According to device manager, unknown device is not connected.

Elininate the device. Then reboot. If it returns, you probably have a problem as UT noted. So, disable that device in Device Manager. Then reboot. That should keep the BIOS from finding and trying to enable that now defective device.

The BIOS first talks to and enables every device using a system far more complicated that even DOS. An entire bus system talks to every device (even PCI bridges), obtains an ID number, and then tries to setup the device. All this done long before it even tries to boot the OS. Apparently that hardware bus sees some device but cannot initialize it.

So, which unknown device is it that's unknown? Which unknown unknown device should he disable?

And, if it's not connected, and it's unknown, how does the computer know there is a device at all?

Also: "Device" should be a verb.

Do you have a USB keyboard?

I have a laptop which was making similar noises to those you describe and messages about device drivers often appeared.
As the laptop is more or less welded to the desk I have used an external keyboard for some time.
The cable between the keyboard and the laptop had almost worn through where it had become twisted.
When moved, contact was made or broken as the core(s) touched or separated and the 'badunk/badump' noise was issued forth.

References were made to completely differerent systems in your computer. BIOS uses hardware that Windows will see. BIOS gets ID codes from devices "that it sees" to initialize them. Windows uses completely different hardware to know of a device it cannot see; cannot access, connect to, or setup.
