I am wondering if it's possible to say put all of the different Windows disks from OEM, upgrade, retail, etc. all onto one DVD and then be able to choose which one you'd like prior to installing Windows. I've seen this sort of DVD in the past but was wondering if there is a walk-thru or instructional/tutorial on how to do one.

I'd really appreciate the help. Thank you.

Here's a tutorial - should help.

FLyakite has a good tutorial on this. It's how I started. I also made a post on how to add multiple images to a dvd and make it bootable with menus using cdshell. it's in this forum somewhere
