Not sure if anyone has come across this yet. I'm trying to install Windows 7 RC1 onto a Lenovo X60s through a USB DVD drive. The problem i have though is once the original setup screen comes up and i click on Install Windows 7 after a brief moment of loading setup files it prompts me for a driver, it doesn't say which driver is missing it just asks to locate one and i can't go any further. I have no idea what driver it is asking for as it doesn't say, it also can't be asking for the SATA driver as when i go to repair installation it find the hard drive and points to my Vista installation on another partition. I hope that makes sense, any ideas? Also the copy i am using is the x86 version from the MSDN website.
