I built a new computer with everything new expect my HHD which I took from my old PC. I just turned everything on and it is running, but when I try to partition out the HHD, it wont let me because it says "Windows cannot format drive. Error 0x8004242d" Can someone please help me? And at the bottom it says "Windows can't be installed on a drive 0 partition 1" and then I click more details and it reads "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disk." I have no idea what this means!!??
