grub-install: error: failed to register the EFI boot entry: Input/output error.

[William Wilson]

When running the installer, grub fails to install to /dev/sda with the following error: "grub-install: error: failed to register the EFI boot entry: Input/output error."

I have confirmed /dev/sda is the correct target device. A 22.04.1 installation on the same hardware works fine. The same crash occurs regardless of secure boot being enabled/disabled.

I think this is the important part in the log file and I think it is something with your EFI firmware or some words like that.

The python traceback isn't really useful here.

William,

can you compare the output of debconf-get-selections | grep grub on both systems? Are both still installed and functional?

Thanks!
