I am beginner with Linux. I followed that guide to encrypt disk and install Ubuntu 19.10 from USB https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019 I didn't have errors following those steps. These are my partitions in GParted


When I reboot my computer I am offered to type in passphrase. But after I've typed I have only GRUB message that Minimal BASH-like line editing is supported.... Could you please help what can be wrong? It looks like GRUB cannot decrypt partitions... enter image description here

  • @user68186 ls showed me (proc) (hd0) (hd0,gpt5) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) – Dron4K Jun 4 '20 at 6:58

Finally I've resolved that issue. Unfortunately I can't answer what was the root cause. I took another USB drive and performed all steps again from the link in my first post. It works correct now. So it looks like my first USB drive is damaged.


This behavior may occur after entering an incorrect password.
