@ -483,6 +483,12 @@ If, for any reason, no `proxmox` entry can be found in the UEFI boot menu, you
can try adding it manually (if supported by the firmware), by adding the file
`\EFI\proxmox\shimx64.efi` as a custom boot entry.
NOTE: Some UEFI firmwares are known to drop the `proxmox` boot option on reboot.
This can happen if the `proxmox` boot entry is pointing to a Grub installation
on a disk, where the disk itself not a boot option. If possible, try adding the
disk as a boot option in the UEFI firmware setup utility and run
`proxmox-boot-tool` again.
