I have been trying to install Window 7 for a Win/Linux dual boot system. I tried partitioning the Windows boot drive GPT and installing in UEFI mode but I keep getting an error message that Windows can't find or install a valid partition. As far as I can tell secure boot is disabled. I partitioned the drive with another one of my computers before installing it in the current machine. The boot drive is a WD 750GB black drive.
