So i have been pulling my hair out trying to figure out why my grub theme wasn't changing and i figured out i would leave instructions for future generations
- install grub customizer( sudo apt install grub-customizer)
- I noticed when i was in Grub customizer i went into File>Change environment i had a warning triangle for this "/boot/grub/device.map" so i did "sudo nano mkdir /boot/grub/device.map" to make the file
- Download your theme from your favorite place and put it somewhere you wont delete it
- Extract the compressed file
- go into the grub theme file you just extracted, now its a folder in a folder what you need to do is copy all the files where the images and theme.text file is and put it in the main directory I.E the first folder you go into and delete the old folder so you are left with everything in the single main file
- Close the new folder and compress to a tar.gz file
- go into grub customizer and go to appearance settings and click the blue plus to add a theme, find the tar.gz folder (you may need to select the "all files" option in the bottom left to see it
- Click save
- Go to the terminal and type "sudo update-grub"
- Reboot and enjoy!
To mention im on Deb 12.8 with an encrypted drive
