About Partition Magic
Partition Magic (originally developed by PowerQuest) is one of the most popular partition management tools. It allows users to create, delete, format, and resize partitions on a hard disk drive.
After PowerQuest was acquired by Symantec, Partition Magic continued to be available for a time. However, as of December 8, 2009, Symantec officially announced that it would no longer offer PartitionMagic.
The latest stable version, 8.05, only supports pre-Vista Microsoft Windows operating systems, including Windows 2000 and Windows XP. It is incompatible with Windows Vista and later versions (Windows 7, 8, 10, 11), as well as 64-bit Windows systems.
Because Partition Magic cannot run on modern Windows versions, you may need a Partition Magic alternative to manage hard disk drives on Windows 11 or Windows 10 effectively.
When You Need A Partition Management Tool?
Even if you’re not a computer expert, you’ll likely encounter situations that need to adjust the partition size. Here are the most common ones:
|
Scenario |
What You See / Need |
Can Windows Disk Management do it? |
|
New hard drive / New PC |
Your new hard drive has only one partition or unallocated space, but you need to create more partitions to organize files. |
Yes (Create simple volume) |
|
C: drive is running out of space |
The C: drive is constantly red, system slows down. You want to allocate free space from the D: drive to extend C:. |
No (Cannot directly merge D: space into C:) |
|
Move partition |
Reposition a partition (e.g., D:) that is blocking you from merging C: and unallocated space. |
No (Cannot move partition) |
|
Not enough space for games or apps |
You want to install a large game (like Fortnite) or the Adobe suite, but the target partition is full. |
Yes, but troublesome (Requires deleting or moving files manually) |
|
Wrong partition format |
You want to convert a USB drive or external HDD from FAT32 to NTFS to copy files larger than 4GB. |
Yes, but destructive (Requires formatting, which erases all data) |
Besides the scenarios we mentioned above, many users may encounter more problems that Windows built-in tool cannot solve it:
- Merge unallocated space to C: drive flexible: Your C drive is out of space, but the unallocated space is non-adjacent to the C: drive.
- Migrate OS to SSD: You want to transfer the entire Windows system from a slow old HDD to a new faster SSD without reinstalling.
- Convert disk from MBR to GPT without data loss: You need to change your disk from MBR to GPT to meet Windows 11’s requirements, keeping all files intact.
- Create a bootable USB: Build a recovery USB drive in advance so you can repair boot issues even when your PC can't start normally.
You can determine whether you need a professional partition management tool based on the scenarios above.

It also has various other features, including being able to convert between FAT16, FAT32, and NTFS, modify the cluster size of FAT16, FAT32, and NTFS filesystems, and merge adjacent FAT or NTFS filesystems (all without data loss, though some NTFS-only metadata is lost on conversion to FAT).

