Using openSUSE bootloader, want to install openSolaris


I currently have openSUSE installed dual booting with Ubuntu. My current school uses openSolaris so I would like to install it on my system. I’ve already toyed with the live cd.

The question is, openSolaris will overwrite openSUSE’s boot loader. What’s the best way to recover this? Should I create a backup of my …/grub/menu.lst?

Or does this do the trick using the live cd?
