My parents recently purchased a new Gateway computer that came with Windows 8. The model number is DX4860-UR28. I was able to downgrade from Windows 8 to Windows 7 with relatively no problems. The issue I'm facing is that the computer will only boot into Windows 7 if the install dvd is in the drive. I've tried changing the boot order in the bios with hard drive as the primary, and still had the same problem. If anyone has run into this problem and has a solution please let me know.
