The main difference between classic BIOS and UEFI is that regular BIOS can only read MBR partitioned drives. Regular BIOS also only reads the first sector (512bytes) and if it is not a boot sector it will try the next device. Now UEFI can read gpt fat32 formatted drives and can boot from ANY partition or folder on the drive (via UEFI console), although boot files are usually stored in EFI folder on the root of boot drive. UEFI reads a file with EFI extension.

What Chris has not made plain as day here is that Apples implementation of the Extensible Firmware Interface is actually contained on a small 100mb boot partition of the computer hard drive itself and is not contained in resident flashable ROM as is the scenario on a PC. A Mac has no directly addressable BIOS as such and merely a few TPM enabler chips on the mobo itself. Universal Extensible Firmware Interface is a hybrid of both traditional BIOS and EFI hence the 'Universal' moniker. Indeed to make Mac OS boot on generic intel hardware as in the case of an Hackintosh you need to create a bootable EFI partition installation with a piece of sofware called 'Chameleon bootloader' or 'Clover' to enable this pre boot environment that Mac OS requires. In practice it is a bit more complicated than this as older BIOS only mobos often require a special bespoke crafted DSDT file that enables the EFI instruction set to handshake with the legacy BIOS. If you ever intend to go down the hackintosh route check out the Tony Mac OSX86 Hardware Compatibility Lists (HCLs) and choose a more current UEFI model that is fully supported and you will save yourself a lot of grief and heartache this way. It is a truism to say that if your mobo supports UEFI out of the box it is more 'vanilla' and henceforth more hackintoshable by its very nature. Editing and compiling DSDT file translation tables is not for the technologically inept or faint of heart.

Just the clarity and accuracy I needed to succeed. Thanks! Tip in case useful: The only way I know of booting to Windows 10 on an NVMe M2 drive on a PCIe bus with a MB that doesn't supported booting to such a drive and bus is to: • Put Windows 10 iso on a USB memory key using Rufus (GPT / UEFI (non CSM) / FAT32). • Put the Clover bootloader files on a different USB memory key formatted with a single FAT32 partition. Make an NVMe driver available (there are web pages on how to do this - essentially copy the NVMe driver from the "off" folder to both the "BIOS" and "UEFI" folders, all in the "\EFI\CLOVER\drivers" folder structure). • Make the NVMe drive GPT from within an existing OS. I used "MiniTool Partition Wizard". • Boot to Clover. • Install a UEFI installation of Windows on that drive from Clover. I did this by dropping to the UEFI command line and running "efi\boot\bootx64.efi". I think you can instead copy that file (e.g. from within a booted OS) to \efi\microsoft\boot and rename it as bootmgfw.efi, and also rename cdboot.efi in that folder to cdboot.efi.bak

A good video, but I would like to point out one minor detail. You hint in the video that a big disk using MBR has to be split up in partitions less than 2TB in size each. It's worse than that: you simply can not address sectors beyond 2TB, so you can only use the first 2TB of the disk.
@zinsy23
2 жыл бұрын
Yes exactly! Another detail worth noting is that the bytes per sector also determines the limit, so if you have a hard drive with 4,096 bytes per sector rather than 512, you can technically have up to 16 TB on MBR, and would be able to go beyond the 2 TB limit in that case! MBR or GPT determines the number of addressable sectors, and that multiplied by the bytes per sector, will determine the actual limitation of addressable storage itself. That's why GPT's limitation is approximately 9.4 billion terabytes, but that's with 512 byte sectors. 4,096 byte sectors could be about eight times that theoretically! There's a lot of little intricacies to this.

A more reliable method is right after boot to run `dmesg | grep -i efi` and look at the output. The first line will usually indicate both that it *is* efi and the EFI version and vendor in the case that it's an EFI system (usually will be "EFI v2.xx by American Megatrends" or similar).

Great video and indeed a confusing subject but very well explained !. Whenever I have a new drive and want to use it then I use a live linux distro on a usb, go to the live session and run partition editor (gparted mostly) to enable GPT on it. MBR has a limit of 4 primary partitions and beyond that you have to configure the extended partition (that is the total size of the drive(s) after the primary partitions) and then devide, if needed, the extended partition(s) into logical volumes (up to 2TB each). GPT has a limitation, i think, of 128 partitions and does not have to be flagged as primary or extended or has a size constraint (well maybe in the very very extreme big sizes).

