PC will not boot to windows after phys-x card removed

Currently I can not boot into Windows 7. I installed an old nvidia 9800gt video card for phys-x in addition to my GTX 980ti. Then I noticed (probably due to no drivers yet) it made my pc slow, could not access nvidia control panel to make it a phys-x card, and it was very loud. Not wanting to deal with the noise, etc... I removed the 9800 video card. No I can not boot into windows.

In the Bios I can boot from my windows 7 disc, however if I try to do system repair, a message pops up saying " This version of system recovery options is not compatible with the Version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows." I do not have current recovery disc that I want to use.

Any advice on how I can get back in to Windows, possibly flashing the bios, etc...? I know I can reinstall Windows 7 and wipe the ssds and mechanical drive (not too big of a deal as my crucial files are backed up). Is there a way to just upgrade now to Windows 10 for free and skip reinstalling windows 7 first.

Double check all connections to the harddrive and motherboard make sure its all good. Then have you tried safe mode for windows?

If you already had upgraded, I would recommend making a boot-able USB drive stick with Win 10 on it. It could work anyway actually, I'm not sure. But first check all cables.
