Windows 7: unintentional Roll back - aughhh!

UPDATE:
So, I see that my old Windows 7 partition on Disk1 is marked as (system, boot, active, pagefile, crash dump, primary). This is what my machine is booting from. It's a standard IDE drive.

My new Windows 7 (the one I want) is now only marked as (active, primary). This is a HW Raid0 stripe using the mobo sata raid controller.



How do I get back to booting from the right place? Is it likely a windows thing or a bios setting?

END UPDATE
NEW UPDATE
It seems that the boot manager on disk 0 has been corrupted. I've tried using the BCD program referenced elsewhere on this board, but ended up with a still incorrect bootmgr.

luckily, I can get to everything, so I think my install of retail home premium is just going to happen sooner than it was otherwise going to.

Still like to hear if there's a way to straighten this out.

END NEW UPDATE



I installed the intellitext driver the other day as an 'optional' update. I think it created a restore point

This morning, it started complaining, then firefox crashed for the first time ever, then I was at the desktop with nothing - no task bar or explorer.

Then I hit ctrl-alt-del, I chose logout and got a blue screen. Then I restarted and I ended up "back in time" ... old desktop, old icon configurations old everything. I'm either booting from a leftover partition with a previous install, or I triggered a roll back to an ancient restore point.

Anyone seen this? Suggestions on how to get back to the correct partition?

Debug info needed?
Thanks - I'm kinda freaked out right now and might have lost a bunch of stuff, but thankfully most of my stuff is either online with google, or on my nas box.
