15 Best Linux Bootloaders for Home and Embedded Systems

A bootloader is a small but mandatory software program that allows your CPU to boot your operating system correctly. Bootloaders come in all sorts of variations, each with their trademark features and specific target architecture.

Since Linux powers a wide variety of computer hardware, different types of Linux bootloaders exist. So, it’s quite impossible for many starting Linux users to determine the best Linux boot manager for their application.

That’s why we’ve curated this research-intensive list of 15 widely used bootloaders. Stay with us to discover the best one for your needs.

Best Linux Bootloader Programs


When we talk about low-level system resources like bootloaders and kernels, it’s very easy to get lost into technical details. We tried to avoid such information as much as possible and have only selected bootloaders that can be run on Linux machines. So don’t be alarmed if you don’t find your favorite Windows boot manager in this list.

1. GNU GRUB

  1. Why are you still talking about BURG. It hasn’t been updated since 2013. LILO not since 2016. It’s almost like you googled “bootloader” and gave a recap of everything you found with no context for support or reliability let alone security. BURG isn’t even available in the AUR and the last comment on the repo is 2016. While I’ll acknowledge there are some use Please stop using machines for writing articles (or at the very least check th work) boot leaders are the entry way into people’s entire lives and people trust you to give them reliable information. Be better. 👻

    • Hello Justin, I agree with you. Some of the bootloaders listed here are not actively maintained. However, I have included them for educational purposes only. If any user chooses to use one of these bootloaders, they should verify that the tools are actively maintained. With your input, I have added the notation ‘(Not Maintained Actively)’ next to the applicable bootloader. I hope it will help.
