Website "Compatibility Alert"?

I am not sure if this is the right place to post this, please direct me to the correct place if this isn't meant to go here. Thanks.

Hello, I am planning to buy an Alienware 14 laptop but the website seems to have a problem. I have selected Windows 8 for the operating system but it gives me a "Compatibility Alert" because of it. The pop-up box says the Windows 7 Recovery Disk is not compatible with Windows 8. Obviously it isn't but I probably won't need a recovery disk. The problem is that it doesn't let you buy the computer after selecting Windows 8.

Thank you,

Kosta
