I have installed first Kubuntu (sda3), then installed Ubuntu (sda4) and finally Linux Mint (sda5) on the same SSD (back to back). I want to remove Linux Mint from the disk and from the grub menu. But since I have installed Linux Mint as final, grub customization works only on Mint.

I plan to remove sda5 partition but I am afraid if I lose the grub menu. How can I safely remove Linux Mint (sda5) and get control of the grub menu to Ubuntu (sda4)?

Thank you in advance.

Boot into Ubuntu, reinstall grub (maybe sudo update-grub is enough), remove the Linux Mint partition and run sudo update-grub.

Also, don't worry. Just make a Live USB before doing any change. You will always be able to set things straight again, in one of the bad cases by doing a so called chroot. I would actually encourage you to fail and try to fix it, you will learn a lot.
