Dell Zino HD with Windows 8.1

I have a Dell Zino HD and it was working completely fine with Windows 8. Got it updated to Windows 8.1 couple days ago but having some issues in power up. Windows won't load in first attempt. I can see the Windows 8 logo but it won't load (no spinning circle). I have to press and hold the power button to power it down, then power it up again and it will start to load. I was thinking it could be a BIOS issue. Checked on Dell support website but there is no BIOS update for ZINO HD.

Does anyone encounter the same issue?
