Grub found non-existent partitions and the system stopped booting

Two days or so ago, grub started finding the non-existent partitions, where is none. Grub commands are also takes A LOT of time to complete (3+ mins or so). Today I couldn’t boot into my system at all, and had to go through the grub restore guide. Here’s output of grub-mkconfig -o /boot/grub/grub.cfg from there:

[manjaro /]# grub-mkconfig -o /boot/grub/grub.cfg

I’m not yet sure if I’ll be able to boot into my system this time, but I guess it’s related.

Nope, it doesn’t boots. It hangs up on a motherboard creator logo before the grub. I have no idea how to restore on this point, seems like timeshift also is not an option. Output from timeshift --restore:

[manjaro /]# timeshift --restore

Select backup device:

Num    Device  Size  Type  Label

Enter device name or number (a=Abort): a
Aborted.

I also must note, that I made a manual chroot, since manjaro-chroot -a throw an error ==> ERROR: No Linux partitions detected!

Welcome to Manjaro! :smiling_face_with_three_hearts:

  1. Please read the information behind this link. It will help you to post necessary information. [HowTo] Provide System Information
  2. Please press the three dots below your post and then press the :pencil2:
  • If you give us information about your system, we can see what we’re talking about and make better suggestions.
  • You can do this by using inxi in a terminal or in console.
inxi --admin --verbosity=7 --filter --no-host --width
  • Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
  • Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.
  1. Copy the output from inxi (including the command) and paste it into your post.
  • To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.
    (Wisdom lies in reading :wink: )

May be your hardware has a problem ?

  • Replug all connections of motherboard / devices ?

Here’s an output from inxi:

No, I don’t think it’s a hardware problem, since I can mount my partition from a live-CD

My grub.cfg weights more than 10MiB, is it normal? I mean, it has TONS of recurring non-existent partitions

I started having a similar problem regards multiple entries for Manjaro. As far as I can figure out these are timeshift snapshots being seen as multiple OS’s.

I’ve managed to boot into my system. I’ve made so by removing os-prober in grub settings (setting the GRUB_DISABLE_OS_PROBER in /etc/default/grub to true) and running update-grub in a chroot from live-cd. But that actually doesn’t seem like the right solution.

In my case my system boots just fine. It just irritates me that the grub is screwed up.

I hope anyone finds out what to do with that bug, or at least will tell me, to which repo it’s better to be reported. i don’t feel “safe” without permission to my timeshifts from grub, but afaik there’s no other way to boot the system at current state of grub’s config
