Solved Need help- I want to back up my entire Operating System on a CD

Hello.
I want to install a new Operating System (It's legal, don't worry. It's Linux.), but when I install it I know that I have 2 options:
1. Keep your old operating system
2. Delete your old operating system.
Now, I sort of want to do both.
I want to back up my entire old operating system on a cd. But, I have a problem.
The CD can only download so much. It has a mb limit of about 750. I really don't want to buy a new cd, but if that's the only choice, please recommend one for me. All help is appreciated.

Welcome
A CD of any size is not the recommended medium to download your OS.
The way to go is to back up using Macrium Reflect on an external hard drive.
In lieu of that use a thumb drive (usb Drive)

How do I back it up on a usb drive?

Dowload this software

It will allow you to back up the OS. It gives you choice of where you want to back up to.
