    Hello,

    Try repairing boot records first, using these steps:

    1. Start your Windows 10 machine, and quickly shut it down before it reaches or if it is at boot screen. Do this two times repeatedly.

    2. On the third time, Windows 10 will automatically display 'Your PC couldn't start properly' message. Now press Esc key for recovery options.

    3. Then under Choose an option screen, click Troubleshoot option and now click Advanced options option.

    4. Under Advanced options screen, click Command Prompt.

    5. Type following commands one-by-one and press Enter key after each:

    BOOTREC /SCANOS

    BOOTREC /FIXMBR

    BOOTREC /FIXBOOT

    BOOTREC /REBUILDBCD

    6. Close Command Prompt and see if issue is resolved now.

  • Thank you Kapil,

    Sadly I tried what you suggest and it didn't work. And the bootrec /fixboot don't work, it said that the access is denied the others commands are ok.

    There is a way to reinstall windows without losing the product key? I don't care about the files, just don't want to lose the pc.

    regards

  • Create a bootable Windows 10 installation media, then use it to clean install.

    If your computer had been activated before, when re-install system complete, connect to Internet and Windows will be activated automatically. If the computer is not activated before, you need to contact manufacturer support for system reinstall.

    Create installation media here, you need a USB drive whose size bigger than 4GB

  • The documentation is part of the license.  If the PC belonged to a company, the license to the PC also belongs to the company and cannot be transferred to an individual. You will need to purchase a new Windows 10 license.
