How to Install Windows 11 on a Dell laptop

Thinking of upgrading to Windows 11? Here's a short guide on how to do exactly that, whether you want to use Windows update or perform a clean install. This guide is specific to Dell laptops. Alternatively, we have a video version of the guide.

For all Windows 11 editions, internet access is required to perform updates and to download and take advantage of some features. A Microsoft account is required for some features.

Whilst there may be unofficial ways to install Windows 11 on older hardware, this guide is not focused on that.

Option 1: Installing with Windows update

You have two options when updating to Windows 11, this option involves using Windows Update. It's the easier of the two and you don't have to do much. All of your data should be safe this way but just in case we reccommend you perform a backup of your data.

If your system is compatible, it may be possible to upgrade from Windows 10 to Windows 11 through Windows Updates. Simply access the Windows Update section of the settings menu, and look for an option to upgrade to Windows 11.

If the option does not appear, download and install the PC Health Check app from Microsoft’s website.

Run the app and select “Check now “ under the Windows 11 section. The app should tell you whether or not your system can run Windows 11. If there are compatibility issues, you will not be able to install Windows 11 officially until any issues have been resolved. If you are running Windows 10, don’t worry as it will still receive support until October 2025.

Once you have Windows 11 installed, you will have 10 days to revert back to Windows 10 if you change your mind. All new data form after the installation should carry backwards if you choose to downgrade. If you decide to downgrade after the 10 days you will need to complete a clean install of Windows 10.

Option 2: Clean install

Option 2 is a clean install of Windows 11. Any data on the system and on the installation media tool you will create during this process, will be deleted. We recommend you create a backup of all your data to a seperate device. 

Part 1: Prepare what you'll need

You will need a Dell laptop, a compatible charger and a USB that is at least 8GB.

Use Microsoft's free Windows 11 Installation Media tool, to create a Windows 11 boot USB. Run the tool and follow the on screen instructions.

Once the USB has been created using the tool, make a new folder (Call it “Dell Drivers” to be simple, you can use other names, as long as it does not clash with any folder name that's already there); this folder is intended to hold the optional drivers for you to install later.

Optional: Downloading Drivers

After Windows 11 has installed you will need to update your device's drivers using Windows Update & Dell Support Assist. Sometimes some drivers may get lost during the update process such as the wifi driver so you might not be able to connect to the internet afterwards. Before you update it's best to download those drivers just in case, especially if you don't have another device that you can use afterwards to troubleshoot.

Use the Dell website, you can access this through Dell Support Assist, to download the wifi drivers specific to your device. Once downloaded, move them to the 'Dell Drivers' folder on your USB that you made during the previous step.

Skip this step if your laptop does not have a dedicated graphics card. Download the graphics driver into the folder where applicable. For NVIDIA graphics cards, goto NVIDIA's website & download the graphics driver.

Part 2: Backup your data

As we are performing a clean install of Windows 11, the drive Windows is installed on will be wiped of any data, so make sure to backup any data you wish to keep on either a removable drive or in cloud storage.

Part 4:

While previous versions of Windows could run in Legacy, Windows 11 requires your system to be running in UEFI to be compatible. More modern machines may not support Legacy mode and only UEFI anyway. 

Turn on your laptop and repeatedly press F2 to enter the BIOS.

1: General > Advanced Boot Options > Disable Legacy Option ROMs

2: Security > TPM 2.0 Security > Enabled and TPM On

3: Security > Secure Boot > Secure Boot Enable

4: Exit > “Exit Saving Changes”

Part 5: Install Windows

-Insert the Windows 11 USB you’ve made into your laptop

-Shutdown your PC, and while restarting it, press Esc or F12 until you enter the Startup Menu. Select your Windows 11 USB from this menu

-Follow the on screen instructions to install Windows 11 (Make sure to delete the files on the drive containing the previous Windows installation)

Part 6: After Windows has been installed

Once you're in Windows:

Step A: Install the graphics drivers first. Initially, the system will appear to be less responsive / the internet appears slow.

This is because it is updating the drivers in the background. An idea is to leave the laptop for 10-15mins whilst it sets up (depending on your internet speed this could take longer). Install the wifi driver if you can't connect to the internet and you cant see the driver in device manager.

Step B: Open "Windows update", select update if it doesn’t automatically do so, and let it find more drivers (restart once it requests).

Step C: Install HP Support Assistant and use it to install the remaining updates automatically. If it gets stuck during its opening, just restart the system and try loading this app again.

Step D: Open Windows’ Device Manager (either by searching for Device Manager in the search bar, or by holding the Windows Key and pressing X and choosing Device manager) and check if there are any devices missing under “Other Devices”.

If any devices still do not have drivers, search for the drivers manually on the Dell website.
