Windows 10 boot issue Fixed or failed to start Solution

Few problems on your PC are as frustrating as finding yourself in the position that your Windows 10 boot not working properly. When the system is not even able to start, it is difficult to locate the source of the problem to be able to solve it, so in this article we are going to tell you what you can do if your Windows 10 does not start on your PC.

The problems that can lead to a Windows PC not booting can be many and very different: from an Overclock problem to the hard drive having passed away. In those cases it is usually easy to detect, especially if you have been “touching” something (if you were trying to overclock and the system does not start, then surely it has to do with that), but the problem comes when the PC does not start suddenly and without having apparently touched anything .

Windows 10 Boot issue, let’s go to safe mode

The most obvious solution when Windows won’t boot is to enter safe mode. It is an alternative boot scheme that starts the PC with the minimum necessary software to avoid possible errors. The most bizarre thing about this is that there are times when just starting Windows in safe mode once and restarting, it starts up normally. Windows stuff.

This is important since if we can enter safe mode the options to recover the system multiply, since we can access MSDOS with administrator privileges for example and launch for example:

• SFC / scannow
• chkdsk / f / r

So at least we make sure that the main thing that is the HDD is safe.

Safe mode with recovery mode

When the computer makes three unsuccessful attempts to start, it will automatically enter Safe Mode through the Windows recovery process. You can force this mode by pressing the reset button on your PC in three consecutive boot attempts. Once you enter recovery mode, choose “Troubleshoot”, then “Advanced Options” and finally “Startup Repair”.

On many occasions, this system will detect problems and fix them automatically. If not, you can also select “Startup Settings” and from there launch Safe Mode.

Safe mode with an installation disc

If you have a Windows 10 installation disc (or USB pen drive), you can also access recovery mode by starting the PC from the device. It will give you the option to reinstall Windows, but you can also go to advanced options, accessing the same recovery menu that we have seen before. From here you also have the option to select the “Recovery Manager”, which will also detect problems and try to solve them.

Disable Fast Boot in BIOS

There is an option within the BIOS or UEFI on most modern PCs called Fast Boot that allows Windows (since version 8, not just Windows 10 anymore) to start more quickly by preloading the drivers. Unfortunately, Windows updates can cause this option to cause problems loading outdated drivers. So, if your Windows PC won’t boot especially after installing operating system updates, it’s worth going into BIOS and disabling this setting, as it will often fix the problem. If after doing so the system already boots, you can go back to the BIOS and activate it because it will have already loaded the updated drivers.

Disconnect all USB devices

Returning to the issue of drivers, although it seems absurd sometimes Windows does not start because it is detecting a USB device from which it is not capable of loading the drivers, so it is worth trying to disconnect all the USB peripherals that you have connected (including keyboard and mouse ) and try to turn on the PC like this.

Reassign drive letters

Sometimes, and again especially after installing Windows updates, Windows 10 itself may not start, the problem is that the disk drive assignments have been deconfigured. This normally only happens when you have multiple hard drives installed on the PC, so if this is not the case you can skip this part.

To fix it, you will have to access the recovery mode as indicated above, but you will have to select the option to access the command prompt or command prompt. Once the window is open, you must run diskpart by simply typing it.

Once this is done, run the ” list volume”  command to see what drives you have on your system and what letters they are assigned to.

If you see that there is something that is not correct, from here you can select it with “select volume X” where X is the volume number, and “assign letter X” to assign the corresponding drive letter, where X is logically the lyrics.

Avoid the new Windows 10 Boot loader

If none of the above has worked, it is possible that an update has installed the new Windows 10 Bootloader, which sometimes causes problems again when there are several disk drives in the PC. Fortunately, it is easy to use the previous version again, and for this you have to go back to the command console loaded through recovery mode and enter the following command:

bcdedit / set {default} bootmenupolicy legacy

Restart the PC and you will see that the Windows 10 start interface has changed to a much more “archaic” one, but that gives less compatibility problems.

Repair or reinstall Windows 10 boot problem

If none of the above has helped and Windows still won’t boot, then you may need to reinstall or repair the operating system. To do this, you will have to access recovery mode again and, in this case, select the corresponding option. You can restore the system, go back to the previous version or reinstall the system. We can do little more if Windows 10 does not start, since the restoration options are minimal beyond having a full disk backup. Also, download windows 12 iso.
