Copy Windows bootable DVD to .ISo/.DMG
 

I have a Windows disk I am trying to copy. I want to make it a R/W image if at all possible, but for now, I will settle for ANY....

I've tried it using Snow's Disk Utility on a MacBook with it's internal and an external DVD [R/W] drive, but it keeps failing....

Any advice? [It's a bootable disk and I want to keep it that way]
