Guide 2. Run Windows 11 Checker on a Windows 8 PC to Test If It Supports Windows 11

There are many Windows 11 compatibility checking apps available online, and you can download one for help. Although Microsoft is said to produce its own Windows 11 checker, named a PC health check, it is not available yet.

Here, we'll show you how to check the compatibility of your computer for Windows 11 with EaseUS Windows 11 Upgrade Checker.

Step 1. Launch EaseUS Partition Master and click "Toolkit".

Step 2. Click "Win11 Checker" to open this feature. Then click the Check Now button to start.

Step 3. The Windows 11 compatibility result window will soon appear. All the incompatible and compatible configuration items will be listed.

Note that all you need is to focus on the incompatible configuration section. If you see any one of the issues show up in the result, it means that your computer currently doesn't support Windows 11:

• Disk Partition Type
• Boot Method
• Secure Boot
• TPM

So, can I fix these issues and make Windows 8/8.1 ready for the Windows 11 upgrade? Sure. In the next part, you'll learn how to get rid of these 4 major issues that block your computer from Windows 11.

Guide 3. Fix Windows 11 Compatibility Issues in Windows 8.1/8 PC

This part contains 3 fixes for you to follow and respectively get rid of the above issues and make Windows 8 computers support Windows 11. Let's see the details.

#1. Convert OS Disk from MBR to GPT

Windows 11 requests the OS drive to be GPT for UEFI and Secure Boot Modes. So you can open Disk Management and right-click OS disk to check its disk type now. If it's MBR, you'll need to convert it into GPT for a Windows 11 upgrade. 

Here, you can turn to reliable partition manager software - EaseUS Partition Master for help. It converts your disk to MBR or GPT type without losing any data. 

Here is how to do so:

Besides, you can also try Disk Management or CMD to delete all partitions for disk conversion to GPT. However, this is not a user-friendly solution as both methods require data and partition deletion. For a safe disk conversation between MBR and GPT, you can fully trust EaseUS Partition Master with the above guide.

Note that to make your computer boot up from GPT and get ready for Windows 11, you'll need to fix the Boot Method and Secure Boot Issues next. And don't hesitate to share this article to let more users know about them.

Step 1. Restart the PC and press F2/F10/F12/Del to enter BIOS.

Step 2. Go to the Boot Menu, click the Boot Mode section, and see if your computer supports UEFI mode.

To get a Windows 11 update, you'll also need to ensure that your computer supports TPM 2.0 and enable it.

Guide to Check If Your Windows 8 PC Supports TPM 2.0:

Step 1. Press the Windows + R keys, type tpm.msc in the Run dialog, and click "OK".
