the only video that could explain the whole process properly,...thank you so much!!

I love the simple laymen explanation for the non technical person like me to understand. Thank you.

You are making really very intuitive & logical content sir, please keep it up and Thanks for this.

Absolutely perfect explaination. I have been looking for simple details, like about what does MBR have and it's connection to /boot/grub/grub.conf. This video is wow. Thank you thank you.

just beautiful explanation

"jump drive" LOL! Haven't heard that so far, in which part of the world do they use it? Good explanation - how about a detailed explanation of the specific boot sequence for Linux and Windows? Thanks.

Very useful and well explained, thank you

Also, a small BIOS is necessary because you'd want the OS to be opinionated and have its own bootloader. And a small MBR (or now, EFI System Partition) is required because it should only really store the stage 1 bootloader. A partition table such as MBR Partition Table or GUID Partition Table is required for a storage device because every OS will also want to have its own filesystem format, and you may want to have multiple filesystems, but the BIOS/UEFI should not have to know all of them. The reason the MBR Partition Table can only recognize 4 partitions as primary is because it was designed to not use too much of the disk space, at a time when disk space was a premium. So everything is sensible 🙂.

Good presentation. It's really helpful.

Actually, I have studied that The CPU doesn't get instructions from BIOS, in fact when the device resets, all its registers are set to zero except Code Segment(CS) which is set to (0xF000), and Instruction Pointer (IP) set to (0xFFF0), e.g. the first instruction that the CPU has to fetch and execute is already hard coded into the CPU registers by the manufacturers and it points at physical address CS+ IP (0xFFFF0). So the first instruction is fetched from location 0xFFFF0 is a jump instruction that instructs the CPU to jump to the ROM BIOS location.

Thank you for this:)

great explanation 👏

Really like it!

Good job sir!

this was some good video on booting!

I just started but very encouraging.

Are the boot loader and bootstrap loader the same.... because I got a question in my test which had both the options.... Please help someone

Thank you sir

@ Dhananjai Rao, in the video at 8:22 you mention boot loader loads OS into memory...do you mean memory as in RAM?

thamks!

May I ask what is the textbook mentioned on the first slide?

Hey dr.kleiner what does a computer do when you press the start button

GREAT

I owe you cup of coffee thanks

Ty sir

thanks

I am cleared now!

Tqqq sir

Can you provide me the boot loader images that you used in the video?

thank youu

bravo

Sir can you please share the slides so that we can study from it.

Good video but please give this man a glass of water cause mannnn...

Discuss OS for Supercomputers & Distributed OS -- Er. Sunil Pedgaonkar, India, Consulting Engineer (IT), India

Ok, and who came up with this? Why is it done in this specific way and not in other?

It was difficult to focus on the information due to the forced accent. Please try to speak normally

Pretty close.

thank you Sir
