I've had a Kali Linux bootable usb for a long time now. Last night I updated Kali, and shutdown when I went to bed.
I boot up now, and it appears everything is wiped. All files gone. The desktop environment is exactly the same if you had installed Kali for the very first time.
I think that somehow everything was wiped. However, I open gparted, and see that my persistence partition is still on the usb. 50%of the usb used, which was the correct amount before I began the updates.
I believe my files and user are still on the usb, but how would I access them so when I click on the persistence option, it goes back to how it has been prior to the updates.
