[Bug 1901095] Re: install 20.10 from USB stick failed

[Steve Langasek]

The error in the log is:

Oct 22 20:15:06 ubuntu grub-installer: info: Running chroot /target grub-install  --force --target x86_64-efi "/dev/sdb"
Oct 22 20:15:07 ubuntu grub-installer: Installing for x86_64-efi platform.
Oct 22 20:15:18 ubuntu grub-installer: grub-install: warning: Internal error.
Oct 22 20:15:18 ubuntu grub-installer: grub-install: error: failed to register the EFI boot entry: Operation not permitted.
Oct 22 20:15:18 ubuntu grub-installer: error: Running 'grub-install  --force --target x86_64-efi "/dev/sdb"' failed.

This indicates that Ubuntu was unable to register itself with your
system's firmware, and therefore after reboot the installed system may
not boot up correctly.

What sort of system are you installing on?  Please attach the output of
'sudo dmidecode' from this system.
