
want to mirror?
Are there any other disks installed besides your two IDEs?
And is the BIOS trying to load the MBR off of these disks which hold a
faulty config?

Summary: Please give us some more information.

Bye, benjamin
