Can I access BIOS without my LUKS passphrase?


I installed a fresh Manjaro on my Dell XPS 13 with full disk encryption.
When I start my laptop, it directly asks my Luks passphrase and boot to KDE.

  • Question 1 :
    I did not succeed to access to the BIOS/EFI configuration without typing the Luks passphrase. I have to type my passphrase first and press ESC to access EFI configuration. It looks dangerous… If I lost my passphrase, I cannot reinstall a new OS. Is it normal ?

  • Question 2 :
    Sometime, booting is not working. It stay loading with message “DELL / Manjaro”. I have to CTRL+ALT+SUPPR to restart . Any idea why ?
