I've just installed windows 10 on my Samsung SSD in my main pc for a friend (Asus Rog B350-f) disconnected my main boot drive and booted his up and it worked just fine. Infact I'm writing this post from it. However when I put it in his system It just goes to a black screen with a blinking line at the upper left hand corner. He's running a FX8350 and its an asrock board (I can't find a model for it) however it does have the old Blue and Grey Bios. Any help would be GREATLY appreciated. I've been working on this for a few days now. I do have access to a install media usb stick and have tried every Diskpart command I could think of, also watched every single video with this problem. I've also tried changing the settings in the BIOS and nothing worked. Thanks in advance guys.
