Issues with Windows booting, Windows repair and trying to reinstall

You can also check in the BIOS for the make.

I just went and checked in the BIOS as advised (I would have done this sooner, but I was sure the text string that identified the drive was really generic...but I just didn't look at it properly before)

It's a Western Digital (P0-WDC WD5000AAKS)

Running some tests now

I used the Seagate Tool on both of my drives, ran basic tests, both passed. Used the Seagate tool due to reports of the WD tools not working too well sometimes.

Used Partition Wizard on my main drive, listed in previous post, and it found 1 single error block

How about a camera snap of PW drive map and listings?

Then further check the HD with all other HD's unplugged by running Partition Wizard Check File System.

Next rightclick on the 100mb System Reserved partition (preferred if you have it) or C to Mark Partition Active, highlight the HD to run Partition Wizard Rebuild MBR Video Help. Reboot to see if Win7 will start and if not run Startup Repair - Run up to 3 Separate Times

If these fail and you're ready to try reinstall, highlight the HD, from PW CD run Partition Wizard Wipe Disk Video Help. Create and format a NTFS Primary partition which you mark Active to try Clean Install Windows 7. Partition Wizard Create Partition - Video Help
