Windows 10 not starting? Several reasons can cause problems when you start Windows 10 for the first time or after an update: Incorrect BIOS settings, external devices, error in your installation, we will make a checklist of the problems to be tested before throwing your computer away. the window. And also solutions to make Windows 10 finally start.

Windows 10 that won’t start is arguably one of the most frustrating things that can happen to you with your computer. Especially if you have just updated, which can give roughly the same feeling as having accidentally pressed the self-destruct button on your keyboard (we reassure you, this key does not exist) .

How to know why Windows 10 won’t start

Relax with hot tea and follow the steps in this checklist. If you still have issues after completing these steps, let us know in the comments so we can work it out!

1. A message, an error code is displayed?

This is the first step to check: error messages and other Windows codes which can be quite cryptic. However, be sure of one thing, you are not the only one who has seen this error message and therefore you can easily find a solution to your problem, by entering the entire message or the error code, and doing a simple Google search. You will then be sure to find out what is wrong and the steps to fix it.

2. Make sure the CD DVD drive is empty

To err is human and this kind of blunder is more common than you might think. Don’t assume any certainties, look inside your CD / DVD drive and remove the CD if there is one.

3. Disconnect all external devices

Some external, and sometimes internal, peripherals can prevent your computer from starting up normally. Start by unplugging all the peripherals of your machine then take a good look at all of its ports. It’s quite easy, indeed to forget an SD card somewhere, or an often very compact dongle. Then restart the computer.

You can repeat it by getting your hands dirty a bit more, and unplugging peripherals inside your computer. The usual suspects are WiFi and Bluetooth network cards on laptops. Try to remove them: they are often easy to access and if necessary you can find detailed dismantling guides on iFixit.

On PC towers, it’s much more convenient: remove all the superfluous, and keep only the essential: your video card. Now try to restart the computer.

4. Complete the hardware check with a troubleshooting tool on USB stick or CD / DVD

There are still some suspects that can mess you up and that you can’t just test by unplugging them. There is RAM, your motherboard, and of course your hard drive. The RAM can be plugged in badly in its socket, of the wrong type / frequency for your motherboard (which can be tolerated by some OS), simply worn out, or rendered unusable for some reason.

From a distance your motherboard may appear to be in good condition (check for dust anyway, and if the fans are running well). But up close, the welds of some components can corrode over time. Finally the hard drive is practically a consumable. It is possible that it has simply reached the end of its life. To test these three elements, we have this all in one troubleshooting tool.

You will need to burn it to a CD / DVD from another computer or put it on a bootable USB stick depending on the case.

5. Check that the problem is not with your BIOS

Alas, not everyone comes up with an error message or code. Sometimes the computer will simply not pass the POST step, and therefore will not boot the partition that is on the hard drive. This could be due to a hardware issue that is preventing the startup tests from completing. Or a bad BIOS setting.

To make sure, press DEL or some other key (usually marked somewhere) to remove the constructor splash screen and see what really happens. You can also go to your BIOS settings and reset everything. Finally in some cases, BIOS update is required. Unfortunately, it is a bit more complicated when your Windows partition does not start, but it is not impossible either.

There are indeed methods to flash your BIOS from a USB key. We will soon put a tutorial online, but in the meantime, you can do this search in Google: BIOS Boot-USB-Stick, followed by your BIOS model.

6. Reset or reinstall Windows 10 on your computer

If you are at this stage, there is no other solution: you may have changed your hard drive, or your RAM, but even if this is not the case, you will definitely need to reinstall or reset (in the best case) Windows. Since you will not have access to Windows, precisely, on your machine, you will have to recover and first burn the Windows 10 ISO from another PC on a CD / DVD, or turn it into a bootable USB stick.

Then simply boot on the volume you have just created. Before everything will erase try to use the Windows troubleshooting tools on the installation disc, you may be able, if it works, to reset Windows 10 and keep your files.
