    After updating the BIOS, the system won't boot. The message System is booting appears and in a moment the laptop starts over and over again. When he wants to go into recovery, BkueScreen crashes. I want this system to work and the files and programs on it, so I do not want to reinstall the system.

    Try to switch the SATA controller mode from AHCI to IDE / Compatibility in the BIOS.

    Restore default settings in the BIOS.
    If you have the original system (you did not install the system yourself using other settings in the BIOS), turn off "legacy support" (Boot tab).

    WojtasDJ I do not know how the system was installed before.

    Now I just want to restart the system. So I have to choose Windows 7 and then load default settings? And should the system start? Because I have already updated to version 40.

    Don't you remember what system you had?

    The method given by WojtasJD will work if it was Win7.

    If Win8 or Win10 -

    and the system should boot - check it.
    If you have the original system - it was not reinstalled on another one

    It works. I had to select Windows 7 first. Then click SAVE. Then Load default setting and SAVE again. Then the system booted up with no problem. Thanks!
