I have a situation where i ended up overwriting my main ssd of the workstation. Below is the chrnological order in which the system-partitions/ file-systems were created.

PROBLEM BACKGROUND/HISTORY

GPT partition with 0%-33% , 33% to 66% and 66% to 100% partitions all btrfs type. some important data was stored in this partitions ( from here on refered to as the data
I accidentally overwrote the whole disk with a new partion table and partitions , (2 to 3 times :( ) each partiton of 0 to 3% and 4% to 100% of GPT type and of FAT32 and ext4 file-systems respectively LiteBlue.
ISSUE:

With the above issue at hand i am trying to restore back to GPT - btrfs partitions mentioned in point "1" above

After initial research i am trying to use the testdisk software to restore back the deleted partions.

However upon selecting the particular partion to restore as listed below.

TestDisk can't list files from btfs filesystem but if you think it's a partition to recover, set the partition to P(rimary).
Once it's OK, go on next screen, choose Write, confirm, Quit and restart your computer.
