So somehow along the line my partition changed from mbr to gpt and there is no 100mb partition at the beginning of the drive before the C: partition.
I just tried reformatting, changing the partition table to mbr and preforming a system reimage, but it actually reformatted itself BACK to gpt.
My question is how can I change the partition table back to mbr without having to do a clean installation of windows.
I've spent hours installing drivers on this machine and I'd rather not redownload them all and install them - that would be a nightmare.
