    What do you mean by "Till was done". How do you know it was done? What message did it give you to say it was done?

    I think it tries to boot windows but is not possible from usb. Always goes back to the screen where is button for restart or cancel and it went back to windows advance options. If i click restart it always come up with no bootable device

    >>>Maybe 4 times>>>it went back to windows advance options. If i click restart it always come up with no bootable device>>>

    Maybe 4 times??? Are you sure that you clicked "repair my computer" 4 times in a row after each time came up with no-bootable device?

    >>>>I had windows update and laptop got blue screen of death. After this my bios can't detect any m.2, any ssd or hdd, not even dvd-rom. I assume somethings happen with bios?>>>

    Please try it at least 3 times in a row with both internal HDD & m.2 drives connected. Just like it was before the problems first started after the Windows update.

    Immediately after each 'repair my computer' attempt has finished and before re-starting, there should be a drop-down log that specifies which operations were successful and which operations failed. Please take note of each log because the repairs may be incremental with each 'repair my computer' attempt until there are no failures.

    Is it possible to downgrade bios?

    Yes but more complicated than when you finally were able to install 1.19 from 1.17. Do you remember the step-by-step procedure you used to install 1.19? If so, please post each step and we'll try to give you additional steps needed to downgrade.

    I took out m.2 and use adapter to connect via usb. Boot up cmd from this m.2. I had bios in flash stick. So in cmd found that bios and installed.

    Did you buy this new, refurbished or used? Do you recall if mainboard was ever replaced?
