9 solutions to try when PC is not booting

We all get frustrated when our PC is not booting. And while sometimes there is a clear error message that can be saved quickly, there are other times when you don't get any indication of what the reason might be.

This type of problems have been there for years with all versions of Windows and they are still here with Windows 10. In this article, we gathered some of the most common reasons of why PCs may not be booting up with solutions.

Solutions if your PC is not booting

Try 'safe mode' 

One of the easiest solutions that sometimes work when the PC is not booting is starting the computer in safe mode. Safe mode runs a basic copy of windows without your installed apps.

This way, it can bypass any problems with software or with the drivers. So, simply running the PC in safe mode solves the problem and enables it to start normally.

If you can't reach Windows recovery to run safe mode, you can use the installation drive to run it. 

Check the battery 

If you are using a laptop, the battery can be the reason why your PC is not booting. Testing another charger can be a quick check, then after confirming that the charger is working you can remove the battery to check if it is the problem. 

While doing this you need to ensure you are organized and checking one thing at a time to avoid being distracted. If you find that the battery is fine and the charger is good you can start trying other solutions. 

Unplug all USB devices 

unplug all your USB devices

Windows 10 is always updating and some updates cause a conflict with a USB device. This can cause your PC to not boot. If that is the problem, the solution is easy to try.

Unplug all USB devices from your PC if it doesn't boot. Then try to start it. Sometimes you don't even need to restart the PC. Only removing the USB device causing the conflict can solve the problem and the PC turns on. 

Turn off Fast Boot 

Fast Boot is a feature in BIOS or UEFI that works with Windows 8 and later versions. It is intended to make booting faster by preloading drivers.

Windows updates can mess up with the feature and cause your PC to be unable to boot, but fortunately you can easily turn off the feature from your BIOS. 

There is no single way to enter your BIOS or UEFI, but it is generally one keyboard shortcut you need to press quickly when the PC runs.

This shortcut is usually Delete, F2 or Escape key. If the key to press is not being shown on the screen, googling or returning to the motherboard manual can also help. 

Try PC malware scan

Malware is one of the most common reasons computers don't boot. Usually the method to deal with it is an anti-malware software that can be booted from a USB or DVD drive.

There are a number of free tools you can use that are bootable from USB and DVD drives. These include AVG Rescue CD and Bitdefender Rescue Disk.

All you need to do is burn the tool on a DVD or USB drive then boot it from there. Then follow the steps to let it try to eliminate malware from your computer that may be causing it to not boot.

Use system restore 

There are a few good utilities you can try to solve the problem which are available with Windows installation disk. To run one of these utilities, you need to get Windows installation disk or burn it again on a DVD or USB drive then boot from it. 

Once the disk is booted, you will see a number of choices instead of installing a new copy of Windows. One of them is Advanced Options. From there, find Startup Repair which you can try first to give Windows a chance to solve the problem. 

If the Startup Repair tool doesn't work, then you may have to do a System Restore. This utility restores your PC to the point when it was working normally. This can solve booting problems caused by software updates or conflict.

Reassign drive letters

When your PC is not booting, one of the common reasons for that is the conflict in assigning drive letters. If you have unintentionally assigned a drive letter then it can be causing all this mess, but the solution is still easy. 

All you need to do is to load the command prompt, which you can load using the Windows installation disk. Following this, type 'diskpart' and press Enter to load the disk part tool that allows you to make all types of changes to your disk and its volumes.

Type 'volume list' and press Enter to load the volumes you have. Select the volume using its number using 'select volume 0' for example and press Enter. Then type 'assign letter=E', or any other letter and press Enter.  

Try a Boot Repair Disk 

One of the solutions you should give a try if your computer persists and doesn't want to boot is the Boot Repair Disk. This third party tool is made to diagnose the issue with computers boot and solve them. 

The open source tool is easy to use. All you have to do is select if your Windows is 64 or 32 bit, everything else works automatically. There are also manual options you can use if you want. 

Try Factory Reset

Try Windows Factory Reset

If you tried all solutions you can but still the PC is not booting, you have another final choice to fix your computer yourself by doing a Factory Reset.

Referred to as Reset in the Windows installation disk options, the utility will delete your apps and user data. This sounds excessive but it can be the solution you need. 

Fortunately, you can choose to keep your files while resetting your copy of Windows. This will return Windows to its original copy but still keeps your important files.
