Answer #1
You need to copy a noDVD crack to your install folder…There is normally a crack folder in the ISO…But if it’s not there,,Download it here:

Answer #2
if its asking for the disk you need to use the no-cd crack. most releases will include a crack along with install instructions.
copy the crack from the disk to the install directory and replace any files.
