From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Enabling secure boot later on (lemmy.ml)

So, I've installed Manjaro quite while ago, and I let secure boot disabled during installation. Dang! Is there a way to keep (most of) my system and enable secure boot and LUKS after the fact?

It depends on a single variable - does your motherboard support manipulating the secure boot keys? I've only done it on prebuilt dells and dell laptops, but some other manufacturers also allow it.

The procedure is very simple, but has many steps. Don't get discouraged! I remember ArchWiki having a very thorough guide that worked for me.

The gist of it is you provide UEFI firmware the cert to trust and then use the keys to sign your kernel image. I've never had to deal with signing the modules (mostly nVidia related, I think), but the procedure would be the same.

I think, I can install keys in my AMI bios. So, basically, I'd create some keys, sign the kernel with it, reboot, install them keys in UEFI, enable secure boot, and, fingers crossed, I'd boot?

You might have to enable Audit mode or similar - again, depends on the manufacturer - to generate the keys. But yes, essentially that's the gist of it.
