I have some more info. I tried W7 64 bit beta on my HP system, figuring if I want to take it off I have a backup image. On my HP Pavilion m8000n, the restore operation from an external USB takes 45 minutes to an hour. But because my m9515y has RAID, it needs the Windows driver
to work correctly. So when I boot the Paragon Restore CD based on Linux, guess what? I have to restore using "reduced graphics safe mode" which has to run overnight. I can't even use the Backup Capsule feature of the Paragon to create a backup image on a separate partition. This RAID just stymies at every turn.
So now the only avenue that seems like it might produce some results is to create a bootable external USB, if possible, so that I can boot from it and restore from there. It's really a nightmare. I don't understand why they put together a machine configured with RAID that only has one HD!!! Give me a break!!
