You're going to have to call HP and get an exact amount.
Probably between $15 and $20.
If you can read your windows 7 product key you can make your own W7 installation DVD.
If you can read the 25 character Microsoft windows 7 product key, you can download plain Windows 7 ISO files to burn to a DVD 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.
