Solved Advent desktop not booting from disk - [B75MA-P45 Mobo]

[lewis188]

Hello, I received my new Advent desktop yesterday (specs below) however, I decided like 5 minuets in that I REALLY hated Windows 8. I decided that I was going to install Windows 7. I put the disk in and got to the part where it had to restart I was greeted with this: WINDOWS. -BT\Windows\System32\winload.efi
0xc0000428.
Not really sure what this means, but it would let me boot back into Windows 8 and my BIOS. I headed into the BIOS (Click Bios II) I changed the boot order to only boot from disk. However it booted into windows and I was greeted with the same problem as before. I tried disabling everything other than the disk reader still the same problem.

Specs:
Manufacturer: Advent
Model No: DT2412
i7-3770 3.4Ghz (OCed to 3.8)
16Gb RAM
B75MA-P45 Mother Board.

What do you mean "Obtained", where have you got the Licence key from?

There're non legit copys, however, they both work on the 3-4 other PCs I tried them on.
