Well, I did a clean install of Windows 8 onto the hard drive out of an office computer, for a friend. I simply put the hard drive into my system, formatted the disk, and then used a boot USB to install Windows 8 onto the drive, through my computer. Everything works fine when I use the HDD in that computer, but nothing will work when I put it in the computer that it needs to work in. I need help figuring this out ASAP.
