I'm trying to Split my partition for my hardrive but when i click on the Primary The new button and the Extend button are grayed out I'm doing a over Install because I want to keep my files that is still on the PC. and is telling me that 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 disks.
My PC was previously working but then an update caused it to go hay wire and would not load into the desktop anymore.
