Today, I encountered the following error upon booting Grub:
GNU GRUB version 2.06
Minimal BASH like line editing is supported.For the first word,TAB lists possible device or file completion.Anywhere else TAB lists possible device or file completions.
grub>
Instead of being directed towards the usual graphical interface, I was presented with a CLI, asking me for input. I have tried solving the issue with advice given from geeksforgeeks by executing the following commands:
grub> set root=(hd0,gpt3)
grub> set prefix=(hd0,gpt3)/boot/grub
grub> insmod normal
grub> normal
But after this it throws an error saying `error: jpeg: too many Huffman tables.`
Actually what happened was I was trying to change the background of the gnu grub by gnu customizer app in Ubuntu
