I assumed you had already worked through the steps for Troubleshooting Windows 7 Failure to Start
which BlueRobot linked in Post #2, however since you apparently didn't see the step where you could easily copy out your files from unbootable Win7 and instead spent $90 having Best Buy do it for you, then if Win7 is still on the HD you can try them now.
In that case Startup Repair run up to 3 separate times automates all of the repair commands and tests, while the manual steps are also provided so you know everything possible that can be done has been attempted.
If you'd already done this and/or decided you prefer the Clean Reinstall then carry on.
