In case you are getting an error code 0x8007007f while downloading the Windows 11 ISO file, read this guide on how to solve this issue. Let’s learn what extra can you do to ensure Windows 11 installation doesn’t fail mid-way on your PC. 

Fix - Windows 11 won't install

Note: Windows 11 won’t install error comes only when your PC doesn’t meet the minimum system requirements. Work on them and this error will fade automatically.

Fix – Windows 11 won’t install

If you are not able to install Windows 11 on your computer, this must be because of the following reasons. Worry not, as we have brought a fix to each one of the below underlying causes. All you need is to read the below segments and find out which one exactly is the issue in your case. 

1. Compatibility Check

With each version new version of Windows, Microsoft releases a new set of hardware that is compatible with the new operating system.

If you haven’t yet come across this or have knowingly left out this, we suggest having a look at the compatibility list and seeing if your device meets the minimum system requirements.

  • RAM & ROM: 4 GB and 64 GB.
  • Processor: Must be a dual-core with a clock speed of at least 1 GHz or higher. In the case of AMD processors, it should be on at least Ryzen 2000 series or newer. 
  • System Architecture: With Windows 11, Microsoft stops supporting 32-bit based PCs. So, your device must be on either x64 or ARM64.
  • Your PC must support TPM 2.0: This is of absolute importance. See how you can check the current TPM module on your computer.
  • Resolution & color: A minimum of 720 pixels with 8-bit color.
  • Your PC must support a secure boot-capable UEFI.

Note: Though this doesn’t come under minimum system requirements, it is important to ensure whether you are on an active internet connection or not. This is important as Windows 11 requires downloading an ISO image file that is roughly around 5+ GB in size. 

Only when your device meets all of the above requirements, proceed ahead to know the reasons why Windows 11 is not installing on your computer. 

How can I check minimum system requirements automatically?

It is quite easy to see what your device is capable of by getting into the System Information window. Press Win + S, type “System information”, and double-click on the top result. In the subsequent window, you may see all information under System Summary.

If for any reason you don’t want to get into checking this manually, download and install the app – “PC Health Check“. After you install this software successfully, double-click on it to see if your device is compatible or not. 

WhyNotWin11 is another important tool that you may use to find the reasons that are preventing you from installing Windows 11 on your computer.

2. Check and Enable TPM 2.0

For Windows 11 to install successfully, your device must support TPM module 2.0. Here’s a complete guide on how to check and enable the Trusted Platform Module on any PC. 

Though there are ways using which you can bypass this minimum TPM requirement, Microsoft is totally against doing so. They even warn their users against such installation as this will break the core functions of this operating system. If you don’t want to get into any issues after installing Windows 11, we also suggest ignoring such a bypass. 

3. Check and Enable Secure boot

Secure Boot has become an important aspect these days with the buzz of Windows 11. Though it was always there, many users kept it disabled. They do so only to run certain versions of Linux or older versions of Windows. As you are trying to install Windows 11 which is completely a new operating system, go and check the current status of Secure Boot on your PC. 

Tip: A disabled secure boot PC is more vulnerable to malware and viruses. So, turn it back ON even if you are not able to install Windows 11. 

4] Boot Windows 11 using an ISO image

In case your device supports both TPM 2.0 and Secure boot, yet Windows 11 won’t install, you should get the ISO image file. Once you have the ISO image of Windows 11, make it bootable using Rufus. Make sure to select UEFI (non-CSM) instead of MBR under the section – Target system

After you have created a bootable image of Windows 11, read this guide on how to fresh install Windows 11 into your PC.

What to do when Windows 11 is not running properly?

If you have already installed Windows 11 on your computer and are getting into issues, you may try to reinstall Windows 11 again. In case the issue persists even after this, go back to Windows 10 version 21H1.

How do I install Windows 11 on my PC?

If your PC supports all of the above-mentioned prerequisites, navigate to the path below, and hit Check for updates.

Settings (Win + I) > Update & Security > Windows update

The system will run a compatibility check on your device. When it finds your PC fully compatible, you’ll see a Feature update to Windows 11. Click Download and install, and wait for this to complete. While upgrading to Windows 11 this way, make sure to remain on a high-speed internet connection. Else, the download will fail mid-way wasting all your data pack and time as well.
