Unable to convert a partition to Ext4 from NTFS

My computer is running Windows 10 and with two hard drives. Now, I want to convert one NTFS partition to a Linux file system – Ext4. But when I open Disk Management to format it, I find that there is no Ext4 option offered. Then, I try to format the NTFS partition to Ext4 using Diskpart, but I only receive an error – Virtual Disk Service error: The file system is incompatible. Is there anyone can tell me how to convert NTFS to Ext4 in Windows 10 successfully?

File System Is Incompatible

Need third party partition manager software

Obviously, it is not allowed to format NTFS to Ext4 using Windows built-in tools like Disk Management. In such a condition, to complete conversion from NTFS to Ext4, third-party partition manager software will be helpful!

Among a great number of partition manager software, AOMEI Partition Assistant Standard will be my preference. This freeware is with an intuitive user interface, making it easy to handle.

Step 1. Install the freeware as prompts and run it. In the main interface, locate the NTFS partition that you want to convert to Ext4, and choose Format Partition.

Step 2. In the pop-up dialogue, choose Ext4 from various file systems. Here you can also add partition label and change cluster size of this partition if you want. Then, click OK icon.

Step 3. In the main interface, you can review operation. Confirm it and click Apply> Proceed to execute it.

After a while, the NTFS partition will be converted to Ext4 successfully. But Windows won’t recognize the Ext4 file system, thus the Ext4 formatted partition will not present in Windows File Explorer.
