Windows 10: Win 10 does not boot after update
Win 10 does not boot after update
My PC (win 10 pro 64bit) never boots after any update. 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. That nonsense started with the anniversary update a month or so ago.
I have to turn the PC off and on and go through the BIOS setup until it finally finishes booting.
After that it boots every time until after the next update.
Can someone give me any advice?
I ran that sfc /scannow thingy but it did not yield any results.
As to the HD led, it flickers irregularly, sometimes it's bright for a second or two and then it goes back to flickering. Looks like it's doing something meaningful but heaven knows what.
It happened to me too. The solution for me was "disable fast Startup"
Fast Startup - Turn On or Off in Windows 10 - Windows 10 Forums
Why You Might Want to Disable Fast Startup
Sounds awesome, right? Well, it is. But Fast Startup also has its problems, so you should take the following caveats into consideration before enabling it:
- When Fast Startup is enabled, your computer doesn’t perform a regular shut down. Since applying new system updates often requires a shutdown, you may not be able to apply updates and turn your computer off. Restart is unaffected, though, so it still performs a full cold shutdown and restart of your system. If a shutdown doesn’t apply your updates, a restart still will.
- Fast Startup can interfere slightly with encrypted disk images. 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. The solution for this is just to manually dismount your encrypted drives before shutting down, but it is something to be aware of. (This doesn’t affect the full disk encryption feature of TrueCrypt, just disk images. And BitLocker users shouldn’t be affected.)
- Systems that don’t support hibernation won’t support Fast Startup either. Some devices just don’t play well with hibernation. You’ll have to experiment with it to see whether your devices respond well or not.
- When you shut down a computer with Fast Startup enabled, Windows locks down the Windows hard disk. You won’t be able to access it from other operating systems if you have your computer configured to dual-boot. 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. If you’re dual booting, it’s best not to use Fast Startup or Hibernation at all.
- Depending on your system, you may not be able to access BIOS/UEFI settings when you shut down a computer with Fast Startup enabled. When a computer hibernates, it does not enter a fully powered down mode. Some versions of BIOS/UEFI work with a system in hibernation and some do not. If yours doesn’t, you can always restart the computer to access BIOS, since the restart cycle will still perform a full shutdown.
I have turned off fast startup.
Waiting to see what happens next time an update runs.
Do you have another hard disk having an active partition connected since that can confuse and delay the boot process?
Well, yes indeed, I do have a back-up HD installed that still has the system installed.
But the regular everyday boot is fine, just not after an update.
That disk might well have another active partition. You can use MiniTool Partition Wizard to change it to inactive. Worth a try?
I'll do that, thanks a lot.
Were you able to get this resolved? I'm having the same issue.
I don't know yet. I may not have had an update in the meantime.
I had no problems with Windows 10 start times but since the Anniversary update, boot time is just under 3 minutes. Any ideas to what to look into for the cause?
I am using an NVME drive and used to get a 10 second boot time, but after the AU update its nearly 50 seconds. I haven't added any more programs to startup, so why is this happening. Would like to know if there is a fix. Thanks
Upgraded to win 10 from win 7 online and there was an automatic update to win 10 a few days ago and the next time i restarted the desktop I am now stuck in a bootloop

system restore does not work.......
Just ran WU today with 3 updates on 10 TP in VMware player, the updates were stuck at 66% for ages then completed and said a restart was scheduled. so I restarted straight away.
After the restart the screen said configuring Windows with...
I just did an update, it had one Windows defender update and and a KB something
it downloaded, installed and asked me to reboot.
I did this and it did the 20%, 30% thing before restart, it shut down and restarted
