So I've been trying to use my old hdd from an older Acer system but the hard drive can't be booted into(stuck in windows boot manager)? 
Like the other than the HDD the system came with, the system won't boot at all, a quick research did confirm it was because of UEFI but I can't change it for some reason. I tried everything. This system is a day old.
