Installing Karmic x86 cdimage (23-Sep-09 nightly).
Dell OptiPlex 960, 4Gb RAM, with Intel ICH10 fakeraid setup for Windows XP RAID 1.

1) I resized NTFS partition to make 20Gb of room for Ubuntu.
2) Run Karmic installer, it seems fakeraid correctly, and I choose Manual partitioning, created ext4 on new partition.
3) Installer goes thru entire installation, but fails on grub step with following error:

"Grub package failed to install into /target. Without GRUB boot loader, the installed system will not boot."

4) I tried opening a terminal as su, and ran
  grub-install --root-directory=target /dev/mapper/isw_bfdafeice_ARRAY (which is the correct mapped disk, I believe) and it fails with "grub-probe: error: no mapping exists for isw_bfdafeice_ARRAY5". Auto detection of a filesystem module failed.

5) Then I tried
  grub-install --module=ext4 --root-directory=target /dev/mapper/isw_bfdafeice_ARRAY
and it fails with, "You attempted a cross-disk install, but the filesystem containing target/boot/grub does not support UUIDs".

So, left with a system that won't install GRUB so I can't boot. Happy to provide more detail.
