Hello and thank you for choosing JustAnswer.com
I see you have 2 questions with the same thing in them.....
Did you mean to do this?
I would recommend using an ISO file, to rip down the CD.
Then you can save that single file to your thumb drive
Okay, we can work out of this question. NO worries.
WHat you need to do, is create an ISO file from the CD you have. This is called Ripping. Using a small application, many are available for free.
Then copy the ISO file to your thumb drive.
When you want to restore the disc, you load up the ISO file into another small application called Magic Disc. Magic Disc emulates a CD drive. And you have an EXACT copy of the disc, that you can install programs from, or whatever. It acts just like the original disc, and has all the same files.
If you would like me to do this FOR YOU, I can.
I can do a remote session, and connect to your computer, and while you watch, show you how.
