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.

I'm just not sure what I am doing wrong here. It boots on every single other computer in the house (3 different ones) but when I try to do a single boot on my system 76 laptop it just won't do it. What am I doing wrong?? It has custom firmware on it

Is secure boot turned on?

[–] BD89@lemmy.sdf.org 2 points 2 weeks ago (1 children)

Yes I have LUKS encryption enabled so I think I have to have secure boot enabled. Should I try to disable it?

[–] Telorand@reddthat.com 2 points 2 weeks ago

I would do further research, as this is based on my experience with VMs, but some ISOs refuse to boot when the VM is set to Secure Boot.

I wonder if that's why you're having trouble. I believe drive encryption and Secure Boot are separate protections (one being disk encryption and one being a way to assert system integrity). Trying to boot from a USB might be causing Secure Boot to freak out, since it's not the system your BIOS expects.

My initial thought is that you should be able to use LUKS without Secure Boot, but please don't take my word for it. Do further research. I am not an expert in this, just a passing enthusiast trying to help point you in a direction.
