Hello all! I have a secondary desktop PC in the house running Windows 8.1 Pro that is used for light surfing and banking from time to time. I used this PC just today with no issue and had to run some errands. After returning home and wanting to get on the PC I noticed a blue screen with the title Recovery, Your PC needs to be repaired: the operating system couldn't be loaded because a critical system driver is missing or contains errors.
I created a bootable recovery disk using a usb drive and have used that to try startup repair as well as sfc /scannow and the chkdsk commands. Nothing has helped. I even tried the copy command to copy system32/drivers over and that didn't work either although I am now getting a different file location error. The same error pops up while trying to boot except the file is now:
Error code: 0xc000007b
One interesting thing I did notice was while in command prompt on the usb recovery disk that if I run diskpart and list volumes that it is showing the C drive as being system reserved whereas the main OS is labeled as G. I can tell that by the amount of space listed. Is this what is causing my issue? I have no idea how windows could have gone from C to G if so as I didn't do anything on the PC earlier today apart from some light web surfing and left the computer on while out and about. I have tried system restore and that fails as well. I am at a complete loss as to where to go from here other than to reformat which I'd like to avoid if that's possible. Thanks.
Below is a link to the photo album of pictures I took of the error messages. Hope these help.
