Yes, you can create a new partition after Windows has been installed. There is no conflict, and you can separate the Windows system from other data by partitioning your drive. Thus, your data will become less likely to corrupt when the system collapses. For this reason, you can create partitions after Windows installation. Creating a partition is not like adding a file because any incorrect operation could cause damage to your data. To help you successfully partition your drive, I will introduce two excellent methods in the following part.

Fix 1: Reliable Partition Software

If you are looking for the easiest and safest way, EaseUS Partition Master can satisfy you by helping you create partitions effectively. Install this professional software on your computer and try it now as follows:

Windows 11/10/8/7100% Secure

Attention: Keep your data intact by backing it up in advance, or move the sensitive data to your external storage device like a USB drive.

A new partition should be created on the disk's unallocated space, so we start with how to create unallocated space. However, if your disk already has unallocated space, you can skip to step 3 to create partitions directly.

Step 1. Launch EaseUS Partition Master using the above tap, and right-click a partition with a lot of free space, choose "Resize/Move."

Step 2. Then drag any end of the partition right or left to shrink the partition size to add unallocated space. Click "OK" to apply.

Step 3. Head to the Partition Manager, right-click on the target disk's unallocated space to select "Create."

Step 4. Confirm the partition size, drive letter, partition label, file system, and so on in the Advanced Settings. Click "OK" to begin partitioning.

Step 5. Click "Execute 1 Task" and "Apply" to finish the partition process.

Fix 2: Windows Built-in Tool

Windows has also offered a reliable Disk Management tool to complete your disk partitioning task. Here is the specific guide:

  • Search and open Disk Management, right-click the unallocated space, and pick "New Simple Volume."
  • Accept the default settings or customize the size, drive letter, and file system, and click "Next" after each change.
  • When the above is done, click "Finish" to create a new partition.

If you want to create more than one partition, repeat the whole process. Check more information about creating disk partitions by the following link:
