Grub will be installed by default, and should (someone correct me if 
this is wrong) put up a menu at boot time listing available boot 
options. Initially you'll just have the one OS (with options for 
normal or single-user modes).

When you install the second OS, you'll have the option to 
install/update Grub - and it should find the earlier one as well. 
After that, you'll find you have 4 boot options (2x OS, each with 
normal or single-user). It will default to the first entry, not sure 
which that will be.

So when you boot, it will default to one OS - but you have the option 
to boot a different one if you press a key within the 5s timeout.

No idea if there's a GUI for it - not used to using GUIs for this 
sort of thing.
