probleme GNU GRUB version 2.04

Bonjour, j ai recement booter UBUNTU sur une cle a travert une autre LiveUSB, et depuis je n arrive plus a utiliser mon systeme d exploitation principale qui est windows 8, quand je demarre mon PC sans brancher la cle boote je tombe sur une page noir ecrit dedans (GNU GRUB version 2.04 /n   minimal BASH-like line iditing is supported...).
pour avoir le choix de choisir entre Ubuntu sur ma clé et Windows sur mon disque dur il faut à chaque fois insérer la clé au démarrage.
J'ai installé sur ma session Ubuntu le BOOT-REPAIR et j'ai créer un rapport Bootinfo et  voici le lien qui m'a été génère:  https://paste.ubuntu.com/p/4bfGKQvRgZ/
aidez moi svp je veux que je puisse acceder directement a windows sans etre oblige a inserer ma cle et sans perdre mes donnees sur disque dure vu que c est tres important.
Je vous remercie.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sdb2,
using the following options:        sda2/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix 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 The OS now in use - Ubuntu 20.04.2 LTS CurrentSession entry (sda2/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)
