Windows 7: Problem with laptop - Blank screen with blinking cursor

Problem with laptop - Blank screen with blinking cursor

I recently dualbooted Linux Mint and Windows 7 on my laptop. Yesterday I removed the Linux partition without thinking, and forgetting about the GRUB bootloader. I'm at a stump now. When I try and turn on my computer, the Toshiba logo appears, then the screen goes blank with a blinking cursor. I searched the internet all of today and most of yesterday, all that did was tell me to do the bootsect /nt670 /fixmbr and all it's variations.

Thing I've tried:
-Repairing it using install DVD
-Bootsect/Bootrec (used any option that would help, none did)
-Reinstalled Mint (GRUB loader reappeared, was able to boot Windows 7 loader, but when I did it went back into the blank screen)
-Reinstalled Windows 7 (didn't help)

Another problem is, when I click on repair, it shows with 3 different Windows 7 installs, Windows 7, Windows 7, and Windows 7 Home Premium. All say they are located on my primary partition, C:\.

So, is my computer a big paperweight now? Or should I reinstall Linux, boot into it, format my entire system, and reinstall Windows fresh? I have all my important data backed up on an external HD. Thanks

PS I'm running a memory test on my laptop now, I'll post results later if needed.

You want to mark the Windows 7 partition active using DIskpart from the booted Windows 7 DVD REpair console or Repair CD: Partition - Mark as Active

Next boot into Repair console, click thru to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until Windows 7 starts.

If Windows 7 will not start when marked Active, it means GRUB is interfering. Use free Partition Wizard bootable CD to Wipe the partition which had GRUB to deep clean it. Then check with PW that Windows 7 is marked Active and run Startup Repair again repeatedly until it starts - ignore any distracting messages that can be confusing.
