GRUB is confusing

posted 6 days ago

hello,

I don’t know if this is the right place to ask this question but could someone explain me how a UEFI system boots, I couldn’t find a guide online. I want to know because I don’t understand certain GRUB commands and how it get installed.

I just copy paste commands from Arch wiki and it just magically works without me knowing anything about it.

all the different distros use different grub command parameter and it’s so confusing. eg, Arch and Gentoo.

Arch command: grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=GRUB Gentoo command: grub-install --efi-directory=/efi

why both command is different? exactly where does grub gets installed?

sorry if this is a naive question but i really don’t understnad GRUB.

Yes, x86 legacy is really confusing. Especially if you are going to write your own kernel or bootloader.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
