[Fixed] Your PC Can’t Run Windows 11

After being updated several times, Windows 11 has fixed many issues and become more and more acceptable among many Windows users. Some of them decide to upgrade from Windows 10 to Windows 11 at this time point. Users who have some PC knowledge or are familiar with tech may finish this job quickly, however, it may not easy for normal users.

Why your pc can't run Windows 11?

In most circumstances, being unable to run Windows 11 is due to a failure to fulfill the Windows 11 operating system's basic requirements.

The bulk of Windows 11's minimal system requirements is similar to those of Windows 10. In truth, the GPU, CPU, and RAM requirements are at the ordinary level, and most PCs will match Microsoft's minimal threshold.

Apart from the hardware, there are only 4 problems that may impede you to run Windows 11 on your computer:

• Storage capacity of the system drive
• UEFI mode
• Secure Boot
• TPM 2.0

If you see the message “This PC can’t run Windows 11”, and the reasons are related to these four factors, in this post, we’ll tell you how to fix this issue with some useful solutions.

How to fix [Your PC can’t run Windows 11]?

Case 1. Extend insufficient system disk space

If the warning you received is “The system disk needs to be 64 GB or larger…”, then you need to extend your C drive space. Disk Management can extend volume if there’s adjacent unallocated space on the right of your C drive, or you can delete the drive next to your C drive and use it to extend your system drive.

But, not all users can accept to delete data and not all unallocated space stays at the right location. To easily extend the C drive, here we recommend you AOMEI Partition Assistant Professional, which is a disk manager for Windows 11/10/8/8.1/7/XP users. The “Merge Partition” feature can merge non-adjacent unallocated space to the C drive. The “Allocate Free Space” function allows users to directly add free space from one drive to another drive without data damage.

Step 1. Launch AOMEI Partition Assistant, right-click the partition from which you want to allocate free space, and select "Allocate Free Space". 

Step 2. You will get a pop-up window. Type in the size of the free space which you want to cut from the D partition and this free space will be directly added to the destination partition.

Step 3. Click "Apply" to execute this operation.

Then you need to reboot your computer to finish the operation since it’s a system drive, after that, you can see that your C drive has more space.

Case 2. Change to UEFI mode and enable Secure Boot

Because UEFI (Unified Extensible Firmware Interface) is a characteristic of your motherboard, there is no way to add UEFI support if your device does not support it. It’s a boot mode like Legacy. But the difference is that the UEFI needs a GPT partition scheme disk as the boot disk while the Legacy mode requires an MBR disk.

In Windows 11 requirements, UEFI and Secure boot are essential lines, since Secure boot only serves in UEFI mode, which means to satisfy these two points, you’ll need to convert your system disk to a GPT partition scheme if you’re using an MBR disk as a system disk.

Section 1. Change to UEFI mode

Diskpart and Disk Management both allow users to convert the disk unless they can accept to clean all data on the disk. There’s an MBR2GPT tool for Windows 10 users, but it doesn’t support Windows 7/8/8.1.

AOMEI Partition Assistant can also help you if you can’t use MBR2GPT. It can convert system disk and data disk between MBR and GPT without data-deleting requirement. And with only a few clicks, you can finish this job.

Step 1. Launch AOMEI Partition Assistant. Right-click the system disk and choose “Convert to GPT”.

Step 2. Click “OK” to confirm your operation.

Step 3. Click on “Apply” to commit the pending operation.

After you’ve changed your disk to a GPT partition scheme, let’s move to the next part to enable Secure Boot.

Section 2. Enable Secure Boot

Start your computer and press the functional key (generally, it is F1, F2, F3, F10, or F12, ESC) to enter the firmware interface when you see the first screen. The functional key is different from computer to computer. Under the BOOT tab, choose the UEFI/BIOS Boot Mode, and change the Legacy to UEFI. Then save and exit the firmware interface.

Step 1. Reboot your computer and hit ESC/Delete/F1/F2/F10 to enter the BIOS system (the keys are different depending on computer hosts). Then, click on “Boot” and select “Secure Boot”.

Step 2. Now, you can secure boot is shut down. Click on the “Key Management”. Then, select “Install default Secure Boot Keys” to enable secure boot.

Now you’ve enabled Secure Boot.

Case 3. Enable TPM2.0

TPM stands for Trust Platform Module. It is a separate chip that performs encryption, decryption, privacy protection, and other purposes. This chip functions as hardware safe, locking vital data such as the user's key, credentials, and biometric traits. Most modern devices have TPM2.0, you can check it whether is enabled or not.

Step 1. Press “Win” and “R” together, then type “tpm.msc” and click “OK”.

Step 2. Open the TPM management window, if the “Status” lab shows “The TPM is ready for use”, it means that the TPM is already enabled. You can check the TPM version in the right corner.

If the TPM version is compatible but disabled. The screen will show “Compatible TPM can’t be found”. In this situation, you need to turn it on in the BIOS.

Step 1. Press “Shift” to enter the Windows Advanced Options menu after you click restart, and go to Troubleshoot > Advanced options> UEFI Firmware Settings.

Because the computer's motherboard is different, the name in the BIOS setting will be different. TPM and PTT serve the same purpose; simply open it. On certain PCs, the TPM will be located under the advanced settings and will be known as the Trusted Platform Module.

Case 4. Run Windows 11 on unsupported PC

Some users might need to run Windows 11 for testing programs or other purposes. If you just need a Windows 11 environment but your device can’t run Windows 11, you can use AOMEI Partition Assistant to make a Win 11 to Go USB or disk to run this OS on your PC.

Step 1. Launch AOMEI Partition Assistant Professional, click “Tools” and “Windows To Go Creator” on the top menu.

Step 2. Select “Create Windows To Go” for your personal computer and click “Next”.

Step 3. Choose the suitable option "Create Windows To Go with system disc/ISO". If Windows 11 ISO file isn’t detected automatically, click the folder icon to select it manually. Then, click “Next”.

Step 4. Select the removable device and click “Proceed”.

Step 5. You’ll receive the message that all data on this USB drive will be erased. Click “Yes” to continue.

After that, you can boot your computer from this Windows 11 To Go device. Don’t forget to change the boot device in the BIOS.

Wrap things up

If your PC can't run Windows 11 and you’re sure your hardware meets requirements, then hopefully this article can help you fix the problems.
