Encountering the message "Windows 11 can't install on this PC" can be a frustrating experience, especially when you're eager to take advantage of the new features and improvements offered by Microsoft's latest operating system. This guide will help you understand these issues and provide solutions to ensure a successful upgrade.
Before troubleshooting, it’s crucial to understand the system requirements for Windows 11. Unlike its predecessors, Windows 11 has specific hardware requirements that must be met:
Processor: 1 GHz or faster with at least 2 cores on a compatible 64-bit processor.
RAM: 4 GB or more.
Storage: 64 GB or larger storage device.
System Firmware: UEFI, Secure Boot capable.
TPM: Trusted Platform Module (TPM) version 2.0.
Graphics Card: DirectX 12 compatible graphics / WDDM 2.x.
Display: >9” with HD Resolution (720p).
Processor: Intel Core i5 or AMD Ryzen 5 and above.
RAM: 8 GB or more.
Storage: 256 GB SSD or larger.
Graphics Card: Dedicated GPU for enhanced performance.
When trying to install Windows 11, you might encounter specific error messages. Here’s what they typically mean:
This message indicates that your hardware does not meet one or more of the basic requirements for Windows 11. Check the detailed requirements and compare them with your system’s specifications.
Windows 11 requires a compatible processor. This error suggests that your current processor does not meet the criteria set by Microsoft.
Secure Boot is a security standard designed to ensure that a PC boots using only software that is trusted by the manufacturer. If it’s not enabled, you might face installation issues.
Trusted Platform Module (TPM) 2.0 is essential for Windows 11. This message means that TPM 2.0 is either not present or not enabled on your PC.
Microsoft offers a PC Health Check Tool that can automatically assess whether your PC meets the requirements for Windows 11. Download and run this tool from the Microsoft website to get a detailed compatibility report.
If you prefer a manual approach, you can check the compatibility of individual components:
Processor: Check the list of supported processors on Microsoft's website.
RAM and Storage: Verify your system’s RAM and storage capacity in the System Information app.
TPM: Open TPM Management (tpm.msc) to see if TPM 2.0 is available.
Secure Boot: Access your BIOS/UEFI settings to ensure Secure Boot is enabled.
Ensure that your processor is on Microsoft’s list of supported CPUs. If not, you might need to upgrade your processor to a compatible one.
To enable Secure Boot:
1. Restart your PC and enter the BIOS/UEFI settings (usually by pressing a key like F2, F12, DEL, or ESC during startup).
2. Navigate to the Secure Boot section and enable it.
3. Save changes and exit BIOS.
To enable TPM 2.0:
1. Restart your PC and enter BIOS/UEFI settings.
2. Find the TPM section (may be listed under Security or Advanced settings).
3. Ensure TPM is enabled and set to version 2.0.
BIOS (Basic Input/Output System) is firmware that initializes hardware during the booting process before the operating system loads. Updating BIOS can resolve compatibility issues with new hardware.
1. Identify your motherboard model and visit the manufacturer’s website.
2. Download the latest BIOS update file.
3. Follow the manufacturer’s instructions to update your BIOS, which usually involves using a BIOS update utility provided by the motherboard maker.
Windows 11 requires at least 64 GB of storage. Ensure that your hard drive has enough free space for the installation process.
1. Use Disk Cleanup to remove unnecessary files.
2. Uninstall programs that you no longer use.
3. Move large files to an external drive or cloud storage.
