Partition table recovery?

Question

Iron

Good day to all. A very unpleasant problem appeared - the partition table on the screw was covered. It was something like this. There were 4 partitions on the netbook - two NTFS for Windows + ext4 + swap for Linux. Linux has long been forgotten and overwritten by the bootloader. It was necessary to reformat the section with Linux into something readable under Windows. I tried to get on the screw with a standard utility from the administration of Windows. The utility found a 20-gigabyte partition with an incomprehensible (or unallocated?) fs. Naturally, there was an assumption that this is the partition with linux (it was just a 20-gigabyte one). I formatted it from under this utility to NTFS, and then the administration revealed that there was a 200 terabyte partition that had appeared from somewhere else (which is absurd in itself). Refreshing hard drives generally led to a crash. Reboot - Windows does not boot (swears at some kind of corrupted file). BUT! The boot area itself is intact. The natural thought is to reinstall. Booting from a flash drive (via Grub4Dos), the installer sees the hard disk but does not see partitions and does not offer to format it. Tried booting Xubuntu from live - same thing. I tried the PartedMagic distro. It has the following situation:
- GParted does not show partitions, it throws errors when trying to restore
- the system itself sees two partitions marked up by NTFS, with data! Thumbnails of the same pictures are shown. But for some reason it is not possible to open the file itself, as well as merge it onto a backup over the network.
- the system also sees two more unallocated partitions - one per kilobyte, one per 200 gigs. Physically, there is not so much space on the screw.
Actually the question is - how can you try to restore all this? Or at least merge the data from the screw to format it?

Answer 1

Well, first of all: what kind of errors does gparted throw? Secondly: testdisk to help, boot from libsd ubunta or similar, install testdisk and man-linux.ru/notes/solve/testdisk/ here is a quick guide. Good luck.

Answer 2

If you need data, then I advise you to use R-studio and restore the necessary data, and then install Windows on a new one. There is another option with partition recovery - this is supported by Acronis Disk Director, there are also utilities from Hiren's Boot CD - PartitionRecovery, Smart Partition Recovery.
