Make sure you've got oscdimg.exe in your System32 folder, then open a command prompt (as Administrator if using Vista) and paste:
Oscdimg.exe -m -h -n –b"C:\Users\your_username\Desktop\expandedSetup\boot\etfsboot.com –h "C:\Users\your_username\Desktop\expandedSetup" C:\Win7.iso
Adjust the paths for etfsboot.com and the expandedSteup folder if you need to. I've managed to make and burn an iso using this but not had time to install yet.
Chimp
Guys my 3 setup files including the expandedSetup folder is moved to D:\Windows 7 as I was preparing my C: for Windows 7.
What should my cmd line switch look like?
EDIT
okay im trying this:
Oscdimg.exe -m -h -n –b"D:\Windows7\expandedSetup\boot\etfsboot.com –h "D:\Windows7\expandedSetup" D:\Win7.iso
but at the cmd prompt all i get is :
