I'm trying to install Windows 8 on a friends computer, who had formatted the hard drive before they gave it to me. When I get to the step in the installation process where it asks me to choose which drive I want to install Windows on, there are two partitions that show up, one 150 gigs and the other 450 gigs. (Which is weird, because it is a laptop. I can't seem to delete and merge the drives either.) When I try to choose a drive and move on, windows tells me "We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files." I've tried the disk part things where you clean the drives, but it still won't work.
