I have three usbs: Kingston, cruzer, and corsair, and none work with that lexmar removable bit flipped. So I'm forced to use RMPrepUSB and firausb. Since RMPrepUSB doesn't need the iso to be extracted, doesn't this mean that the iso will get extract at the time of installation? so more work loads for the usb if i do a lot of installation? on the other hand, winsetupfromusb puts the iso's extracted files onto the usb so when it install windows, the only thing it does is read the files?
