Minimal BASH-like on LUKS-encrypted install after format of secondary SSD

in flag

I can't load ubuntu after I formatted the old SSD I used to have Windows on and that I thought had nothing to do with Ubuntu's boot. The Ubuntu partition is LUKS encrypted and in GRUB I am able to list the following (only the 1TB disk I have ubuntu on is connected as I disconnected the old one):

(proc) (memdisk) (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)

Using ls on the partitions i get the following:

Device hd0: No known filesystem detected - Sector size 512 byte - Total size 976762584 KiB


Partition hd0,gpt1: Filesystem type fat, UUID ______ - Partition start at 1024KiB - Total size 524288 KiB

(hd0,gpt1)/ contains a efi/ folder, which contains ubuntu/ and Boot/. ubuntu/ has a grubx64.efi file in it, while Boot/ contains bootx64.efi.grb and bootx64.efi


Partition hd0,gpt2: Filesystem type ext*, Last modification time _____ UUID ______ - Partition start at 525312 KiB - Total size 1750016 KiB

(hd0,gpt2)/ contains:

lost+found/ (empty), efi/ (empty), grub/

and a lot of linux files which from other guides i tried to look online seem important to restore the boot such as: vmlinuz-6.2.0-20-generic, initrd.img-6.2.0-20-generic, vmlinuz, initrd.img, and others.


Partition hd0,gpt3: No known filesystem detected - Partition start at 2275328KiB - Total size 974486528 KiB

I tried the following:

>set root=(hd0,gpt2)
>set prefix=(hd0,gpt2)/
>linuxefi /vmlinuz-6.2.0-20-generic
>initrdefi /initrd.img-6.2.0-20-generic

And it seems like it starts (black screen with waterfall of white text) while it always gets stuck at

[1.8xxxxx] i915 0000:00:02.0: enabling device (0000 -> 0003)

Do I have to once again bulldozer the system and reinstall everything or am I missing something? Thank you in advance :)

SOLVED! using this guide, in particular the "Via Live Image" part:

  1. created a live Ubuntu USB, booted into it via "Try Ubuntu".

  2. installed boot repair:

    sudo add-apt-repository ppa:yannubuntu/boot-repair

    sudo apt update

    sudo install boot-repair

  3. Using "Disks" I mounted the unmounted partitions of my disk and unlocked the encrypted data partition (Boot-repair could not fix the problem before doing such)

  4. Launched boot-repair and followed its instructions to restore the boot

I will leave this question/answer here as I couldn't find any guide specifically for the scenario I was in, hoping this will be helpful to someone in the future. Boot-repair is a great tool!

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
