How to recover an Ext4 partition after formatting it.

[TYGX]

Here is a thing, I want to re-install an OS with a new SSD(M.2) on my NAS(ubuntu). But when I boot in to PE drive(Win PE) the partition initialization comes out, and I hit the inistialize button.

I realize that there is still my old drive(SATA HDD) with Ext4 partition and it's not recognized by the disk manager in Win PE, so it's initialized.

I close the initializing window immediately(within 2s), but I still lost my partition.

I tried to use diskgenius to find the lost partition, but it turns out some kernel partition(about 20s kernel partition, I haven't click the apply button). I am confused, because there are just some videos and photos in the nas old drive.

Is my sequence wrong? Should I do this with linux style software? And how to make it?

I am so sorry for the phone-shot image, but the PE has no internet and I have no capture card :|

Thanks a lot.

Sorry for creating this topic in a wrong part, I am new here. By the way, are you having any solution about this?

testdisk might be able to find the partition and recreate the partition table.

Thank you again, I managed to fix my partition with testdisk, the tool is so damn great that a noob like me could fix this.
