I have many different Ubuntu versions installed on my HD. I'd like to rename some of their entries in GRUB2 boot menu. I have tried two approaches.
1) Like mentioned in http://ubuntuforums.org/showthread.php?t=1347756 - This is not working, I have 9 different lines with SDA11 sections visible in my 30_os-prober file. Am I supposed to modify all of them while in real boot menu only one entry for this partition is visible after sudo update-grub?
2) I have also tried Grub Customizer application, but it just overpopulates my boot menu with duplicate entries.
Instead of doing it hard way by modifying all the entries visible in 30_os-prober file, I would like to know if there is an easy solution? I may be overlooking something, but if there is no easier way, is this supposed to be harder than with GRUB1 for a reason?
