In EFI mode, the default Microsoft standard EFI boot loader is used.

To expand functionality when booting in UEFI mode, you can switch to the GRUB2 bootloader.
However, booting with Secure Boot enabled on all computers is not guaranteed.

Switch between EFI loaders Microsoft or GRUB2, you need to run the batch file on a flash drive in the EFI/boot folder
_MICROSOFT_EFI.bat - switches to the Microsoft bootloader
_GRUB2_EFI.bat - switches to GRUB2 bootloader

You can always see which boot loader is active by file in the EFI/boot folder
[MICROSOFT_MODE] - Microsoft loaders are active
[GRUB2_MODE] - GRUB2 boot loaders are active

When using the GRUB2 boot loader in EFI, you can add Acronis True Image 2018/2019/2020, Acronis Disk Director 12, Kaspersky Rescue Disk 2018, Ñlonezilla, and TeraByte Image for Linux, Parted Magic, Ubuntu Desktop amd64. (download both in UEFI and BIOS)
