Flew windows 10. How to restore?

Question

Hard disks

Hello.
In the evening, I turned off the Lenovo g510 laptop with Windows 10 (license, updated from 8), in the morning I could not turn it on.
When loading, it prompts you to select a keyboard layout, then "search and fix" or turn it off.
Not one of the items in "search and fix" does not help.
"System Restore" gives "To use System Restore, you must specify the installed copy of windows that you want to restore. Restart your computer, select OS, and then System Restore."
"Startup Repair" - "Failed to restore the computer."
"Remove fixes" or "Updates" - "there was a problem."
The command line says x:
"UEFi firmware settings" - BIOS is loaded. The only thing I did there was dropped it, which did not change anything. And changed the boot method from UEFI to Legacy Support - also nothing.
There is a discussion on the microsoft forum, but there about win 8 and it is written extremely incomprehensibly, and judging by the comments it also helped few people.
Tell me what to do?

Answer 1

Judging by the question q771331 , the disk does not work for you. Change the drive and install Windows. There are many recipes for finding out the OEM key for it on the net.

Answer 2

Make an image of a flash drive with the required edition of Windows (Home or Pro)
Start from it and select the update point
Or try to start recovery from it
You can take a CLEAN Windows image from torrents, for example rutracker
In general, it would be nice to check if the disk is seen at all ...
