Device boots up directly to memtest

Support
1

So, I did an update today. But sadly I lose power in the middle of it and then I can’t boot. So, I followed this post
[HowTo] Recovering from an interrupted update/upgrade

at update-grub i get:

Generating grub configuration file ...

Here’s the output of lsblk --fs , I thought this will be relevant:

NAME   FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS

|-sdb1                                        
`-sdb2

and output from df -Th :

I exit, and rebooted. But, now it boots up to memtest instead to Manjaro. There is no options either.

Sorry in advance if my english is less than ideal.

lsblk should have contained info on filesystems - a response similar to

The lack of info points to filesystem meltdown - the filesystem table has been wiped. This is often caused by powerspikes or flashes in the powerline - a rapid loss and return of power - like a fingersnap.

I hope you have a separate copy of important data, because restoring from this disaster will be difficult even for an expert and it cannot be done using forum support.

Your best way forward is to reinstall the operating system.

If you want to try rescuing data I suggest downloading and using an ISO with the necessary tools.

It will also require some external storage capable of holding the data recovered from the crashed system.

I see. I will try to reinstall. In the meantime, I will just copy everything I can from this live environment into a USB stick. Though, I still have a question before I reinstall. Assuming I keep the current partition arrangements in which /home is in /dev/sda6/ , can I reuse it?

Edit: Thank you in advance.

If indeed the partition table(s) have been wiped, as suggested, then the logical path forward would be to fully install Manjaro from scratch; this would include creating a new GPT partition table and partitions as may be needed.

You could choose the manual partitioning method during install and specify the exact partitions you desire; you could also create a separate /home partition and a dedicated partition for swap.

Regards.

I somehow got it installed as before, assigning the appropriate partition as /home and I have my setup intact (I don’t even need to relogin all of my account in firefox). After that, I immediately run full upgrade again. Anyway, thanks to everyone involved in helping me.
