For those with Saucy and who love Super Boot Manager, I did a little tinkering to get it installed and working on 13.10. As it stands currently, there is no installation for Saucy so we will be using the one for Raring. Simply do what I did.
First, you'll need to add the source:
Next, add this to the end of the file:
sudo nano /etc/apt/sources.list
Save your changes, and update your repositories.
deb http://ppa.launchpad.net/ingalex/super-boot-manager/ubuntu/ raring main
Finally, install Super Boot Manager!
sudo apt-get update
You should be good to go! Happy modifying!
sudo apt-get install super-boot-manager
