- Connect the USB drive On a Win7 Machine
- Partition the USB disk drive NTFS, if the disk is large (i.e. 1TB, reduce active partition to say, 6GB, I used gparted on Linux ;-p)
- Run DISKPART in command line
- LIST DISK
- SELECT DISK n (n is the number matching the USB disk obtained above)
- CLEAN
- CREATE PARTITION PRIMARY
- then copy the content of the DVD with XCOPY e:\*.* /s /e /f j: (e: = CD drive, j: = USB drive)
