Well, I tried again to install RC7 today and again it hung (or after 3 hours of waiting) on the 'finishing installation' section.
I rebooted and allowed it to do it's rollback thing. It rebooted automatically and then disaster..........wouldn't boot. Something to do with the bootmanager.
Anyway, after a little frustration I have installed Vista on the partition I was attempting to install RC7 to.
I have run easybcd to try and sort out the boot problem, but no matter what I try, the system only boots to the new Vista install.
How do I restore my original drive? It's in RAID0 and still accessible from the new install, except now it's listed as the 'D' drive.
