Did you just upgrade or install Windows 10 operating system, and when you try to start your computer, you discover that Windows 10 won’t boot?

Many users have reported this error and it turned out that their device either needed to be restored to a previous state or it required to be booted in Safe Mode.

If you have issues booting your system we recommend you try the solutions we detailed for you in this comprehensive guide below, so check them out and see which one suits your particular situation.

How do I fix a Windows 10 PC that doesn’t start up?

1. Confirm that your computer completes the POST process

In many cases where Windows 10 will not boot, the computer may not hand off control of the operating system.

Some users claimed that what helped them in this particular situation was to troubleshoot directly from Safe Mode as we detail in this comprehensive guide.

If you boot your computer and the POST bar fills up completely, then disappears, then it has completed the POST successfully.

2. Disconnect any external devices

Sometimes hardware may interfere with the normal Windows boot process, that’s why sometimes it is recommended that you unplug all your other devices.

Unplug peripherals and gadgets connected to your computers such as a printer, scanner, digital camera, video recorder, USB device, CD/DVD, mp3 player, media card reader, and others.

Keep only your mouse, monitor, and keyboard (if using a desktop PC). Once you do this, unplug the computer from the power outlet on the wall.

You also need to remove the laptop battery, hold the power button down for 10-15 seconds, then plug back the power outlet and restart.

3. Check for the specific error message you get

You can check online about the specific error message you get when Windows 10 is not booting. Such messages include a Blue Screen or Black Screen error, and how to troubleshoot them.

Sometimes these specific errors are generated by corrupted files or out-of-date programs. We recommend you access this article if you want to find out more about how you can fix BSoD.

Check out the ultimate guide about the causes that generate the Blue Screen of Death on your Windows 10.

4. Check your hardware and their connections

If the system refuses to boot completely and you get a blank screen instead, you have plenty of reasons to try and get a bigger picture of the insides of your PC.

That, of course, if you have a desktop PC and if you’re not voiding any warranty in the process. If that’s the case, you should contact the vendor for diagnostics and repair.

If you can open the case without suffering any consequences, here are the main things that you should look at:

  • Hard drive or SSD: If the main booting drive is not connected properly or it’s malfunctioning, you will not get the system to boot. So, check the data and power cables are properly connected at both ends.
  • RAM/ memory modules: Try to detach and reattach the memory modules on the motherboard. Sometimes, a loose connection there may cause this problem.
  • PCI-E modules: Detach and reattach all the PCI-E cards. Although it’s less probable to cause the booting problem, there is a possibility for them to trigger this behavior.

5. Repair your Master Boot Record

There might be the case that your PC is not booting up because it simply doesn’t have a Master Boot Record or it’s corrupted.

This is a major cause for this kind of problem although you should get a Master Boot error in the booting process somewhere.

Anyway, if that’s the case, we’ve got an excellent guide on what to do if the Master Boot Record is missing.