UEFI isn't really that confusing when you look deeper, but when you think of UEFI as a BIOS replacement, it screws with your mind, as you feel the MBR way of one bootloader in magical space is the way, and that UEFI is only for pretty graphics and 2+TB drives. This is unfortunately because of the Windows-focused PC world where we don't need to deal with multiboot anyways due to the fact that most of us just have Windows installed, so it's not something to mention since one wouldn't notice that unless they dual boot. To many it's just install Windows, and done. They don't realize that UEFI is a completely different beast from the primitive BIOS, like Coreboot. BIOS is in no way that similar to the UEFI and both are quite radically different from one another, it's just that UEFI does have a compatibility mode to boot like a BIOS and that many imported BIOS GUIs to UEFI instead of taking advantage of UEFI. As a result, you get Linux users going "fuck UEFI," when UEFI, like ACPI, is an awesome thing that had some trouble getting set up at first since Linux distros had to adjust to UEFI and make their installers support it and handle it automatically.

One of the main reasons for UEFI is Secure Boot, not to make the BIOS pretty, who cares about that? You are correct GPT is nothing to do with UEFI, it existed longed before UEFI. Yes modern secure boot systems usually use both UEFI and GPT. During a new install Windows 10 defaults to using GPT partitions with UEFI BIOS's. If you go into the BIOS, turn Secure Boot off, turn off UEFI to give you Legacy BIOS and then initialize the disk as MBR, you can often install Windows 10 like we use to do with old BIOS's, it then only creates 2 partitions (system and boot), instead of 4 partitions (system, boot, MRP, EFI). Some UEFI BIOS's do not support Legacy BIOS at all. When Windows 10 boot gets totally screwed up, it is much easier to fix yourself when using Legacy BIOS. Most people do not understand the EFI partition! I think only the operating system understands this for the Secure Boot feature. Often Windows 10 Startup Repair fails to fix Windows 10 boot issues, it sometimes even refuses to run at all. But using Legacy BIOS and MBR partitions you can usually fix the booting issues in Windows 10. Some recent UEFI BIOS's have had issues with Windows 10 compatibility, Microsoft blame OEM Manufacturers, Manufacturers blame Microsoft. Recent Dell Latitude laptops for example have ended up with 23 BIOS revisions to work correctly. So in my humble opinion, Secure Boot and UEFI BIOS has become a pain in the arse! I hate the damn thing all together.

Thanks for a good video on UEFI. Up to now, my impression on UEFI was, that it was a Microsoft feature to block other systems to be installed on that PC. My PCs are all old, so I only experienced the BIOS, however my Sandy-bridge i5 laptop from Dec 2011 supports the mouse too on its BIOS. Since I plan to build a Ryzen PC, I have a number of questions about UEFI: - What is the real advantage of UEFI vs legacy BIOS for the users, not for Microsoft? - Why is the UEFI boot faster? The disks are the same and that determines for 95% the boot speed. - UEFI seems to need a small boot partition and MBR also supports a boot partition, but by default it uses the unused first sectors of the disk. Is this the real issue, UEFI needs GPT for booting the system and the BIOS needs MBR? - On installing or formatting disks on old PCs, the installer/disk-utility always asks MBR or GPT, so I assume, that is completely independent from BIOS or UEFI? Except maybe for booting? - Why should the graphical interface be for UEFI mode or is it also supported for legacy BIOS mode? We need probably an additional video, that explains the differences in the underlying architectures. Up to know I used MBR and I use ZFS for data and as OS boot file system. I intend to move all 3 HDDs and the SSD to the new system and I expect that Ubuntu will detect the new processor (Phenom II -> Ryzen) and other changed hardware and boot without any change or re-installation. I will ensure that all disk have a copy of the MBR boot loader and I will keep the sequence of connection of the drives the same. Probably I'll stay on legacy BIOS and try to move to UEFI later, if it has any significant advantage.

TLDR is stick to Legacy it will treat you better. UEFI basically gives you fancy graphics on the bootloader, and I personally experienced about a 5-second decrease in boot time moving to UEFI. So past the fancy graphics and saving a couple seconds, that's really all you gain. Really not worth it unless you have to have the latest and greatest. Legacy can do some graphics, but not a full HD wallpaper with special icons for specific operating systems.

