If I try to do this I get an error: # grub2-editenv - set menu_auto_hide=1 grub2-editenv: error: environment block too small.
What the issue here ?
Perhaps /boot/grub2/grubenv is corrupted and grub2-editenv is not very good at reporting errors. This happens when the file was accidentally truncated. Does it have 1024-byte size?
If it does not, back up the file and reinitilize it with "grub2-editenv - create" and then insert the original values with "grub2-editenv - set ...". If you don't have UEFI system, you will need to reistall grub in MBR to locate the new file's position on a block device and write the position into the newly installed loader.
