Hello. I have both Home Basic and Premium from my laptops (Dell OEM) and I want to "combine" them in one usb stick. I found all the information about the pid.txt, but when I use pid.txt from Basic to Premium sources it doesn't work. It brings the window to enter key. Entering manually the Basic key it show me that "the product key you entered does not match any of the windows editions available to install". The same if using the Premium key to Basic sources. I know that Vista sources has all editions and the key shows what edition will install. Is any way to have both editions in the usb stick without multiply folders (like AIO DVDs)?
