UEFI vs Legacy BIOS Boot | GPT vs MBR (DOS) | Explained

In this video, I go over the differences between UEFI vs Legacy BIOS Boot. This includes the differences between partition tables GPT vs MBR (DOS).

UEFI
-Faster Boot
-Advanced Graphics
-Secure Boot
-Relys on EFI Partition
-Difficult to Install

GPT
-Support for Large Drives 2TB+
-Typically UEFI

Legacy Boot
-More compatibility
-Easier to setup
-Rely on a Bios Boot Flag
-Text Graphics

MBR (dos)
-Convert to GPT for UEFI
-Windows does not like MBR with UEFI
-2 TB / 4 partition Limit

You make a great teacher Chris. I mean, I was actually having Grub issues after installing Linux on my Windows - I thought I should change to Legacy Boot and face whatever jargon comes off it but you laid it straight already. Thanks man.

Just a thought, how about adding some screen shots to this video? As a Linux newbie I find visual aids invaluable...

These videos would be far more effective
If you showed graphics, screenshots, etc
To demonstrate what you are talking about
instead of your face.

I was day dreaming when you explained . Keep it short and sweet..

You can get around the four partition limit in MBR by making one of them an extended partition. I've loaded up to ten different linux Os's on an MBR 1 TB disc easily and have them all bootable simply by putting them in that extended partition. I've found it's far easier and practical than messing with GPT. It works best with debian and ubuntu based OS's and some arch-based, but the arch-based can be more problematic and will sometimes mess up the boot record which can *sometimes* be fixed with boot-repair but not always. I usually put the swap and an ntfs partition (that I label "share" which is accessible by all the OS's and even Windows on first, then making the extended partition and then divide that into as many partitions as you want.

(1:55) With MBR you can not use sectors beyond 2 TB at all. The 2 TB restriction is not on the size of an individual partition. The problem is that the MBR partition table only uses 32 bit sector offsets for the partition boundaries.

This information is soooo good to have, really useful as I currently sit mid-install on my system and trying to understand what options work best for me; this is leagues better than the dozens of "Just use this partition table" recommendations I see everywhere, you really get into the what and why these kinds of partitions exist what is exactly what I needed

[prasadsawool]

Wow, this is the most informative video I've seen on youtube.. Thanks

[Yuenix]

Thank you brethren I'm glad you've made it clear multiple times in the detailed explanation and breaking down the differences in MBR legacy and Uefi and by partition system.

Probably the first guy who suggested me to see the comment section for other advice👌

Next 15 minutes i will understand why i prefer Legacy over UEFI and if i was wrong all the time. See ya in 13 minutes!

Hi,
Two comments:
1. MBR support 4 primrry partitions, but a primety partition may be an extension pattion that allow adding more logic partitipn, by that you could have more than 4.
2. I used a bios boot with UEFI that did not support the EPI partition type, only Fat32 partition type. It was probably a mistake, but nobody is perfect.

Am I the only one who spent half the video rejoicing at the cute snowman on the wall? :)

[VideoLeakPolice]

I'm restoring a 2005 computer and I get invalide partition table when I try to install Windows.

[skyjmoney]

I love the knowledge I gained from here!

[luisalcantara]

Excellent job reasoning forward the most effective way for a computer to behave suffering their capabilities appropriately balanced by the portion of the systems supporting each software or out of schemes into Windows processors etc etc

[sajjadhoviegar]

Your noise cancellation is so great that every time you stop speaking I think the video is stucked!

[EllantEladar]

Thank be to God for giving me this information about my UEFI and Legacy Chris Titus. I really messed up and I think I need a reboot

[JamesWilson-pqqp]

Fantastic topic Chris, we need so much more information, especially seeing the different bios. And how to use a solid state drive labeling as mmblk over sda. So many abbreviations, what does it all mean? Your background in Windows is a valuable help here as many have avoided UEFI for the last 10 years.

Man! I wish I had a tenth of your knowledge🏁
