EDIT:
I reinstalled grub bootloader and regenerated the grub Configuration with the same commands in steps 12 and 13
before rebooting my computer the output of efibootmgr -v is
BootCurrent: 0001 Timeout: 0 seconds BootOrder: 0000,0001 Boot0000* grub_uefi HD(1,GPT,d20bff6e-6f1e-c549-9f1b-505a302fd42c,0x800,0x100000)/File(\EFI\grub_uefi\grubx64.efi) Boot0001* UEFI: Generic Flash Disk 8.07, Partition 1 ...Gibberish..BO but After reboot the output is:
