As we know all those files are on the CD so when I click on the USB Drivers Extras Installer that is on the desktop, it asks for the CD.

Any way to get it pointed to the extras on the USB stick now?
Not a big issue as long as the main OS can be installed. That is the main reason I want it.
I don't have a spare drive to attempt an install from USB stick to see if the basics work or not but guessing the main OS should be OK and CD Extra's will have to be hand-done.