Before resizing the system partition, it is recommended that you back up your system using AOMEI Backupper in case of unexpected issues.
Here are step-by-step guides on how to solve the most typical operation scenarios on Windows 11 with this powerful free partition software.
Scenario 1: New Hard Drive or New PC
You just bought a new hard drive that shows as unallocated space in Windows Disk Management, or a new Windows 11 PC that only has one C: drive. You want to create one or more partitions to store files.
It is a piece of cake for AOMEI Partition Assistant, which can help you to create partition on Windows 10 or 11 safely.
Step 1. Install AOMEI Partition Assistant Standard and launch it. The basic situation of your hard drive will be displayed in the main interface.
Step 2. Creating partition with AOMEI Partition Assistant Standard is an easy operation. You can create a partition from the C: drive directly. Right-click the C: drive, select Create Partition in the menu.
If the new hard drive is displayed as unallocated space, you can use the same method to create one or more partitions according to your needs.
Step 3.Here you can adjust the partition size according to your needs. After that, click OK.
Step 4. Confirm the operation, and click Apply to execute the task.
Scenario 2. C: Drive Is Full
With data increasing day by day, the C: drive has become full. Your PC will warn you “Low Disk Space”. You may face these situations:
C: drive is full, and there is unallocated space next to it
In this situation, you can fix it with Windows Disk Management. There is no need for partition software.
Step 1. Open Windows Disk Management.
Step 2. Right-click the C: drive, select “Extend Volume”.
Step 3. Follow the Extend Volume Wizard to extend the C drive.
C: drive is red, but D: drive has lots of free space
In this case, Windows Disk Management cannot do anything. You may want to take free space from D: drive and add it to C: drive without losing data. Fortuantely, AOMEI Partition Assistant allows you to add disk space from D: drive to C: drive with only 3 steps.
Step 1. Launch AOMEI Partition Assistant.
Step 2. Right-click D: drive >Move/Resize Partition. Drag the left border of the partition to the right to create unallocated space. Click OK.
Step 3. Then, drag the left border to the right to free up some unallocated space neighbouring your C: drive, and click OK.
Step 4. Right-click C: drive > Move/Resize Partition. Drag the right border into the unallocated space (released from D: drive) to extend C: drive. Click OK.
Step 5. Click Apply->Proceed to extend C: drive with free space from D: drive.
C: drive is full, but the unallocated space is not adjacent to C:
Windows users may find that if the unallocated space is not adjacent to C: drive, you can't use Windows Disk Management to extend C: drive, because the button "Extend Volume" greyed out.
But With AOMEI Partition Assistant, you can merge unallocated space to C: drive easily and safely, even if it is not adjacent to C: drive.
Step 1. Launch the program. You can see the C: drive is almost full, and the unallocated space is not adjacent to C: drive. Don’t worry. It’s easy. Right-click C: drive, Advanced -> Merge Partitions.
Step 2. Check the box in front of C: drive and the non-adjacent unallocated space. Click OK.
Step 3. Click Apply and wait a minute until it’s finished.
Scenario 3. Dual Booting
You may need to run two operating systems on one PC. For example, you want to dual-boot Windows 10 and Windows 11 on one PC, but you only have one C: drive. Then, you need to shrink the current C: drive to create space for a new OS partition. Windows Disk Management can shrink partitions, but AOMEI Partition Assistant is more flexible.
Step 1. Launch AOMEI Partition Assistant. Right-click the C: drive and select Move/Resize Partition.
Step 2. In this window, drag the right partition bar to the left to create space for installing a second OS.
Step 3. Confirm the partition size and click OK->Apply.
Then, you will get another partition for dual-boot.
Scenario 4. Installing A New OS
You want to install Windows 11, but your disk is MBR. So, you need to convert MBR to GPT before installing Windows 11. AOMEI Partition Assistant can help you convert MBR to GPT disk without data loss (Supported by its Professional edition).
Step 1. Launch the application. Right-click the MBR disk and select “Convert to GPT”.
Step 2. Confirm the conversion and click OK-> Apply.

Frequently Asked Questions (FAQ)
Q: Is Partition Magic still available for Windows 11/10 64-bit?
A: No. The original Partition Magic (last version 8.05) was discontinued by Symantec and does not officially support any 64-bit Windows system, including Windows 11, 10, 8, or 7. Using it on these systems can cause crashes or boot failures. This is why a reliable Partition Magic alternative is necessary.
Q: Will using AOMEI Partition Assistant cause data loss when I resize a partition?
A: When using a trusted tool like AOMEI Partition Assistant, the risk of data loss is very low for standard operations (resize, move, merge, create, delete). The software uses a transaction-based technology. However, as a best practice, it is strongly recommended to back up critical data before making any changes to your disk partitions. For a free backup solution, you can use AOMEI Backupper Standard.
Q: What are the main differences between the Free (Standard) and Professional editions?
A: The Free version handles basic partition management (resize, move, merge, create, format, delete) perfectly. The Professional edition adds advanced features for power users, including:
- Allocate Free Space: Move free space from one partition to another directly.
- Convert MBR to GPT without data loss: Essential for upgrading to Windows 11 or enabling UEFI boot.
- App Mover: Move installed programs to a different drive or partition.
- Partition Recovery: Recover lost or deleted partitions.
Q: Can I use AOMEI Partition Assistant on Windows Server?
A: Yes. While the Standard and Professional editions are for Windows 11/10/8/7 (both 32-bit and 64-bit), AOMEI offers a separate product called AOMEI Partition Assistant Server specifically designed for Windows Server 2008, 2012, 2016, 2019, 2022, and 2025.
Final Words
Since Partition Magic hasn’t been updated for years and does not support 64-bit versions of Windows 11, 10, a free Partition Magic alternative is necessary. AOMEI Partition Assistant should be the best Partition Magic alternative for Windows 11/10 (64-bit) partition management.
