I had a computer with windows 8.1 installed but the HDD died. So I bought a new one and installed windows 8.1 with SATA mode IDE. Everything was fine untill I shut it down. When I tired to open it said that there were no bootable device. I tried everything and finally when I changed SATA mode to AHCI it saw the HDD but could not start Windows, so I changed it back to IDE and it started Widows as if nothing had happened.
Whenever I shut down the computer and try to start it, the same thing happens, and I do all these steps again.
I also tried to install windows 8.1 on AHCI mode, but the same thing happened again. But this time I had to switch to IDE and then AHCI again.
Also, when I pick restart option, not shut down, there is no problem. It restarts just fine.
Do you have any idea why this is happening or how can I fix this?
