Ubuntu – How to make space in /boot/efi without resizing the partition

bootdual-bootgrub2partitioninguefi

I upgraded to 20.04 yesterday. I just noticed that in Ubuntu Software there is an update for Dell Inc. System Firmware, but my system does not have enough space to run the update.

Is there any way except by resizing the partition with gparted (or similar) to clean this location up from Ubuntu?

I want to keep the Windows partition.

  • In my case I resolved it by simply finding some (probably) unimportant files and moving them to a backup folder outside of /boot/efi. For example, the boot-repair/log files came to around 3 MB, and some of the /EFI/Microsoft/Boot files had folders for languages I would probably never need. This allowed me just enough space to perform the update.

    The only problem was that on power up it went straight to Windows, without giving me the grub menu after the BIOS screen. I resolved that, in Windows, by opening a command prompt as system admin, then running

    bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
    

    But I'm sure you're aware of all the warnings, so be careful to do any backups before this.
