Problems with Grub setup
Problems with Grub setup
Hello everyone, I’ve had a dual boot setup with Windows and Linux Mint before. When I attempted to switch to Ubuntu, things went wrong. After resetting everything, cleaning the Windows installer, and reinstalling both OSes, I noticed that when I boot into GRUB, it loads settings from my Linux Mint installation instead of the Ubuntu one. This is unusual and confusing. What could cause this, and how can I resolve it?
Some distributions install grub into the EFI partition, along with it's configuration files. Not all do, but that is one valid way to install grub. What this means, is that even after deleting all partitions of the said Linux installation, it's grub might still linger on and have it's configuration in the EFI partition. You can even have many grub installation in the EFI partition. If for whatever reason the default UEFI entry is the old grub UEFI entry, updating grub settings from the current Linux OS will not fix things - unless the said command also ensures the grub instance it is controlling is also the default UEFI entry (which, IMHO, it should not do unless the user specifically ask it to do it, since there might be situations where the user does not want it to be the default on purpose). Overall there is too much guesswork with the level of information OP has provided. Post your whole partition layout and contents of the root of the EFI partition and "EFI" folder on the EFI partition. That way people here can help you =).
