▶ Part 2. How to meet Windows 11 requirements with AOMEI Partition Assistant?

Since AOMEI Windows 11 Update Checker will give you detailed fixes once your computer doesn't support upgrading to Windows 11, like enabling TPM 2.0 or Secure Boot, this part will mainly talk about how to enlarge storage space and convert disk partition type into GPT with AOMEI Partition Assistant.

✎ Extend C drive

If your disk storage doesn't meet the 64GB or larger requirements, Windows system won't allow you to upgrade to Windows 11 directly. Thus, you need to extend your system drive in the first space. When you plan to extend C drive via Disk Management or DiskPart, please make sure there is adjacent unallocated space on the right of your C drive.

Apparently, not all users can ensure there must be unallocated space on their disks. Thus, to enlarge C drive easily and safely, AOMEI Partition Assistant Professional should be your top priority. This versatile disk manager will provide you with different methods to meet your different situations. For instance, the "Merge Partition" function can merge non-adjacent unallocated space to the C drive, and the "Allocate Free Space" feature enables you to directly move free space from one partition to C drive without data loss.

Step 1. Install and open the AOMEI Partition Assistant Professional, and right-click the partition that has enough space, and choose "Allocate Free Space".


Step 2. Here you can set the allocated size as you wish to C drive, and click "OK".


Step 3. Click the "Apply" in the main interface to start allocating free space to C drive.


✎ Convert MBR to GPT

Because UEFI (Unified Extensible Firmware Interface) is the essential condition for Windows 11 upgrade, you must make sure your motherboard can support it. Since the UEFI is for GPT partition scheme while MBR is for BIOS, it means you need to convert your system disk to GPT if you are running on an MBR system disk.

Although Diskpart and Disk Management both allow you to convert the disk from MBR to GPT, you must delete all the partitions on it to make sure your system disk is totally empty. This is because these two Windows built-in tools only convert empty disks. Sounds terrible? Don't worry, AOMEI Partition Assistant is also an MBR2GPT tool for Windows users. Only in a few clicks, it can convert the system disk or data disk between MBR and GPT partition style without deleting any partition or reinstalling OS.

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 converting MBR to GPT successfully, don't forget to change BIOS to UEFI to ensure the Windows 11 can run normally and smoothly.



That's all about Windows 11 PC health checker and how to use it. If you really want to upgrade to the newest Windows 11, I highly recommend you to try AOMEI Partition Assistant. It's such a powerful disk manager that it can not only check your Windows 11 compatibility but also helps you update the incompatible configuration. Besides, if you want to protect your data or improve performance, you could clone your disk to another HDD/SSD or migrate OS to SSD. If you are a Windows Server user, the Server edition is waiting for you.
