Edit: I was able to recover my partitions by creating new partition starting and ending with same exact sectors.
I was copying files from my previous installation to my new Gentoo installation. After I was done. I ran wipefs on /dev/nvme0n1 thinking it is my old nvme drive which is connected through usb. I am in disbelief. Lost all of my configuration files. My perfect installation of gentoo. Just gone. How do I never make such mistake again? Thankfully I had backup of passwords file. Rest is gone. I am sad.
For not making the mistake again? Check critical commands twice.
Also, you can undo wipefs
I’ve recovered my boot partition but my other partition was formatted with luks. The boot partition is working and not throwing any errors. How can I restore the luksheader? Is it even possible?
