Bit slow on the uptake here I'm afraid. Is it possible to chainload Jaunty, all partitions ext4, with my existing Hardy ? I will of course choose not to install grub to mbr during the Jaunty installation. Also is it correct that I will only be able to mount the ext3 partitions from within Jaunty but not vice versa ? (Saw somewhere that it is possible now.) Lastly will Jaunty's gparted be able to see Hardy's partitions ? All rather confusing for me, but I really would like to try Jaunty without getting into trouble. Regards Edit: Forgot to mention - I am windowless now so grub and XP not applicable here.
