Manjaro install on my SSD corrupted after trying to expand it in size with a live environment

[jmjro]

I was trying to expand my Manjaro partition, but the KDE partition manager returned with an error and now it says that the partition type is unknown.

Is there any way to recover my data from this partition?

[HowTo] Provide System Information

This tutorial is superseded by this one. Remember all Tutorials are wiki posts that can be edited by TL2 (Trust Level 2) members and above. Welcome to Manjaro! To allow all of us helpful people on this forum TO HELP YOU, we need some basic information about your system. This probably means you described the symptoms of your problem, but now we need some more information to know where the origin of your issue is exactly. Someone else probably linked you to…

Yes

Even inside the live environment it is possible to gather a lot of needed information.

how exactly?

@jmjro

KDE partition manager returned with an error

which one?

Errors during reformmating partitions are usually desastrous. If you have not a backup of data you wish to retrieve you would need professional software to rescue some data. Most likely, very little chance. Take it as lesson and backup your data, next time. I guess you should re-install Manjaro from the scratch.
