Hi, @Александр3

Here is a way you may be able to clean install W8.1.

Install W8.1 by creating the Microsoft installation media using another Windows PC...Your notebook came with W8.1 64 bit so make the W8.1 64 bit installation media.

https://www.microsoft.com/en-us/software-download/windows8ISO

Only if you are asked to enter a product key during the installation process, use this generic key.

This is the generic key for W8.1 'standard:'

 334NH-RXG76-64THK-C7CKG-D3VPT

This is the generic key for W8.1 Professional:

XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB

If you had to enter the generic product key, manually change the generic product key to the W8.1 'standard' or Professional key in your PC's BIOS in the PC settings menu.

If you had to enter a key, after you get W8.1 installed, you will need to run the free utility I zipped up and attached below, that will show you show the W8.1 product key in your PC's BIOS.

I have also zipped up and attached below, the Microsoft tool which hopefully will transfer the ISO file to a DVD or usb flash drive so it is bootable.

Then you can install the available drivers and software from your PC's support page.
