Now, before you start rolling your eyes and muttering under your breath about how this is old news or not worth the effort, let me just say one thing: it’s actually pretty damn easy to do!

To kick things off, what a UEFI bootloader even is. In case you haven’t been paying attention (and who can blame you?), UEFI stands for Unified Extensible Firmware Interface basically, it’s the new standard for firmware on modern computers. And while that might sound like a bunch of jargon to some of you, trust me when I say that this is important stuff!

So why should we care about UEFI bootloaders specifically? Well, for starters, they allow us to load operating systems and other software directly from the firmware itself. This can be incredibly useful in a number of different scenarios whether you’re trying to run an embedded system with limited resources or just want to speed up your boot times by skipping over some of the more time-consuming steps involved in traditional booting methods.

But enough talk, let’s get down to business! Here are the basic steps for creating a simple UEFI bootloader on ARM64:

1. Write your code using any programming language you like (we recommend C or Assembly).
2. Compile and link your code into an executable binary file.
3. Create a FAT partition with at least one empty sector that will be used to store the bootloader.
4. Copy the binary file onto the FAT partition in the correct location (usually the first sector of the partition).
5. Configure your UEFI firmware to load the bootloader instead of the default operating system or boot manager.
6. Reboot and enjoy!

Now, I know what you’re thinking “This sounds great and all, but how do we actually write this code?” We’ve got a handy-dandy tutorial that will walk you through every step of the process. And if you run into any issues along the way, don’t hesitate to reach out to us for help we’re always here to lend a hand (or two)!
