File descriptor 63 (pipe:[117936]) leaked on lvs invocation. Parent PID 25261: /bin/bash
Unmount sdb1 from /media/ubuntu/Windows 7 Home Premium 64 bits/ to avoid special characters (& or \ or space) incompatibilities
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sda3,
using the following options: sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Blockers in case of suggested repair: __________________________________________
The current session is in BIOS-compatibility mode. Please disable BIOS-compatibility/CSM/Legacy mode in your UEFI firmware, and use this software from a live-CD (or live-USB) that is compatible with UEFI booting mode. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode. This will enable this feature.
Confirmation request before suggested repair: __________________________________
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to EFI mode.
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.10 entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
The boot of your PC is in BIOS-compatibility/CSM/Legacy mode. You may want to retry after changing it to UEFI mode.

Ce partitionnement étrange est une spécialité de Ubuntu 20.10 quand on choisit "Effacer le disque et installer Ubuntu" à l'étape "Type d'installation". On peut voir le même partitionnement dans mon post :
http://forum.ubuntu-fr.org/viewtopic.php?pid=22358656#p22358656
Pour moi, ton installation est conforme à ce qu'on peut attendre avec l'installateur de Ubuntu 20.10 : ça devrait marcher.
EDIT : ce serait utile que tu donnes le nom
complet du modèle de ton ordi et son fabricant. On pourra peut-être t'indiquer comment procéder pour démarrer ton Ubuntu.
