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

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.

[@GradyBroyles]

Great topic!!

[@ecw0647]

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.

[@lordsiomai]

in the end, it really depends on the OS you tryna use.

[@cperzam7700]

@@lordsiomai Yeah just as lord says most OS don't mind booting from extended partition/logical partitions, yet some OS like Windows can't boot from logical partitions.

[@JusticeWatch]

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

[@johanmyreen1027]

(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.

[@karlscheel5159]

That's correct! To prove it, I just set my Linux desktop calculator to Programming Mode, set the base number-system to hexadecimal, and entered the following to represent the largest 32-bit value: FFFFFFFF Next, I added one to this hexadecimal value, to include Sector Zero (@00000000) in the total amount of available sectors: FFFFFFFF + 1 = 100000000 Since each sector is 512 bytes, I then multiplied the above value by 512 (in decimal) as follows: 1. I hit the multiply key. 2. I then changed the base number-system to decimal (This automatically converted the hexadecimal value to the decimal value of 4294967296.). 3. I then entered 512 and pressed the equal sign to get the maximum amount of bytes that can be stored on *any* drive in Legacy Mode. The value I got was *2.199023256×10¹²,* which is exactly equal to 2 TiB, which I got by dividing 1024 from the *raw* total as follows: 4294967296×512÷1024÷1024÷1024÷1024= However, there is another way to store more data using a 32-bit partition-table: You could use a larger sector-size such as 2 KiB instead of 512 bytes. And that's what modern hard disks enable you to do, if you set it up within their firmware using a utility such as hdparm.

[@ErezGeva2]

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.

[@JHorse508]

Fantastic video, I learned alot.

[@luisalcantara7374]

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

[@aitchpea6011]

Cool video, thanks, that'll all be helpful when I eventually replace my laptop and put Linux on the new one. One thing: You say legacy (BIOS) boot only supports four partitions, but I'm sure I used to (back when I had a desktop with big drives) use more than four partitions using logical partitions within the extended partition area. So I'd have two or three bootable and one extended containing another handful of logical.

[@OpusFocus1968]

This is splitting hairs. The maximum number of partitions is 4 (3 Primary partitions and one extended) totaling 4. The partitions within the extended partition are "extended partitions" and aren't counted toward toward the total of 4. There was a limitation years ago and not sure if it still stands but Windows had to be installed to a primary partition and not an extended one. It's not a problem with Linux but be that as it may. Not all partitions were created equal.

[@TeamLinux01]

Just as an aside, Secure Boot also requires UEFI and unfortunately some systems, such as newer OEM laptops, don't allow you to disable Secure Boot or don't allow the user to add Machine Keys to the Secure Boot system check. Which means it will only boot kernels signed with the provided key, made by Microsoft; thankfully official Ubuntu kernels use a shim that is signed with that key, so the use doesn't have to disable it or add new keys to run an Ubuntu based OS on those machines. I think a couple other distros also use that shim and key signing.

Does this apply for only a C drive? If I boot into legacy can I still use GPT for a E or F drive that is not a boot drive?

[@davebean2886]

For MBR when you say mark the partition bootable does that mean set the boot flag as one or more of the following: boot, gios-grub, root or legacy-boot for the system partition? Also does the mount point need to be?

[@yadrak2354]

Hi Chris. I'm 8minutes, 03 seconds into the video and have a question for you. I recently tried dual booting the latest version of ubuntu with windows 7 home premium and noticed that the ubuntu boot loader took over the loading of either windows or linux. It looked like the font size it used for the loader was extremely small and hard to read. Is there any way to inscrease the font size of this boot loader (assuming it was grub?). Thank-you!

[@Ryuuzaki145]

You can probably edit that somewhere in /boot. Look how to edit grub configuration on google, you should find what you're looking for ;) (There, you can also add/edit a theme and so on. Been a while I've done that, wish I could help more)

[@nikatomuirhead3013]

Grub has about 30 active bugs which will prevent Grub from writing to the UEFi boot partition. Using systemd-boot will get rid of install issues for many people. PopOS and endless will install very well in UEFI. Endless supports secureboot.

[@thepoliticalstartrek]

Some older legacy bios on that last boards before UEFI did take over had patches to support detection and GPT on the drives larger than 2TG. This kind of throws off people that were not building at the time or installing large drives. GPT is supported and I have had Windows 10 running on one of these boards. What kind of sucks with some back up utilities on servers and virtualization was the weird server time that EFI was a thing. Really sucks when you are trying to do an emergency automatic spin up a virtual server.

[@alexsilin2713]

Chris, please correct me if I'm wrong, but EFI partition formatted to FAT32 should not necessarily be the first one on the drive. In fact, it could be placed anywhere and it runs OK.

[@phrtao]

So long as the partition has the flag set to make it bootable any hardware should find it. It is even possible to have multiple EFI partitions on one drive but this may cause problems with some hardware - especially complete PCs (such as laptops) rather than motherboards bought separately as a component.

Just a minor correction. Things that are no longer approved for use are "deprecated", not "depreciated". "What is deprecated?

Why do you prefer 500mb for the efi partition? I only gave it 299mb, and it only uses 2% of it.

[@ChrisTitusTech]

This depends on what you are doing with your bootloader. Images, icons, etc. I like to error on the side of caution and don't really care about 200 mb savings. 300 will probably be fine in most cases, but I like to account for any situation. It is a personal preference thing, and my nightmare would be I'd run out of space on it, however it is unlikely.

[@xnonsuchx]

Windows tends to not give a crap about any other installed OSes and just wants to assume you only want Windows. One thing to keep in mind w/ multi-boot is that Windows will make a 100MB EFI partition (if one doesn't exist) while some other OSes/bootloaders need more than that (up to 200MB or a bit more).
