Hi Guys thanks for your help so far, but I still have problems:
Ok, so I successfully made the ISO and burned it to a DVD, then I tried to install from the booting DVD and again it doesn't let me.
This time after choosing "Upgrade" it tells me something like:
"You were trying to install from a boot CD ... please take out the CD restart your computer, and when in windows start the installation from the CD" ?!?
Of course I also tried this, but with the same result as installing directly from my desktop.
problem not solved yet.
