1. Get a USB Thumbdrive between 4-32GB.
If the drive is larger than 32GB, Windows cannot format it as FATS32, so an alternate utility must be used. Windows can still read FAT32 partitions larger than 32GB, though some devices cannot.
However, we are going to use NTFS for the big files that are larger than 4GB.
2. Run cmd.exe as administrator and enter the following commands followed by Enter
diskpart list disk select disk # (where # is your USB drive as determined from step 2) clean (This step will delete all data on your flash drive!) create partition primary active format fs=ntfs quick assign list volume exit bootsect.exe /nt60 F: /mbr (where F: is the drive letter of your USB drive as reported with a * by list volume)
3. Copy the content from the bootable DVD
robocopy e: f: /mir (where e: is the bootable DVD and f: is the bootable USB)
