I'm using Windows Vista, however, the OS had numerous problems so I decided to fix it with the installation disc. Yet, I can't seem to find it so I'm planning to use Ubuntu as the OS and backup the files from Vista. Is that possible? If so, can you explain how it could be done.
Note: It's possibility it could be either Windows Vista OR Windows 7. Also you may noticed that I'm new to Linux OS, so I need help switching over from Windows to Linux.