I had issues installing grub when I was starting to learn more about linux. That is when I knew I had to check for UEFI boot. Any drive with windows installation normally shows up as two drives, one with UEFI label. It is the one with UEFI label to select while booting. Even if there is no UEFI shown or you select the non UEFI, windows automatically detects UEFI compatibility and switch to UEFI in a normal scenario. My laptop is new but is stuck with legacy BIOS (I don't know why, it's only released last year, curse you HP!). Well, I had no idea I had to run it on GPT and got errors. That is when I knew legacy supports large drives. Also, Linus was not that wrong, he was referring to MBR. GPT is a new way for legacy BIOS. P.S. You can get errors if you try to partition GPT drive in Windows. First, it will give you a warning if you partition during install. If you don't partition during install and does it later, you will soon get BSoD's and such problems. I don't know why this happens. This is the reason I can't run Linux with Windows in my laptop.

I've always had issues when dual booting Windows on UEFI based Grub. The only way I've had success is to use Legacy when doing the Linux installation and the os-prob the windows install into it. Note: I do this with 2 different physical drives. Due to the way Windows now does it's bi-annual upgrades I highly recommend separate drives as it can overwrite the grub bootloader if it is on the same drive. If you want to modify the windows based bootmgr I recommend using EasyBCD (neosmart.net/EasyBCD/) Also, Milage will vary in Windows as it seems like it is constantly changing the way Windows 10 is setup. It is very hit and miss. I believe Windows 1803/1809 switched to favoring UEFI mode and why the setup fails when loading these images in Virtual Machines where 1709 doesn't have an issue. As far as Linus's video, I was disappointed in it, as he didn't mention GPT one time and made it seem like all you need is a UEFI based system, which of course isn't right.

Everyone in the world knows UEFI is used with GPT and BIOS/LEGACY with MBR. We all agree on that... where the destination is not made and where it gets confusing is ... Can you still use BIOS/LEGACY +MBR and Partition a larger than 2TB HD into 2TB multiple partitions with MBR and never have to deal with GPT? and Can all O/S's Support LEGACY BIOS +MBR as such?

love the video .. you explained it well ... butt as a old guy i can tell you the reason alot of how to videos are different and some times wrong is because UEFI standers were never set 10 years ago .. man did some manufacturers make a mess out of it ... my 2007 lenovo k230 has uefi sport .. but it only works for USB / SD "removable" boot drives will not see an UEFI partition on a GPT disk but will see the UEFI partition if it was made on a MBR disk and will add the boot options to the F12 menue , but will not boot to an UEFI boot menu and hase no options to change legacy / Effie .. .. myself even on my kool laptop i have never frond a befit to UEFI ... i have only exasperated hardships with UEFI ... to the extra 5 sec boot time 1. the OS gets locked down, and for programs like GRUB or easyBCD "windows" it will take your ability to boot from a .iso, .img that are on your hard drives. so you cant use a live boot .iso to fix your system.. 2. if for some reason that uefi partition gets deleted , good luck booting or duel booting 'this got better over years' but its a horrible situation, if you encrypt any than 3. sincerity issues , the Ufi gives access to devices to change bios settings , if your concerned about that type of stuff 3. MBR is 100% fixable no madder what you do to it, and backwards sport for older or sensitized OS'es.. neosmart.net/wiki/easybcd/portable-entries/iso-images/ help.ubuntu.com/community/Grub2/ISOBoot

Especially glad to read about the additional 5s, thought I configured something wrong whenever I tried UEFI- and GPT-based installations. Again, the old KISS principle holds: I use compatibility mode, Grub2 and Ext4 on a MBR-formatted SSD to boot into KDE in about three or four seconds now (best time according to systemd-analyze: 1.347s, that’s without BIOS initialisation, but including starting KDM). Ok, not quite KISS. Maybe I'll give UEFI another try someday. [Edited to correct: meant to write legacy mode, wrote compatibility mode]

You are correct that the maximum number that can be written in the partition size field is 2TB, but the start address is similarly limited. This means that MBR cannot support drives over 4 TB-1, and support for drives over 2 TB is not guaranteed (some old systems, especially 32 bit ones, don't expand the data structure size when reading the disk in memory, which can lead to undefined behavior if they try to write logical->physical address translations). Carving the disk into smaller partition sizes doesn't actually help with this limitation.

Years ago this was easily possible using grub ... just edited menu.lst ... boot three different linuxes or windows7 from the grub menu... chainloader was your friend. Grub could also find boot sectors on disk partitions if you had messed up the mbr. UEFI and grub2 are great until the sh1t hits the fan. The easiest rescue seems to be to 'update' from the (linux) installation disk (always have one!) and (multi-)boot will be restored automatically. Only leave in the disk(s) you want to multi-boot if you want to use the bios to control the boot disk/partition.

