En fin d'opération, après avoir généré le rapport, boot-repair m'indique "an error occured during the repair". J'avoue qu'avec le spam de "possible missing firmware", je m'attendais à ça...
Voila le rapport de boot-repair :
boot-repair-4ppa125 [20210116_0905]
============================= Boot Repair Summary ==============================
Default settings: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
sdb2,
using the following options: sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.10 entry (sdb1/efi/****/shim****.efi (**** will be updated in the final message) file) !
User settings: _________________________________________________________________
Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.

The number namespace in-between is configurable by system installer and/or
administrator. For example, you can add an entry to boot another OS as
01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
the menu; and then adjust the default setting via /etc/default/grub.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sdb2,
using the following options: sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.10 entry (sdb1/efi/****/shim****.efi (**** will be updated in the final message) file) !
