If you have Tech Support then use it. You paid for it.
They should help you find out why Win7 won't install.
If not, what did you pay for?
You don't need a warranty return or service request, just plain old telephone tech support to help you work through the issues.
Use it repeatedly until you get the questions answered which were asked here, and enough advice to find out what must be done to get Windows 7 installed.
