Startup Repair

Unplug the HDD with Windows 8 on in it and follows the directions in this tutorial. Note: You may have to run startup repair up to 3 times. Once the disk with Windows 7 boots on its own, then you can plug the drive with Windows 8 back in and reformat it if you wish.

You must Partition - Mark as Active the Windows 7 partition or it's 100mb System Reserved partition (preferred if you have it) Active first before running Startup Repair - Run 3 Separate Times or it will NOT work to write the System Boot files. Unplug all other HD's first.

If you have any further problems plug back in the Win8 HD to make a screenshot of your maximized Disk Mgmt drive map using the Snipping Tool in Start Menu, attach using paper clip in Reply Box.
