Upgrading to Windows 10 or installing it is although a simple process but sometimes there can be some issue while or after installing or upgrading to it. A common issue we have witnessed recently is the boot error after installing or upgrading to Microsoft Windows 10 on the Dell computer systems. Hence, this blog is dedicated to troubleshooting the very boot error. Please note that it is always better to seek authorized help from the Dell chat support before troubleshooting the issue yourself.
So, precisely, your Dell system is powering on correctly and showing the Dell BIOS screen at the boot-up but it won’t boot to Microsoft Windows 10 successfully. A few symptoms you may be experiencing of your Dell laptop or PC are:
- The system proceeds past the Dell screen but Windows does not finish booting;
- The Caps Lock key is illuminated when toggled;
- The hard drive activity light may flicker, stay on or be off;
- An error message may be present;
- No diagnostic codes are present;
- The power button lights up solid under its usual operating colour; and/or
- No sounds are heard from the operating system
While it is always recommended to seek a Dell chat live session to resolve the issue quickly, below are a few methods you can try, too.
Fix 1. Check if the computer finishes the initial power-up (POST).
It is seen in many cases that a computer won’t hand over control to the operating system. The POST process is completed successfully when the bar on the Dell logo screen fills up completely and disappears. If this does not happen, it’s a call for a fix. Now, you need to hard reset your Dell PC.
To hard reset:
- Power off the PC.
- Disconnect the AC adapter or power cable.
- Remove the battery if you are using a Dell laptop.
- Disconnect all external USB and output devices from your computer system.
- Press and hold the power button for 15–20 seconds. This will drain any residual power from your laptop.
- Now, connect the AC adapter or power cable to your laptop and place the battery back to it.
- Power on the PC. This method should fix the booting issue. If the situation persists, you can always contact the Dell support to get personalized help, or just skip to the next method.
Fix 2. Reset the BIOS to factory settings.
- Restart your Dell laptop or PC.
- During the Dell logo on the screen, press the F2 key repeatedly until you see Entering Setup on the top right corner of the screen.
- Press a key listed at the bottom of the screen to load default settings. The key is specific to the BIOS your computer is using.
- Press ESC to exit the BIOS. Be sure to click on Save and Exit to save your changes.
There are a lot more methods to try out, but the most common and useful ones are the above two. However, we reiterate that you initiate a Dell chat live session so that the experts at Dell could see through your problem in a more specific fashion.
