Hi, so I recently built a PC with the following specs:

Mobo: ASROCK Asrock 775i65G R3.0
CPU: Core 2 Duo Q6600
RAM: 2GB DDR

And I went to install Windows 10, only to get the error "Please select proper boot device and restart" I thought there was something wrong with the USB so I tried reinstalling it and testing it on another machine and it worked perfectly fine. I looked up solution and tried turning on Legacy USB and i just ended up getting "there was a disk read error press CTRL + ALT + DEL to restart"
Please help!
