How To Customize Linux Bootloaders ...

depending on which Linux distribution you use or if you're dual booting another operating system like Windows you might have already seen something like this this is crop and it is a Bootloader for operating systems most Linux distros like Debian Fedora or Ubuntu use crop is their default and yet all of them share the same common thing they are mad ugly so let's fix it ladies and gentlemen welcome to today's video and in fact this is the first real video in 2023 today we're going to take a closer look at bootloaders how you can customize them what you need to be aware of and why some online blog posts are not always that useful right after you hit that like And subscribe button thank you very much so what is up with bootloaders anyway and why are they missing on some distributions okay so first thing they actually are not missing but you might not get a selection menu that's all I'm saying the bootloader is essentially a small program that is saved on a storage device which gets loaded by the UE fee in order to delegate control from it to the operating system or well the kernel most operating systems have a bootloader Windows has its boot manager Apple has or used to have bootax not sure if there is an actual name for the current one and most Linux distros use grav of course there are a lot more and especially on Linux but hold on for a second why did I just say that most operating systems have a bootloader well that's because not every single operating system needs one for example on Evie machines or EFI not quite sure and since its kernel version 3.3 the Linux kernel can boot by itself and as a matter of fact it is actually faster because you strip out an extra process however that being said well it is faster it isn't as robust and if the kernel breaks then good luck right so back again to bootloaders on some operating systems you don't even know it's there on some you notice it when something fails and on some it's just visible by default but why in the world world is it so ugly lightweight yeah that's it they just want to be lightweight AKA fast to load and of course reduce error sources but especially if you use several different operating systems simultaneously and nowadays everything is on an SSD anyway then you should think about customizing it it's like a fresh cup of coffee in the morning you see it and you instantly feel better I'm not gonna lie it is even very easy to do so let's start off with grub now there are several different basic methods like downloading and installing an application called crop customize which can be useful especially when all you want to do is to change the color and Order of food entries but if you want something more then you should look into theming you can download a theme by simply searching for your desktop environment and head on to grab themes FYI it doesn't really matter which desktop environment you use because you can simply install any theme the desktop environment is not even loaded so it does not matter which one you you choose yeah so easy download it throw the downloaded files into the right directory add a line in the graph file and type sudo update grub done now simply reboot and you're greeted with your theme or that would be how it works in an ideal scenario now if you're not seeing any changes yet that there are several different issues that could have happened one of the most common ones is the resolution my monitor for example always had the issue that it didn't use 1440p and it's actually not that easy to enforce since you don't want to break it so here's how to fix it inside grub press C to get into the console or you can just choose it from the menu now depending on the version you're using you can either type vbe info or video info one of these two commands should return something like this now look for your screen resolution and note on everything that stands here then we can simply close the console and boot up our Linux distro now we want to open the terminal open up the crop config file with sudo and uncomment the line to describe underline gfx mode we want to change the resolution here to the one we noted down earlier but be careful do not enter a resolution that is not supported by grub if you do that there is a high chance that you break it alright so let's save our file and update crop and there you go it's fixed another problem that you might experience with grub is that when you are using a distro like Fedora the theme does not get applied and even grab update does not even exist what why not well that's because not every single Linux distribution uses the same versions or operates the same Linux in the context of Open Source operating systems is not equal Linux on Fedora well you can still change everything in the same way like previously we need to update group with the command grab 2 make config minus o slash boot slash corrupt 2 slash grub.com and again just as simple as that but while most Linux distributions use scrub as their default bootloader as with so many other things on Linux there are other options as well the thing about most of these though is that they are not really suited for most users either because they have limitations of putting certain operating systems or they're just not getting maintained anymore heck Lilo or Lilo was once a default yeah it's been a minute what I recommend if you want to switch out crop for something else is berg and while it still is a grub derivative it supports way more customization out of the box its configuration is also mostly similar just differently named I'm leaving some links in the video description down below so check them out if you want to use it and yeah that basically was the whole video well of course I originally wanted to include a lot more boot loaders I simply scrapped it mainly because it was frightening that close to No One uses something else to grow up but hey it just works right if you've enjoyed this video then please make sure to show it with a like a sub or even a comment I'd love to hear from you this will be an exciting Year let me tell you that much but for now all that's left to say is good morning good afternoon or good evening wherever you are I'll see you around foreign
