So I just got a Asus 5xxl i5 and I had to replace the hard drive. I had a windows 7 disk so I installed windows 7 and then upgraded to 10. My issue is when I take out the 7 disk and reboot it gets stuck on a black screen and repeats the same message no matter what I hit. if I put the windows 7 disk back in and restart it goes to the hit any button to boot from disk screen, I don't hit anything and windows 10 boots up fine. without the disk in my only option is to enter the bios over and over. please help This is driving me insane.
