Guys, I managed to recover my partitions. I used test disk to write the detected efi partition which was of 500MiB. The gpt partition table backup uses 33 sectors to I created second partition starting from where the previous ended to totalsectors-33. I was able to luksDump the header after this and successfully decrypt and mount my device. I had to grub-install and now my system is up and running. Thank you so much everyone for their help and their kind words.

I did test disk on the drive and recoverd my boot partition. Seems like the data hasn’t been touched. The problem now is recovering the luks header. As my root partiton was encrypted with luks.

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?

Mapping copy and paste to different modifer helped for me. Alt or Mod1 + c or v is easy to reach.

Using firefox + arkenfox user.js and addtional changes like disabling deletion of cookies per site took a lot of effort. Now I just use brave.