1. I am a subscriber and I never saw that first UEFI video, so it looks like it wasn't properly presented by YT algorithm and that could be one of the reasons for its low visibility. The other question is why it happened. 2. What I hate about Legacy is that the boot data is saved in some vaguely defined, pre-partition, invisible and inaccessible space, while in UEFI we have EFI partition and it's clear where and what data is there - kinda helps to understand and control it. Also, because of EFI partition, we can have many grubs, on legacy, it's always one and the next one overwrites the previous one. Often there are issues with it, like the grub wasn't properly installed, or the previous boot sequence wasn't properly replaced and so on. What I dislike about UEFI is: it makes things little more complicated for newbies, because firmware vendors don't have a unified interface or ways of setting it. Because of that none of the dual-boot articles mentions even a world about it. So for example, when I was fresh, I had an issue making dual-boot, because my laptop showed some error prompt. The solution was to navigate with arrows to point the proper file in a proper directory in EFI partition to point it to the firmware FROM THAT ERROR SCREEN (not in UEFI settings, there was no way to set it there). Once it was done, the location was remembered and the next boots were successful. On another laptop Windows UEFI partition was used by default and that was all. I had to create a new boot in UEFI settings and point to proper boot files in order to work. I'm sure there are many other ways vendors do that. Also, the naming is confusing. Is it BIOS or UEFI? In my case, I am presented with typical BIOS interface and I can only use keyboard yet the laptop is rather new (3 years) and from top line (Alienware) so detecting UEFI vs. BIOS because of BIOS alike vs. advanced UI is not a good example. It's hard to explain for newbies and it's hard for me to understand how in someone else computer it is done. I will manage it fine when I see it, but helping others remotely is often impossible.

UEFI is also more secure than lagacy, means no one with only physical access to your computer can just insert a bootable USB or CD and boot from that and have a complete access to your data.

What I like the best about UEFI, is that you don't technically need a boot loader. You'll be hard pressed to find a linux distribution, or any other OS (I think) that doesn't use one, but you can set if up yourself and save a couple of milliseconds booting. ;) Other than that it's pretty horrible. GPT of course is great and if I'm not much mistaken you can actually include a MBR and boot from a GTP partitioned drive, even if your old school BIOS doesn't understand GPT. Gosh, I miss the old days...
The biggest benefit of UEFI is its security over BIOS. UEFI can allow only authentic drivers and services to load at boot time, making sure that no malware can be loaded at computer startup. But I wonder if this is only true for Windows .

Sorry, but you're falling in the same kind of error as people with GPT and UEFI (as presented in this video): it is not UEFI what performs security checks in pieces of software as kernels and drivers, it is secure boot who does it. If you disable secure boot you won't get those security checks anymore, even when using UEFI. Finally, that's not only true for Windows, you can have secure boot enabled in Linux distros like Ubuntu, but not in others like Kali (at least at the moment).

So to put it simply in Windows UEFI Boot = GPT Disk formatting Legacy Boot = MBR Disk formatting No mix and match is possible Also in the case of Windows 7, your BIOS must be set to UEFI Hybrid or UEFI with CSM Support to boot into UEFI since Windows 7 still uses a 16 bit mode INT10H call during booting even in UEFI Windows 11 has dropped Legacy boot support completely and will not boot from MBR disks or Legacy boot mode (Workarounds have been found, but none fully functional) Linux can have mixed and matched boot modes, such as GPT with Legacy boot and MBR with UEFI Boot

Your definition of "old computer" is misleading. 5 years "old" in fact is relatively "NEW" computer. I could NOT install large drive as boot drive to my old intel Core 2 Quad system from year 2008, because it did NOT support uefi at all. Also the "old legacy bios" (which is/was the only option available) did not support booting from GPT disk and only MBR -- and yes, I did try (both, to install fresh and even tried GPT disk with already installed OS from another computer, the system reported that there is no bootable drive installed at all). Yes, I could use GPT drives in the system later as data drives, but BIOS refused to boot up from one. And NO -- you can not use big disks with MBR and cut it to 2TB partitions and use it all -- you can only use up to 2TB disk space from the entire 10TB disk when it uses MBR. Yes, it does say there is 8TB more space, but you can not create any more partitions into that space. Tried that also.

