How to use GRUB2 with UEFI for secure booting Ubuntu?

Question

I have a mirco computer board such as BeagleBone black.How I can make secure boot of Ubuntu in it using Grub2 and UEFI?

Answer 1

You cannot use GRUB/UEFI with BBB. You have to use U-Boot since that's the only officially (and actually) supported boot loader.

Please refer the user guide.

However, if you explain what kind of security you need, people here may suggest different solutions.
