Hello everyone, i have a problem with hard drive. I tried to add 1TB HDD from my old pc to new one as a second hard drive, ive connected everything and tried to boot my pc. I got this message "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER". I checked in bios and it didn't find my hard drive, then i unpluged all my hard drives and put old hdd from my old pc with windows 7 and it worked, but of course i got bsod. Now even my first hard drive doesn't work i get the same message. Can anyone help me ?
