Some versions of BIOS/UEFI work with a system in hibernation and some do not. When a computer hibernates, it does not enter a fully powered down mode.

Depending on your system, you may not be able to access BIOS/UEFI settings when you shut down a computer with Fast Startup enabled.

If you’re dual booting, it’s best not to use Fast Startup or Hibernation at all. Even worse, if you boot into another OS and then access or change anything on the hard disk (or partition) that the hibernating Windows installation uses, it can cause corruption. You won’t be able to access it from other operating systems if you have your computer configured to dual-boot.

When you shut down a computer with Fast Startup enabled, Windows locks down the Windows hard disk.

You’ll have to experiment with it to see whether your devices respond well or not. Some devices just don’t play well with hibernation.

Systems that don’t support hibernation won’t support Fast Startup either.

And BitLocker users shouldn’t be affected.) (This doesn’t affect the full disk encryption feature of TrueCrypt, just disk images. The solution for this is just to manually dismount your encrypted drives before shutting down, but it is something to be aware of. Users of encryption programs like TrueCrypt have reported that encrypted drives they had mounted before shutting down their system were automatically remounted when starting back up.

Fast Startup can interfere slightly with encrypted disk images.

If a shutdown doesn’t apply your updates, a restart still will. Restart is unaffected, though, so it still performs a full cold shutdown and restart of your system. Since applying new system updates often requires a shutdown, you may not be able to apply updates and turn your computer off.

When Fast Startup is enabled, your computer doesn’t perform a regular shut down.

But Fast Startup also has its problems, so you should take the following caveats into consideration before enabling it: Why You Might Want to Disable Fast Startup The solution for me was 'disable fast Startup'įast Startup - Turn On or Off in Windows 10 - Windows 10 Forums I have to turn the PC off and on and go through the BIOS setup until it finally finishes booting.Īfter that it boots every time until after the next update.ĮdIt happened to me too. That nonsense started with the anniversary update a month or so ago. I just see a black screen with those little white dots rotating on the lower half of the screen and they do that for hours. My PC (win 10 pro 64bit) never boots after any update.

Windows 10 will not boot after update
