Hello.
I accidentally put Ubuntu on the wrong hard drive.
Initially, the screw was divided into three sections. Windows is on drive C (it is not needed), but there is a lot of data on the other two logical drives, and they are of interest. I almost did not use the freshly installed ubuntu and immediately turned off as I discovered the problem.
Now I have one large partition for Ubuntu + service partitions (Swap and one more). Screw for 500 gigs, hard drive. Live CD (or rather a flash drive) available.
Tell me what to do.

There are 2 types of people - those who do not make backups yet, and those who already do.
Most likely, nothing will be restored - a lesson for the future, always be careful when working with disks. You can try pulling something with TestDisk from under the livecd.

The most that can help you: an additional screw, a larger one that was damaged, you will back up the recovered data there. newly installed windows. you need a damaged screw, even if there was formatting, anyway. Well, the R-Studio program.
With the help of r-studio, you can recover most of the data (according to experience, there was a similar situation: the erroneous installation of debian on Windows, with partition formatting, was a long time ago ....). Most of the data has been recovered. Especially MP3, AVI, stream files, archives, binaries are more problematic, office documents in part, text files in the majority.
Try it, the program, in a few passes and heuristic analysis, will restore the branches of the old hard drive, there you will choose an acceptable one for yourself, and you will extract the data you need from there!

Get a backup. In case of absence - cry and say goodbye to the data.
Make a full sector-by-sector copy of the disk. In the future, work only with a copy. And consistently try all the software that you find for data recovery. You can start with testdisk, you may be able to restore the partition right away. Even if it succeeds, the data could be corrupted and partially overwritten.
Good reviews about r studio

take out the disk and take it to a service where lost data is recovered.
Of course, you can make fun of it and try to restore everything yourself, but the problem is that returning data when moving from one file system to another is very, very problematic

I have the same problem, I don't know what to do now. My wife's photos were on drive D. And when I installed Ubuntu, everything was demolished and there was one section. Used Ubuntu for about a week. Tomorrow I'll take it to the service center, I hope something will be saved. Although I think it's unlikely ....
