Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sdb5,
using the following options: sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
Confirmation request before suggested repair: __________________________________
The boot of your PC is in Secure mode. You may want to retry after changing it to non-Secure 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 20.04 LTS entry (sdb1/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)
