I realise this is more of a generic Linux question & not directly Manjaro, but Im hoping you can help regardless as it’s so hard to find good advice. I will be using Manjaro to complete this task.
I recently replaced Ubuntu with Nitrux on a 2nd partition. Now when I enter the UEFI bootmanager screen (F12) I can still see Ubuntu as well as Manjaro & Nitrux.
I removed this entry using sudo efibootmgr -b 0003 -B & it was apparently successful. However, after a reboot this entry was back again.
How should I get the removal to persist?
Deleting a boot option
Assuming the configuration in the first example, efibootmgr -b 4 -B
could be called to delete entry 4 and remove it from the BootOrder.
I have tried both 3 & 0003 & in both cases it is deleted but it returns after a reboot.
It is a very old topic but i will revive it only to post the solution: some uefis tend th generate entries in the menu automatically, if they see the efi folders and files. That was exactly the case with my old ubuntu entry and lenovo insyde uefi. So i actually had to mount the ESP partition from a live session and delete the ubuntu folder.
