7 Wont Boot (nor Safe Mode) Repair Not Working - HELP !!

I installed what I thought was an updated driver for a PCIe eSATA card and since then get only the Advanced Repair options, none of which work.

The nearest I get is System Restore which finds the OS and the restore points but fails with this error, reading in part:
The inst. @ 0xfba6ca53 referenced memory at 0x0021cd49. The memory could not be read.
Or words to that effect.
None of the other options work except Command Prompt and I have no idea how to use that in this situation.

I have the only options of
a) Full Win 7 install, overwriting everything or
b) Running a Win 10 disk over it and upgrading in the hope it will preserve my files and settings.
But it may also not boot because that damn driver will still be there.

Help !! I'll monitor this from my 10 drive as best I can.

I could try that I suppose. Will see if possible in the morning when there's more ambient light and I don't have such a headache.

Thanks for the idea.

Oh well couldn't resist. Tried both options, unfortunately no-go. Sigh. If only I could initiate a repair installation I could save my stuff. It's mail I'm mainly worried about . (Vista Windows Mail)
I need a new computer desperately but this one is going to have to do if I can rescue it. I do have access via Windows Explorer from 10 but that doesn't do much good as far as I can tell.

There's nothing showing in the BIOS as that card boots after the BIOS. What I need to do is to be able to repair install 7 to preserve my stuff.
I will research that, thanks.

Here is a tutorial on Repair Install by Brink.

Repair Install

The problem is you must be able to boot into a existing Windows 7 on the computer for it to work.

See if you can boot into Safe Mode ( Advanced Boot Options ). If you can boot into safe mode, uninstall the driver from Safe mode and try to boot again.

None of the above worked. Had to format and clean install.. Thanks for the suggestions.
