Comment 43 for bug 568050

I did not use gparted to setup my partitions I used fdisk and mkfs and everything works fine; I'm sure gparted would work if you used "sudo gparted /dev/mapper/(array)". If you just open gparted via menu it sees the disks separatelywhich will not work (ie. /dev/sda and /dev/sdb).

You command line is not your strong point try 9.10 CD or another live boot CD (which worked in past) and partition your setup. Then stick in 10.04 for the install.
