Ubuntu: sudo fdisk -l -u output does not show partitions



Question:

I know this issue is common here, but mine has some specific terms that put me into the corner. So, I booted into liveUsb with Ubuntu, tried changing my partitions with Ubuntu installed to my PC and got the error "can't have overlapping partitions", then it crashed and after I rebooted to liveUSB, whole my hdd was shown as "unallocated". Now, when I am running fdisk -l -u /dev/sda, I get this output:

Output

So, does this mean that all my data is already erased? How is that even possible, when I simply tweaked partitions with ubuntu installed, and did not touch 800GB of other space?


Solution:1

While you were working with your partitions you probably destroyed your partition table, or somehow made it unusable.

You can use a utility like testdisk in a live session to try bringing it back. your data still lives on the disk, so do not write anything on it.
