My Gateway Laptop Harddrive died, it was a Windows 8 box that was upgraded to Windows 8.1. I moved, don't know where back up boot disks are. Got a new harddrive, got Win Pro 8.1 x64 OEI DVD, how do I get the OS onto the harddrive? When I boot laptop it says No Bootable Drive. Hit any key... but nothing happens. Can't get into bios... OK somehow I did get into a boot menu but it was empty, as in it had no options to select from. I have been reading about this UEFI thing and wonder if that is why there were no selections in the menu or if it was caused by something else. Will the laptop boot off the OEI DVD?
