Product QW814AA Model 120-1135 Serial 4CS20409MO
Windows 7 64-bit
I installed beta version of Windows 8.
When i bought this computer i had burned my recovery disks. When i went to usr the recovery disks to install clean windows 7 it said the first disk did not burn. So now i cannot install windows 7. I don't know what to do to get windows 7 back

Does the recovery manager work? Reboot the PC and at the HP welcome screen, tap the F11 key to launch the recovery manager. Select the factory reset option.
If that doesn't work, you will either have to contact HP and order a set of recovery disks, or you can try this workaround:
If you can read the 25 character Microsoft windows 7 product key, you can download plain Windows 7 ISO files to burn to DVD's for the version of windows that came installed on your PC, and that is listed on the Microsoft COA sticker on your PC's case.
Burn the ISO using the Burn ISO option on your DVD burning program and burn at the slowest possible speed your program will allow. This will create a bootable DVD.
Use the 25 character product key on the PC to activate the installation.
The key will activate either a 32 or 64 bit installation.
Then go to the PC's support and driver page to install the drivers you need.
Link to the W7 ISO file downloads is below.
