I am attempting to update my computer's operating system with ubuntu 12.10. How do I update my operating system to ubuntu 12.10 when I am already using 12.04? How can I create a disc onto which to load ubuntu 12.10 O/S from the ubuntu 12.04 O/S?
there are two option
1- update by using Terminal
2 - update by using update-manager
2.1 open update-manager
2.2 click Settings in the Update Manger
2.3 then select Normal Releases from the Release Upgrade menu.
2.4 check for upgrades again, and you’ll be notified that Ubuntu 12.10 is available for upgrade.
2.5 Click the Upgrade button to get started.
If you are updating from 12.04, you can simply update through the update manager. Since 12.04 is a LTS release (Long Term Support), you will first need to go to the window Software Sources and in the last option of the third tab (Updates) state that you are interested in being informed of every new release of Ubuntu (first option in the drop-down list). You will need to enter your code.
Now you can close the window, open the software updater and it will tell you that Ubuntu 12.10 is available.
Another option is to burn it to a disc or make a USB for booting by downloading the image from www.ubuntu.com and use either Brasero for burning CD's or the USB creator application to make a start-up USB, which you can boot from upon system start-up.
I'm a bit confused by the title of your question. Are you using Windows or Ubuntu already?