Hi Chris, been a lurker for a while and have played and worked with Linux since Slackware was the popular distro. I have a dedicated desktop that has a UEFI bios, and had quite the ordeal in getting Kubuntu 19.10 installed due to issues with the UEFI while trying to partition manually. I finally just let it load onto my SSD only. The boot process seems to act a bit odd and this video helped me to determine why I think that is the case. This is my first time with putting Linux on a box with UEFI. So this is what I see from efibootmgr and I need a little assist to fix: sudo efibootmgr BootCurrent: 0003 Timeout: 1 seconds BootOrder: 0003,000C,0004,0001,0002,0000 Boot0000 Windows Boot Manager Boot0001 Hard Drive Boot0002 CD/DVD Drive Boot0003* ubuntu Boot0004* UEFI: Built-in EFI Shell Boot000C* ubuntu I do not have Windows on here at all, and I don't think I need 2 entries for ubuntu, but am concerned I may break it without a bit of guidance.

Pretty good, could be better. Point: GPT uses a larger data format than MBR which allows it to not only manage a larger drive, but to manage the space more efficiently as well. Compare a hardbound book (GPT) with various font sizes to a smaller pamphlet (MBR) that has more limited font sizes. Analogy breaks down easily, but GPT can have many more file records stored compared to MBR, and with more granularity of information concerning the files (therefore more efficient). Still, UEFI seems like a hack. I keep kicking myself for not learning machine language back when it wasn't that hard on a Commodore 64.

One thing that confused me (and so I ignored it) is that the BIOS on this newest motherboard has two icons for each possible boot device, one plain and one UEFI. (which you can drag and drop to any order, BTW.) So when I was adding another linux OS (I have a bunch) the setup gave me odd choices, only allowing EFI boot (which I have been successfully avoiding for years.) It turned out that the DVD booted different setups according to whether the BIOS was set to boot the EFI-version icon or the plain icon. Not every linux distro setup DVD does this, though.

Marketing is a wonderful thing, it truly is. A new acronym does not make a new animal. Don't get me wrong here, I am not calling anyone out or disagreeing with much of what you have said. I will say this though, they could have skipped the UEFI name and called BIOS it 2.0.. It wouldn't have made any difference, but someone in marketing decided a new name plus all the "new tech" would gear up the geeks and get them excited about the new features (I consider myself in that category, so this is not derogatory). It wasn't to long ago and there just wasn't enough space on a BIOS chip for the UI and clickable menu, lets not forget that it just wasn't conceptualized. The BIOS was intended to be lightweight, init all the devices, let the OS know the properties of said devices, and get the system up and running (it's true purpose after all). That the BIOS has gotten more and more complicated is a product of time and tech. All of the "UEFI" features could easily go into a more classic looking BIOS with a Enable/Disable option or some other easy to use drop-down menu, but hey clickable stuff is cool isn't it? I've spent no small amount of time writing/modifying BIOS code and I can tell you that UEFI is nothing but an addition to "classic BIOS" code. So I find it funny when I read that UEFI is going to replace BIOS, when it's just extra crap (try to keep up with my technical terms) tossed on top what was already there. Support for larger partitions needed to happen certainly, old tech has to make room. Sure there are some new features for security but, the init of devices has not changed one bit. Besides UEFI doesn't just go away when you turn on legacy boot; this is just a simple option enabled or disabled.. And UEFI is not what enables a GUI, the larger space available on a CMOS chip allows that...

(removing the microsoft key isnt an option because the refind loader wont be able to load the bootmgrfw.efi since its signed by microsoft... also if i want to use nvidia driver in combination with secureboot on linux the only way to have it go flawless is by using the shim.efi to load the linux kernel wich is also the one signed by microsoft. also in order to read basicly any fs other dan v/fat/16/32 you wil need efi drivers for that filesystem (most of them you can find in the chameleon bootloader zipfile ) , all of wich ofcource are for efi1.1 , and signed by , to change efi stuff from within windows(re) i reccommend searching for an old (free) version of easyUEFI, since the way to do it from cmd is hopless, certainly compared to the linux tools for the same purpose (efibootmgr and efivars). lastly , uefi , can be extended at your own desire , for my previous motherboard (msi z77a-gd65,) wich had no support for m.2nvme drives , (meaning you could use a pci-e card and it would work but you could not boot from it ) i used efitool and some other stuff following a german blogpost on the topic , and extracting the functionality from a bios update for a newer msi motherboard put it in the latest for mine, flashed it and voila was booting from it... (luckely the msi mobo had a dual bios so i kindof could see if it worked or not risk free)

Does anyone know - if I set up a boot drive w UEFI and system is UEFI mode, can I still read and use my old hardrives as is (that were from 2011)?
