How to edit ventoy_grub.cfg

[0x6A7232]

Is there any way to amend ventoy_grub.cfg from within the grub menu, or do I need boot some OS first?

Such a feature would be useful.

Any grub entry can be edited IIRC.  Just press 'e' on the menu entry you'd like to alter.  Or am I missing something here?

 
If I get to the grub> prompt I can run

grub> ls (hd0,gpt1)/ventoy/ventoy_grub.cfg

and this shows

ventoy_grub.cfg

but I don't see any way to edit it. Is there a way?

You can manually enter the lines one at a time.  You can display a file's contents with

Code:

cat (hd0,gpt1)/ventoy/ventoy_grub.cfg

.  You can also use redirects with cat to edit files, but it will overwrite them if they exist!  So you'd want to display it first, then edit it.  See here: https://www.fosslinux.com/20889/how-to-c...rminal.htm

So, probably you'd want to make a backup (if cp doesn't work, perhaps redirect with

Code:

cat (hd0,gpt1)/ventoy/ventoy_grub.cfg > (hd0,gpt1)/ventoy/ventoy_grub.cfg.bk

  -- this would output the file but instead of the display, you redirect it ( > ) to a new file.  Then you can play with overwriting ventoy_grub.cfg.

Honestly much easier to boot another OS and use a normal text editor, though.  Why can't you do that?
