Serious Problem with BIOS after installing W10.

Haven't looked yet although I don't recall seeing any of those fast boot options when I set the power plans up. I'm on a Dell with 8.1 just now and that too hasn't got those options. Maybe because I set the power plans to never sleep or hibernate and I always set lid and power buttons to shutdown fully. Same for critical battery level.

The Dell has super fast boot times from cold (<15secs) something which the Acer running either W8.1 or W10 doesn't come close to matching (about 90 seconds give or take).

DISABLE Quick Boot in the BIOS.

Well you have fast startup enable which more like hybrid between hibernate and shutdown. When you shutdown your pc windows will hibernate the core of system instead of completely shut it down thus make booting much more quickly. But this doesn't apply when you choose restart option because windows completely shut your pc down and then do a real cold boot.

So your pc is perfectly normal, my old acer laptop, which were made to run windows 7, now running windows 8.1 with fast boot enable does the same as your pc.

To avoid fast boot you can hold the shift key when you press shutdown button. This make windows completely shutdown your pc.
Or if you want to permanently disable fast startup you can follow this guide
Fast Startup - Turn On or Off in Windows 8
It's for windows 8 but should be the same with windows 10

I was experiencing this same situation on my Dell Vostro 1000. I can now report that disabling Fast Startup resolved the cold boot-up issue. Thanks

Bear with me... 'cos I know this will not make sense, but this is as it happened.

1/ I was offered an update yesterday and after installing and restarting I didn't see the problem of no BIOS appear again (doing normal shutdowns).

2/ This morning I had major problems with LibreOffice (seems it won't play with W10 on my system) and so I recovered back to a disk image made yesterday which was pre update.


3/ Bizarrely, Windows Update now will not offer that update from yesterday despite me forcing an updates check.

The BIOS continues to now appear. I haven't changed anything in there either.

No explanations for any of that other than "it happened" and I have the pictures to prove it. Today it makes out I'm losing the plot and it appears correctly every time.
