Hey everyone, I’ve got a new 1TB drive and I’m on Windows 11. I wanna partition a hard drive on Windows 11 so I can keep Windows on one side and all my games/files on the other. I’m not very good with this stuff—what’s the simplest way to do it without losing my data? Anyone here done it before?

This can usually be easily and safely done using the Disk Management utility in Windows.

1

Right click your Start button and select 'Disk Management' on the resulting menu.

2

In the bottom pane of Disk Management, right click the C drive partition and select Shrink.

Wait for that process to query the drive on how much that partition can be shrunk by.

On the resulting dialog, you will see the amount the C drive partition can be shrunk by, the calculation used is 1000 = 1GB, so for example, 50,000 is 50Gb and 100,000 is 100GB

Set the amount you want for the new data partition and click the Shrink button

Then, wait for that operation to complete, do not interrupt that process.

3

That will result in an Unallocated Space on your drive, right click that and select 'New - Simple Volume', accept the defaults and then wait for that process to complete.

    Windows 11 has modern PowerShell cmdlets for disk management. This is cleaner than Diskpart because it's object-based and easier to script. You can save the script as .cmd and double click the file to partition a hard drive on Windows 11.

    # List all drives
Get-Disk

# Initialize the new disk (replace 1 with your disk number)
Initialize-Disk -Number 1 -PartitionStyle GPT

# Create a 500GB partition
New-Partition -DiskNumber 1 -Size 500GB -DriveLetter D | Format-Volume -FileSystem NTFS -NewFileSystemLabel "Games"

# Create another partition with the remaining space
New-Partition -DiskNumber 1 -UseMaximumSize -DriveLetter E | Format-Volume -FileSystem NTFS -NewFileSystemLabel "Files"

    This does the same as diskpart but in a single, more readable script.

    P.S. If you want a more user-friendly or advanced method (resize/move without limits), then a dedicated disk partition software is more recommended.

    For a new drive, the easiest way is to skip the technical stuff and use the built-in Windows Disk Management utility. I did this last month: I just shrank the existing big Windows partition from the right side and created a new, separate "Games" partition with the free space—super simple and no data loss!

    In fact, you can also partition a hard drive in Windows 11 using the command line with Diskpart. It's a bit more "bare metal" than Disk Management, but still straightforward if you're careful.

    First, start the diskpart disk partition utility and list all available on your Windows 11 computer:

    diskpart
list disk

    Select the disk (0 is the internal hard drive by default) to be partitioned with dispart command:

    select disk 1

    Create the first partition (say 500GB):

    create partition primary size=500000
format fs=ntfs quick label="Software" 
assign letter=D

    Create the second partition (use the rest of the space):

    create partition primary
format fs=ntfs quick label="Files"
assign letter=E

    You'll now have two partitions:

    D: (Software, ~500 GB)

    E: (Files, the rest of the drive)

    For tech savvy, this is one of the best ways to partition a hard drive in Windows 11 as far as I know.
