Hi Everyone,

I just wanted to share some experiences installing trying to dual boot the
newly pressed 32-bit Ubuntu 10.04.1 (with the shipped Windows 7 install) on
a VPCZ12CGX/X with (2 x 128Gb SSD).

I'd tried a while back with 10.04 and run into RAID-related errors when
trying to create partitions during the install. After checking the bug
reports it seemed there would be plenty of RAID-related improvements coming,
so I'd waited until 10.04.1 to try again. Sure enough, the partitioning now
works, and the alternate installer runs fine right through until the final
grub installation step -- where it fails.

I've had no luck installing grub with super grub disk, rescatux or using
rescue mode so far. Google also hasn't turned up a solution yet. My grub
experience is relatively limited, so it may be something relatively trivial.
Is this as a common problem? Anyone know of a solution? Is this SSD
specific?

Further details below -- any help greatly appreciated!

Paul.

Some further details:

I am keeping the shipped install of Windows 7, and attempting to dual boot.
Have successfully loaded the live cd with the usual kernel parameter changes
(nomodeset i8042.nopnp etc).

Some possibly useful command line output obtained from a live cd session is
pasted below.
