This PC Can’t Run Windows 11 - Fix

Seeing the error “This PC can’t run Windows 11” can be frustrating, especially if your computer seems powerful enough.

This message usually appears when your device doesn’t meet one or more of Microsoft’s system requirements like TPM 2.0, Secure Boot, or CPU support.

In this guide, you’ll learn how to fix the “This PC can’t run Windows 11” error and successfully install Windows 11.

Why You See “This PC Can’t Run Windows 11”

The error appears when your PC fails one of these requirements:

TPM 2.0 not enabled
Secure Boot disabled
Unsupported CPU
Not enough RAM or storage
Legacy BIOS instead of UEFI

Fix 1: Enable TPM 2.0

TPM is one of the most common reasons for this error.

Steps

Enter BIOS (see How to Enter BIOS in Windows 11)
Go to Security or Advanced tab
Enable:
- Intel PTT (Intel systems)
- fTPM (AMD systems)
Save and restart

Fix 2: Enable Secure Boot

Secure Boot must be enabled for Windows 11.

Steps

Open BIOS
Go to Boot tab
Set Boot Mode = UEFI
Enable Secure Boot
Save changes

Fix 3: Check System Requirements

Make sure your PC meets minimum specs:

4GB RAM (8GB recommended)
64GB storage
Supported CPU
UEFI firmware

You can check this by pressing: Windows + R → type: msinfo32

Fix 4: Convert MBR to GPT (If Needed)

Windows 11 requires UEFI + GPT partition style.

Steps

Open Command Prompt as admin
Run: mbr2gpt /convert /allowfullos
Restart and enable UEFI in BIOS

Fix 5: Use Rufus to Bypass Requirements

If your PC truly doesn’t meet requirements, you can bypass them using Rufus.

Steps

Open Rufus
Select Windows 11 ISO
Enable:
- Remove TPM requirement
- Remove Secure Boot requirement
Create bootable USB
Install Windows

Fix 6: Update BIOS

Sometimes TPM or Secure Boot options are missing because BIOS is outdated.

Steps

Visit your motherboard manufacturer website
Download the latest BIOS version
Update BIOS carefully

Should You Upgrade or Stay on Windows 10?

If your PC doesn’t fully support Windows 11:

Upgrade if:

You want the latest features
Your hardware is relatively modern

Stay on Windows 10 if:

Your PC is older
You prefer stability
You don’t want to bypass requirements

The “This PC can’t run Windows 11” error is usually caused by missing TPM, disabled Secure Boot, or incompatible system settings. In most cases, enabling these features in BIOS will fix the issue.

If your hardware is unsupported, you can still install Windows 11 using bypass methods like Rufus.

After installation, don’t forget to activate your system using a genuine Windows 11 Pro product key from our store.
