From time to time (not always) when booting, Windows sticks for about 15-20 seconds on the initial black boot screen with the logo (right after the BIOS start) before showing the spinning circle under the logo and start booting, i.e. the circle is shown with the delay. On the next boot the circle can be shown right away.
There are no errors in the Event Viewer.
Updates are not installed when the delay happens (I have them installed on demand).
HDD light is off during the delay.
I am new to Windows 8.1, so I wanted to ask whether this is a normal process, or is this something that requires checking?
