Earlier today, I had to install VMWare on a Linux host that had UEFI. Fortunately, there is a guide to how to do this on the VMWare KB, however at the end, the part “Reboot your machine. Follow the instructions to complete the enrollment from the UEFI console” is not clear on what exactly you need to do.

In order to get this to work on my Acer Aspire, I did the following(note: I’m not sure what exactly is required, as I was messing around with several settings).

1. Reboot your system and add a password in the BIOS. Smash F2 when the system boots. Alternatively, GRUB should have an option to go to the BIOS. (this step may not be required)
2. Generate the keys as shown in the VMWare KB article.
3. Copy the .der file to /boot/efi/EFI/debian
4. Reboot the system.
5. You should get a screen that says ‘Perform MOK Management’. Enroll your key from here. See this site for more details.

And that should be it. It’s not hard to do, but it is not clear and may be different for each manufacturer.
