Adding boot menu entry for UEFI Firmware Settings

Unhide GRUB boot menu in sda5/boot/grub/grub.cfg

Boot successfully repaired.

You can now reboot your computer.

Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 20.04.3 LTS CurrentSession entry (sda1/EFI/ubuntu/shimx64.efi 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\ubuntu\shimx64.efi
