Windows won't boot after removing cmos battery

[iprice85]

My computer wouldn't boot and I saw on a forum to clear the bios by removing the battery.
Sure enough my computer now turns on but I get this error and I don't know how to fix it.
I have tried fixboot fixmbr chkdsk, system restore and startup repair, all to no avail.
It wont start in safe mode either.
I want to avoid a fresh install if possible, I foolishly have data that isnt backed up.
I would really appreciate some help with this, I am stressed!

You may need a fresh install.

Change sata controller mode to value it had before CMOS reset.
Possible values are: IDE, AHCI, RAID.
Try all until you find the right one (if you don't remember it).

Yes, to elaborate the BIOS reset reverts all BIOS settings to factory default. If Windows was first installed under a different setting (for example, a different SATA mode) you'll have to set that setting properly to boot Windows.
