I have a triple-boot system using Mint 9, Mint 12 and Zorin. In the boot menu the first two are specified as written but Zorin simply appears as Ubuntu. Can anyone tell me how to change this so that it appears as Zorin. I've read a GRUB2 manual but I'm afraid it's as clear as mud to me so words of one syllable please ( updating etc/grub/default to change the boot order, etc, has proved no problem but I can't see where to edit the titles ). Thanks in advance for your help.
