Why UEFI?

UEFI is a replacement for the original BIOS that’s been running computers for almost a quarter of a century. UEFI allows manufacturers to take advantage of the security capabilities of the machines they produce.

Thanks for the clear explanation! mainly here cause of windows 11 but I think it's ridiculous to be forced into using UEFI. The whole point of having a PC is you can do what you want with it.

I had a similar problem on my Acer laptop. My SSD containing Windows failed and I installed a new SSD. I couldn't boot from anything else apart from an unformatted disk with no OS. You have to go into the UEFI and under the "Security" tab, introduce a supervisor password. This will allow you to shut down Secure Boot and load a new OS from a USB stick. As many recent laptops don't have DVD burners or SD Card readers, external USB peripherals won't work apart from a bootable USB stick.

So I understand, I have to pay for the PC and I have to pay for the OS but I´m not allowed to control what I payed for.
I only pay to be controlled by others.

As far as I can say, UEFI is a pile of irritation! Seems to me it's main purpose was to satisfy M$ policy to fight piracy. As long as there would be MoBos options to disable Secure Boot, so you can go with legacy boot too, I wouldn't care about it. Once they would disable that, I would remain happy with any older HW, and under no circumstances would by a New One. The best way to secure your data is an OUTER USB HDD or USB flash drive to keep data there only. Off course, aside off disabling any auto handling of your data by OS, you have to modify a lot (I mean A LOT) of settings in Windows itself. As the best in Windows OS was and remain, is -CUSTOMIZATION. Once this might get substantially reduced or even abandoned with next versions… well, then bye bye anything newer from M$. However, there is one a bit greater evil from UEFI - inability to quickly remove battery from "more sophisticated" laptops and "Smart" Phones!

PS - Aside of all above, love your great work and your website. Thank you for being here and there!

This is for me "BIOS/UEFI" in a nutshell .. Thanks Leo!

I know that I am late to this party, but I have a rather strange situation. My gaming rig died a week ago, and a friend loaned me a Dell OptiPlex 9010 that has been refurbished and has an SSD (C: drive) and a 2 TB HDD, 8 Gb DDR 3 RAM and a Win 10 Pro OS. The PC runs quite well with the I7-3770 CPU, is fast, boots quickly and has been very stable.
I wanted to add a low power draw GPU to it, it has an empty PCI-E slot, so I added an RX 560 AMD card that I have and rebooted the PC.
It doesn't "see" the card at all. I now know that this PC has a Legacy BIOS and needs to be UEFI in order to "see" that GPU. And then the hell began....
I cannot get this PC to accept any of the PowerShell(Admin) commands to partition the OS drive for UEFI boot. Every command results in red errors. mgr2gpt/convert/allowfullos should reconfigure this PCs BIOS but it does not...
I have watched various videos until I am blind and haven't gotten anywhere with this problem.
Can you possibly enlighten me?
Thank you in advance.

If a manufacturer prevents me from booting from any other device than the internal drive, I'm not gonna buy that device - so, I guess the Surface is out for me - shame - was actually considering it - but now I know what to look and ask for when buying a computer - choice of boot device (HDD, CD, USB, etc) and boot order is a MUST on ANY computer - if not possible, it is the manufacturer trying to control you, as the actual user, and NOT to protect you!

bios always had passwords so you can't tinker, but what's inside bios anyway, my pics and documents?
and once somebody is near my pc and wants my data, he can easilly steal my hdds.
so all this talk about uefi bringing security is moot....

Hi Leo! I am glad to find your video to have more understanding of BIOS and UEFI. I don't have any security issue with my laptop at a moment. But, I did read UEFI offer you fast booting than BIOS. I'm still using DELL Laptop Inspiron n4110 series (yeah I know it is quite old). Do you think it is worth it if I convert to UEFI just to get faster boot? Thank you anyway.

[techy_triangle]

You are great person. I love to see your videos.

[changingears]

hi leo. i'm still kind of a noob at computers but was wondering if you could tell me if gpt and mbr boot have anything to do with these two booting systems. is one exclusive to the other? can you use these interchangeably on both, etc? and thanks for your short and digestible tech snippets.

[xgui-studios]

my laptop cant got to uefi with the f2 key and secure boot just make linux more hard to use ....

[Alb_]

I can't understand the difference between legacy and uefi about the boot process and security, you can easily modify boot order in uefi and boot from usb if you like

Hi sir, i have gigabyte motherboard it printed on my board GA-H61M-S1 rev 2.2 uefi bios usb blocker . Problem is that my usb keyboard and mouse work properly but usb storage not connected with my pc... Error show driver not able to install... Please help me

[edgardocrespo]

I have an Asus laptop model Q550LF for home use, and because of this UEFI, I’m, unable to use it for almost a month now. Any suggestions on how to go about it would be very much appreciated.

[philosophers_stone_ish]

As I see it, for most people it makes no difference.for some conservative users it's great.but I'm in the part of people who suffer from that.
They screw up almost all Linux users.

[Ismael-iwtm]

UEFI should be a choice. Don’t take over my computer. Don’t answer questions for me. You don’t know me. It’s just another control of my life. BS My 3 cents. 👏🏾🇺🇸😎

I'lllet you know how MY little 2-year struggle with a BIOS-LOCKED toshiba laptop turns out. I've recently thought up a new plan. I ain't giving up on it, it's too good of a computer to let go to waist in the LAPTOP GRAVEYARD I've got stored under my bed~
