Hi guys. Can someone tell me how to restore the original default grub?
Was having issues with tiny fonts on the grub screen so used "Grub Customizer" app to change the resolution to my computer's preferred grub resolution + added a bkg pic. Now, however, the grub screen flashes up (still tiny ) then the zorin loading png, then the background pic. So that customizer software messed it all up.
How do undo that and restore the original default grub? PS: I'm brand new to linux so my skills & know-how are minimal.
