All i removed are tablet and speech support basically.
I am using "Windows 7 usb dvd download tool" from microsoft to do this and it is returning an error: "The selected file is not a valid ISO file" .
If there is an alternative to this tool that would work, i would appreciate it. If not, any other solution?
The iso i modified is one from "digital river content", a W7 SP1 ultimate x86.
