Repair Windows 7 startup drive in another win 7 machine?

[Dave Lane]

My observatory computer drive acted up tonite. Can't get windows 7 to boot. It offers to let me run start up repair or boot normally to windows 7.

Trying to boot to Win 7 causes a reboot after it starts to load maybe 30-45 second in. Up till then it has the normal Windows screen with the 4 colors. Taking startup repair causes it to show a loading file progress bar then blank screen with lots of disk activity and then seemingly the twilight zone. 20 minutes and nothing seems to happen.

So I put the drive into another machine with a functional Windows 7 install and I can see the problem drive without any difficulty. Load files from it etc.

So is there a way to repair the problem installation from the current machine? I'll have to take it home to make any repair DVDs so I'm hoping I can fix it while I'm still here.

Thanks for any help!
