Since building my PC Windows has always stuck on the spinning circles screen for around 20-30 seconds which is too long for a M.2 I think, the whole boot process into Windows takes around 60 seconds. I have done a full fresh reinstall of Windows 10 but it has the same issue.
I have unplugged all SATA drives which makes booting a little fast but not a whole lot, I have also tried removing all USB devices this makes no different at all.

Anyone else got the same MB running M.2 with similar boot time?
