How to unlock a hard drive with all important data?

Question

Windows

This situation probably only happened to me. In general, today I was sitting at a laptop with a Windows 10 Pro operating system, and when I rebooted into the BIOS and loaded the USB flash drive (operating systems on it), my disk was no longer detected, even Windows PE does not see it! Please, help!
PS: Wrote this question on my old computer.
EDIT #1: I forgot something, in short the C: drive was renamed to the F: drive, is there a program (or LiveCD) that can set any parameters to the drive?
EDIT #2: Kaspersky Rescue Disk 10 has file access 0_0. While I'm dragging all the important files onto the flash drive, I will somehow restore the whole thing (return the hard drive to its previous state)!

Answer 1

Professionals are professionals, and you can do something yourself (the main thing at the same time is to access the disk only for reading, since any write will corrupt some part of your data irreversibly). To do this, I advise you to take any LiveCD / LiveUSB containing a popular package of utilities for all occasions called 2K10 (I have a Multiboot containing as many as 5 different WinPE, from WinXP to Win8, each with its own set of drivers - for any of them your The computer will start normally).
We start from a flash drive (then, in my case, select one of the available WinPEs in the start menu), launch a disk tester, for example, Victoria or something similar (again, strictly for reading!). If the disk is more or less readable and its SMART is not catastrophic, then we launch any partition manager (Acronis Disk Director or Paragon Disk Manager) and observe the presence and health of disk partitions. Since in your case the disk is visible in the BIOS, but not in the OS, we launch one of the partition restorers (there are several of them in the 2K10 package). Further, in case of successful partition recovery, we launch one of the file and folder restorers (there are also many of them), and as we restore, we store it on a third-party medium.
And only if all this fails, and the information from this disk is desperately needed - we prepare a bundle of money and go to the pros.

Answer 2

Take it to data recovery professionals.

Answer 3

so in BIOS this disk is visible or not?
