Can I install Jolicloud replacing ubuntu and have the choice of which os to boot on bootup?

I don't see why not, Jolicloud appears to be based on ubuntu so should be grub compatible. All you should need to do is install and choose the ubuntu partition(s) to install to. Alternatively boot into mint, run gparted (if you installed it) and delete the ubuntu partition(s) then run sudo update-grub in a terminal to reset the boot options to just mint. You should then be able to boot the Jolicloud disc and install it choosing the empty space to install to. I haven't tried Jolicloud myself so not sure what install options are available.

Thanks, excellent explanation.
Well,I spoke too soon,it said no partition after using gparted and updating grub.Must have done something wrong,I had to re-install Ubuntu to make Mint work.

Sounds like you had Mint installed first then installed Ubuntu. If this was the case, Grub was installed with and controlled from the Ubuntu installation. Deleting Ubuntu destroyed Grub so running sudo update-grub in Mint would do no good. What you would have to do is follow this procedure

Just insert Mint where ever it mentions Ubuntu.

Or you could just go ahead and install Jolicloud. It does use Grub and will pick up the presence of your Mint installation when it is installed.

Yep, that's what I did! Thanks,
