Windows 8.1 deleted all files from the disk during recovery, how to recover?

Question

Windows

Windows stopped loading, and it was somehow strange: when turned on, a blinking cursor appeared on a black screen and that's it. At the same time, grub launched Ubuntu normally, went into ntfs partitions from it, all the files were in place. An attempt to restore from the disk did not give results, a chkdsk check showed that everything was fine. In general, I had to install it on a new one, while the disk was not formatted, because. a lot of useful information. After installation, it turned out that everything was fucked up. What programs to use for recovery?
