UEFI vs Legacy BIOS Boot | GPT vs MBR (DOS) | Explained
C
7:39Chris TitusHOST
The older versions, you have to stick with UEFI and GPT or do a legacy and MBR.
C
7:47Chris TitusHOST
But for GRUB, you have a ton of flexibility.
C
7:51Chris TitusHOST
Most of it is actually dictated by the boot portion.
C
7:55Chris TitusHOST
So from the root, it goes into boot.
C
7:58Chris TitusHOST
And from here, you can actually put your GRUB configuration in and boot legacy from there.
C
8:05Chris TitusHOST
Now the EFI directory, which would be in boot, is typically mounted to a completely separate partition.
C
8:13Chris TitusHOST
And when that partition is set up, it's a GPT drive, it'll be set up at the very, very front of the drive.
Did LTT Get Linux RIGHT? A Pro Reacts to Their Mistakes
C
10:19Chris TitusHOST
You can recreate it.
C
10:21Chris TitusHOST
And the big one, if you're using Grub, you can easily recreate that EFI entry by just doing a Grub install and then pointing to the boot directory, the EFI directory in your boot.
C
10:32Chris TitusHOST
Sometimes certain distros will install it directly on the boot itself.
C
10:36Chris TitusHOST
Sometimes they do boot EFI.
Switching to Linux | Part 6 | 30 day challenge
C
8:53Chris TitusHOST
So I've switched from Fedora 29 as my main boot to Ubuntu.
C
8:59Chris TitusHOST
I'm still using Grub and I've redone that using Grub 2 Customizer, which I'll probably also make a video on.
C
9:06Chris TitusHOST
But overall, really, really like an Ubuntu just because of how easy it is to install and customize things.
C
9:14Chris TitusHOST
I've even created setup scripts and all these other things in the past, which I can easily use again.
The Linux Desktop Guide
C
4:36Chris TitusHOST
So I stuck to the big main line things that most new users should stick to.
C
4:42Chris TitusHOST
So Grub, SystemD, and LemonAid.
C
4:44Chris TitusHOST
I kind of go over just how to prep for installing Linux.
C
4:50Chris TitusHOST
This is kind of a big thing when it comes to the preparation of Linux, how much space you should have, have a second drive, how to create a bootable USB.

How UEFI, Secure Boot, and the Boot Chain Actually Work
Oct 14 · 11 Mentions
C
2:24CornHOST
Then that tiny thing chain loads a second stage from somewhere else.
C
2:28CornHOST
The gap after the MBR, a volume boot record, or on a GPT disk, a dedicated GRUB BIOS boot partition.
H
2:36Herman PoppleberryHOST
440 bytes.
C
2:39CornHOST
That's your operating system's first breath.
10 MINS LATER

12:47Herman PoppleberryHOST
And then the shim vulnerability, which is the other half of the current story
C
12:53CornHOST
ESET found 11 old Microsoft-signed shims, all version 0.9 or below, that can bypass secure boot on most UEFI machines.
C
13:01CornHOST
They lack MOK deny list enforcement, which arrived in 0.9, and SBAT support, which arrived in 15.3. One Oracle Linux shim trusts a GRUB binary vulnerable to CVE-2015-5281.
C
13:15CornHOST
Microsoft revoked all 11 in its June 9th patch Tuesday this year, tracked to CVE-2026-8863 and CVE-2026-10797.

And, uh, then there's a whole lot more wrong with Xorg, and yet more powerful tools to fix it.

The, the butter FS snapshot snapshot fans showed up the ZF ZFS on root fan showed up, you know, at, at one point a moderator had to switch on slow mode to just, slow down the threads.
J
23:54Jeff MassieHOST
And of course, someone suggested just rewriting Grub and Rust.
J
23:59Jeff MassieHOST
Of
J
24:00Jonathan BennettHOST
course they
J
24:05Jeff MassieHOST
Let the hilarity ensue after that post.
J
24:07Jonathan BennettHOST
Yeah.
J
24:08Jeff MassieHOST
So is the risk real? Well, one developer in the thread pointed out to CVE-2024-45774, a specifically crafted JPEG could trigger an out-of-bounds write in Grubb's JPEG parser.
J
24:23Jeff MassieHOST
Mm-hmm.

We'll be right back.
J
18:15Jonathan BennettHOST
All right, Jeff.
J
18:16Jonathan BennettHOST
The Grub is going on a diet and some other things in Ubuntu.
J
18:21Jonathan BennettHOST
What's new there in 26.10?

Other people raised European, raised European compliance rules that require an encrypted slash boot.

ULS 273: Lost Me at Technically - Spectre Again, ACME, and The Netherlands
K
33:50Ken McDonaldHOST
That's gonna be an interesting question because s- OmarchI uses a systemd-boot.
K
33:57Ken McDonaldHOST
My Ubuntu 26.04 is using Grub.
J
34:03Jonathan BennettHOST
I mean, it should be possible, I would think.
J
34:06Jonathan BennettHOST
I don't know.
J
34:11Jonathan BennettHOST
[laughs]
K
34:13Ken McDonaldHOST
I'll probably try digging into it.
K
34:15Ken McDonaldHOST
I'm still trying to, uh, f- see if I can get it so it will automatically reboot into the last one I was in, unless I specifically change, like I could do with Grub before.
K
34:30Ken McDonaldHOST
But it's al- always booting up into systemd-boot first, so I'm having to sit there and wait and select the Ubuntu 26 option.
