I have a disk with a Ubuntu 20.04 partition and a 18.04 partition. If I update the 18.04 one to 20.04 I will have problems in grub?

Yes, grub is smart enought, so when you are booting, you will see a list of all Operating Systems available, and yes, if you have multiples versions installed from the same 20.04, grub will show in wich partition which one is installed
