Add a text before pasphrase boot request

I would like to add a text above the passphrase request to decrypt the disk on startup. At startup I first have to enter the passphrase, then GRUB appears, I’m interested in adding some text in the first “screen”.
Any suggestion?


I’ve never done anything of the sort and I wouldn’t be able to help you either way, but it would probably be helpful to post some details about your system.
What model is your pc? What program did you use to encrypt your disk? What is the program that runs that screen at boot?

Thank you for the reply,
I’m sorry for omited informetion. I have a HP Envy x360 2-in-1 Laptop 15-ew0xxx with EndeavourOS (Gnome 45.5). This is my disk configuration:

My boot partition is 5 or 7 (I’m not sure) and partition 6 is my root (on Btrfs with snapshots) with a luks encription.
This is the first screen that I see when boot my pc (in this case I intentionaly type a wrong passphrase):

After that (and correct passphrase) Grub menu is load.
I would add a text before “Enter passphrase for…”. I think that is a script (or somthing like it) that start before grub to decrypt the disk.
I hope to provide all information

Ah sei italiano lol
Probabilmente devi vedere se ci sono delle impostazioni di configurazione di GRUB che ti consentono di cambiare quel prompt. Io uso systemdboot, quindi non saprei aiutarti. Dai un’occhiata su Archwiki magari.


You probably have to check whether there are any settings in GRUB’s config that allow you to change that prompt. I use systemdboot, so I cannot help you. Try to look it up on Archwiki though.
