There are many great community made GRUB themes to spice up your bootloader before booting into your system proper. Unfortunately, they're spread across multiple sites and it can be difficult to find good ones. As another user told me, the majority of themes on Pling (the largest host of GRUB themes currently) are fairly low effort and can be boring to trawl through. Hence, I decided to put together this page to bring attention to some decent themes I've found around the internet over time. They aren't all absolute masterpieces of course: But they've all at least had a fair amount of effort put into them, with custom backgrounds, fonts, and colours.
And don't forget, themes are extremely easy to customize. Like a theme's layout but prefer a different background? Just replace the image in its folder with one of your own. Don't like the positioning of a theme's elements? Open the theme.txt and change their values. Want a different colour scheme? They're all set by HEX Values, which you can swap out in seconds. You can even convert almost any font to the type GRUB uses with the grub-mkfont command, then change the item_font line in the theme.txt to use it.
GitZip - Download individual folders and files from Github repositories without having to download the entire repo. Asks for a Token, but seems to work without just fine.
GRUB-Tweaks - Multiple guides on various tweaks and additions you can make to further customize, or repair, your GRUB install.
Theme Tutorial and Theme References - Pretty complex, but the best set of information I've managed to find so far. It may be easier to start by taking an existing theme and making edits to it yourself, rather than diving straight in and starting from scratch.
If you like a theme, please do consider giving it a rating on Pling or starring its repo on Github. It's very rare for anyone to rate on Pling and that's half the reason good themes are so hard to find. Plus, it always feels nice to see that people are enjoying the product you created.
