It seems like you're trying to express that it takes about five seconds, but you're unsure. Windows can feel slow when starting up.
I'm using an older version without Windows 8/8.1, which affects boot speed. From the power button to the desktop, it usually takes less than 30 seconds—around 20 seconds.
On my laptop it takes roughly 2.8 seconds, then about 4 to 5 minutes, and finally another 30 minutes to ensure the internet and system are ready without being too slow.
