Starting ReactOS installer takes several eternities before blue GUI shows while displaying nothing.
Did not measure more than 8 minutes; how many time it can take due to impatience.
What can help to speed up this process: Disconnecting the SATA cable inside the PC and reconnecting it again before or after something appears on the screen.
The further installation procedure (first part) is progressing successfully.
