Doh :( My Ubuntu experiment came to an abrupt halt. I chose the “Install under Windows” option which had a nice clean installer, set everything up nicely, a total breeze. I made sure Vista still worked and booted Ubuntu. It started up and everything looked promising … And then stopped at “BusyBox” with an (initramfs) prompt. That post suggests I should switch my SATA from IDE to RAID, but they’re already set to RAID.
