Wrong Ubuntu installation = lost data???!!!

[John::::]

Hi all.
I have a pretty big problem .. I wanted to install Ubuntu installation I chose the wrong partition. I have a laptop in it 640GB drive that was partitioned to C: \ and D: \ .. When installing Ubuntu I chose D: \ and then created a partition 445Gb, because I thought that Ubuntu will be installed on the remaining 15GB, which is the D: \ drive reserved ... But unfortunately, the opposite was true ... so now I only see windows in the C: \ drive, which has 160Gb and the rest I do not see at all ... Unfortunately, I'm on it "rest" all data .. school work (drawings in AutoCAD and similar important files) .. need to study at the university = ((... please help me ... what can I do to change returned? Many thanks for any valuable advice!

Connect your HDD to another Machine & scan with R-studio you will get Data not sure all because u overwrite some Data.

Prepare to loose folder structure at some point.

i really wonder why don`t u guys use VM OS for testing!!!!

So there is no way to fix it without having to disassemble the laptop?? Omg .. I'm worried that it'll break even more .. R-Studio trying now .. It scans was about 4 hours and it's still not finished. I've heard of the company Data Recovery .. so I'll probably just have to put there = (
If I could turn back time ....

Some other advice please?

to einstein9:
Until then, I broke it, I discovered the VM OS = / damn...

If it's not too late, and you haven't disassembled your laptop, you may use the network capabilities of R-Studio: Emergency Data Recovery over Network.

i never trust linux for partitioning or allowing it to do so. it always meddles with rest of the system..
i always do it on seperate hdd or vm..

however the chances of gaining ur data back is very thin and slight i have been through similar situation.. wish it could improve for u
