How to recover data after reinstalling Windows?

Question

Hard disks

Good people help! This morning I woke up and turned on my laptop and was pleasantly surprised. The BIOS booted up instead of WIndows (a month ago there was the same story, I went to the workshop and for 4k they restored the data and reinstalled Windows). This time I decided to reinstall Windu myself, since I don’t upload 4k every month. Installed Windows, but the data - tyutyu. Downloaded EaseUS Data Recovery, looking for files. Everything is good. But the names of these files are completely random and a simple set of Latin letters, plus they are not structured by folders as they were originally.
Please recommend a good data recovery program. I beg you, I risk being in the trash in such situations, because 90% of the work data and only 10% of the courses

How to recover data after reinstalling Windows?

No way! This must be done prior to reinstallation . And now, presumably, a significant part of your data is overwritten by the Windows installation files. It's amazing that you had the same story a month ago - and it didn't teach you anything, especially since you have 90% of the work data .
But since they asked, I'll have to help, although I'm not an expert in data recovery. I'll tell you how I would try to solve this problem. Perhaps the part that is not overwritten can be obtained. In order not to install rescue software on your computer (after all, it can also overwrite something), you need to start the computer from some repair and recovery LiveDVD or LiveUSB. This is something like Hiren`s BootCD, Sergey Strelts' disks or my favorite MultiBoot. There are usually several (up to a dozen) programs for recovering deleted files - try them all in turn. Personally, I fell in love with R.Saver - although it is not designed for complex cases, it can save the nesting structure of files and folders, and is very easy to use.
Always set the saving of the found to an externally connected flash drive or external HDD, and in no case to the processed disk itself!

This is fine. The file system is designed in such a way that when files are deleted, the first letters and folder structure are lost.
Rejoice if critical files are restored whole, and not just pieces of them.
It makes no sense to advise the program especially, almost all work in approximately the same way.
If you want to save the maximum - contact the service, let them restore at least the files.

Answer 3

Try R-Studio, literally last week I recovered files from a deleted partition on a disk (for some reason the partition itself was not restored), the file structure is preserved.
Available on the Sagittarius boot disk:

First of all, you need to stop using the computer and boot from this disk. Windows actively writes to the disk, overwriting the files you need.
Those files that were overwritten during the reinstallation of the OS cannot be returned.

Connect the disk to another Windows computer, download R.saver https://rlab.ru/tools/rsaver.html to another disk and do a full scan of your disk. Be sure to save the result to another disk as well.
