Windows 7: BSOD on boot, unmountable_boot_volume

BSOD on boot, unmountable_boot_volume

I'll make it long story short. I had turned off some unnecessary things in msconfig like some of the pre-loaded vaio software that I never used, but realized I had turned off the service that allows me to change the volume, brightness, I turned that back on in msconfig, and restarted. What has been happening since is it will BSOD at the windows loading screen, right before the screen where it asks for your password.

It will say "UNMOUNTABLE_BOOT_DEVICE" I have tried starting in safe mode, safe mode with command prompt, safe mode with networking, last known good configuration, and normally. I've also tried the "repair your computer" option in the advanced boot options, and when that loads, it just opens a low resolution windows background and shows the mouse on the screen forever. I even let it sit all night to see if it was just being horrendously slow and it was still just a blank screen with the mouse. I also made a windows repair CD on my home PC and tried using that, and it still does not repair it.

I can't even boot my laptop anymore and I've run out of ideas... It's a Windows 7 Home Premium x64 Sony Vaio VPCCW17FX, I just reformatted it back in august, I don't get what's going on.
