[Bug 997885] [NEW] grub fails on RAID

[Horadranin]

Public bug reported:

Hi again.

I'm trying to install 12.04 in a PC with RAID (ICH10R) but it nearly impossible.
I already submitted bug #990744 because the Ubuntu installer can't create swap partition. Eraserix suggested not use any swap as a workaround, and I did it. But at the end of installation grub fails with the message "grub-installer: error: Running 'grub-install  --no-floppy --force "/dev/sda"' failed."
The problem is it must be installed in /dev/mapper/isw_bajfdgcbgf_Sistema which is the RAID set. A window pops up asking me to select another device, to continue without grub, or to cancel the installation. I double check the /dev/mapper/isw_bajfdgcbgf_Sistema thing is selected and click ok button and it fails again: grub-installer: error: Running 'grub-install  --no-floppy --force "(hd0)"' failed
It happens that I don't have a IDE disk or DVD device plugged in my PC!

I also choose continue without a boot loader and used my 10.10 install
to update grub entries. Then I rebooted the computer and choose 12.04 to
boot, but the boot process stops at initframs or something. I can type
help to see commands but I really don't have any idea to what to do.
