Make a backup copy of Dell’s Windows 7 Professional OEM DVD
December 9, 2009 – 1:07 pmI always like to have backup copies of my Dell Windows’ CDs and DVDs for service reason, but I couldn’t get the Dell Windows 7 Professional 32-bit DVD to copy, it would say that my DVD+R didn’t have sufficient space. I saw that the Dell DVD was 4.8GB, so I bought a pack of DVD+R Dual Layer discs and it worked! Make sure your drive and software can handle dual layer discs.
