I can't comment on the systemd's bootctl, because I don't use it, by as I |
| 97 |
understand it 'efibootmgr --delete-bootnext' will clear the BootNext entry in |
| 98 |
UEFI settings and does not take a boot entry number as a variable on the CLI. |
| 99 |
I can't answer why "7" in your entry above returns a comment about "Boot entry |
| 100 |
0001" ... which is obviously absent. |
