Thank you so much Grabben. oscdimg.exe -b<path to etfsboot.com> -u2 -h -m -l<ISOLabel> <path to dvd> <path to save .iso> This command works perfectly. I tried this command to create an ISO file, burn to dvd disc, it worked. I also try to use ISO feature of 7Customizer, but it gave error during the setup. I combine 7Customizer and the guide "Put Windows 7 on USB key", the setup runs faster than comparing run setup from DVD disc. I want to share this guide on this forum, but I do not know how. Bout oscdimg. Just go to start > programs > windows aik > deployments.. and paste this oscdimg.exe -b<path to etfsboot.com> -u2 -h -m -l<ISOLabel> <path to dvd> <path to save .iso> oscdimg -bE:\dvd\boot\etfsboot.com -u2 -h -m -l7cDVD E:\dvd E:\7Cdvd.iso
