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.

Does Libreboot prevent unauthorized USB boot, aka somebody boot another OS and wipe your drive? (lemmy.world)

I understand LUKs can be used to encrypt your data. But what would prevent somebody plug in a USB with and just wipe my drive?

On traditional BIOS like Lenovo, HP, Dell and even Framework you can set a supervisor password that locks the boot menu. So nobody can boot from the USB.

Coreboot is different though. I spoke with Starlabs whose computers run Coreboot, and apparently you can have the boot menu password. OTOH, Sys76's Coreboot doesnt allow such things.

I ask because i want to libreboot my T480, but the number 1 thing i worry is unauthorized USB boot.

This one: https://libreboot.org/docs/linux/grub_hardening.html#grub-password

seems to only lock the ability to edit the grub entry freely, aka press "e" to change stuff when grub fails to boot.

Especially in terms of wiping the drive like OP is asking. If their goal is simply wiping data, they can just put a drill though it. Or if it's to wipe and replace the OS, they could presumably whip the drive out, format it on something else and do what they like with it, then put it back in the original computer or something like that.
