Windows 7 ISO not booting from DVD drive?
- by chum of chance
I've downloaded Windows 7 x64 Pro Upgrade from the volume license center. I've also downloaded the Windows 7 USB/DVD download tool. I'll burn it using this tool and while it will show up in Explorer as if the burn worked correctly, when I try to boot to the DVD on startup, I get a "No operating system found" error (this is a newer Lenovo).
My Ubuntu Live CD works fine, am I missing something? I read that there's problems if you try to burn a 64bit copy from a 32bit computer, but I'm currently running Win7x64, so that shouldn't be a problem.
I've also tried burning with ImgBurn and Windows 7 built ISO burner, no success. Obviously there's a step I'm missing here, what gives?
