Dell recovery and restore USB not working

Okay, I had some OS issues and elected to just go ahead and restore Windows 7 (It's Windows 7 home 64bit by the way) So I order the repair and recovery usb from dell. I got it, booted from it and was confronted with a warning that "Platform not supported, the dell recovery and restore USB key may not fully restore your system" I hit continue anyways and then it attempts to perform Drive diagnostics at which point it tells me errors have been found that prevent us from continuing with the recovery process. I called dell support and they said to talk to the software department, however they had gone home. I figured, eh let's try to do it anyways. It starts the process and then gets stuck while scanning drives....and stays there for hours. So, please help?
