a at a:~$ sudo efibootmgr  --create --disk  /dev/sdb --part  7  --label  "grububuntu"  --loader   "\efi\ubuntu\grubx64.efi"  --verbose
Could not prepare Boot variable: Function not implemented

I ran this command thinking it might work and give a result similar to this one I found in a thread..
efibootmgr -v

Thank you
