There are many links about what happens next.
Here's one -> http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/
Note -> I rarely have to use those commands you read there.
Here's a Windows CD if you feel you can't mouse around Ubuntu. But it may not support the USB drives to backup to.
Be sure to use the Direct Download link.
