Unallocated drive after installing windows

[guitarguy999]

So i installed windows 10 over ubuntu 18 on my primary drive. now windows is showing my 2tb drive as unallocated. I loaded up ubuntu on a usb stick, and ubuntu is showing is also as unallocated, and windows reserved. can someone please tell me what has happened?

You are not being clear on your situation. What I read is that you installed windows 10 onto a drive on which you previously had Ubuntu thus overwriting completely the Ubuntu install. What do you expect to see on the 2TB drive? What was on it previously, a data partition of what filesystem type? Was it used solely for windows or for Ubuntu or for both? Maybe some more details as well as answers to these questions would help. Try booting the Ubuntu usb and from a terminal run each of the commands below consecutively, hit the Enter key after each and post the output here.


sudo parted -l
sudo fdisk -l
df -h

THe first two commands, that is a Lower Case Letter L in the command.

yes, I installed windows 10 over ubuntu completely, and I was expecting to see my backup data from the 2tb drive. Prior to this install I was using only ubuntu, and I honestly cant remember which filesystem type I was using for the 2tb backup drive. find and mount found nothing, and right now im running MiniTool partition recovery

here is a picture of the current status

The output you posted only shows a windows partition of 16MB in size. I expect you will need to use some recovery software to find any data on that drive. If you don't have success with the software you are now using, you might try testdisk to recover.

[guitarguy999]

here is a screenshot of a completed scan.

i see "my backup".

i really dont understand all these other file systems especially the NTFS that has a used size of 162.92gb.

i think i will clone the drive before doing anything at all.

can someone please explain to me how that math adds up. i see a 1.82TB drive (disk 1, GPT), then it says 346gb unallocated, then 346.1gb used then 237.9gb unallocated, then my backup (ext4) 1838GB.

The 1838GB with 45% being used and also being ext4 looks exactly like what i lost
