Decryption 14.11

I wanted to decrypt my entire installation of Parrot 4.11. I have problems with booting and I wanted to reinstall grub. It seems impossible with encrypted volume.
Is it possible or I have to reinstall?


  • ParrotOS iso in use:

  • Application used for flashing the iso:

  • Logs/Terminal output (use pastebin or similar services):

  • Screenshots:

Hi. What kind of problems do you have with booting?

Many thanks for replying, now I just posted the full question

Upon booting I see:
Welcome to GRUB and then error: unknown filesystem and the prompt “grub rescue>”
In booting I have legacy support with UEFI priority and disabled fast boot
ls shows (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)
insmod normal gives error: unknown filesystem. I think the problem could be the encrypted installation but I do not know how to solve it.

Weird. Have you already tried to see some guide? grubrescue - While restarting it shows unknown filesystem error in grub - Ask Ubuntu
