How to Change Drive Letter Using Command Prompt in Windows

Sometimes, you may need to change a drive letter in Windows, and one of the quickest ways to do this is by using the Command Prompt. Here’s a step-by-step guide on how to accomplish this using Windows’ built-in commands.

Step 1: Open Command Prompt with Administrator Rights

To change a drive letter, you’ll need administrator privileges. Open Command Prompt by following these steps:

• Press Win + X and select “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.

Step 2: Start the Diskpart Utility

Once the Command Prompt opens, type the following command and press Enter:

diskpart

This command will launch the Diskpart utility, which is used for managing disks, partitions, and volumes.

Step 3: Display the List of Volumes

To view the available volumes and choose the one you want to modify, enter this command:

list volume

Diskpart will show a list of all volumes connected to your system, along with their drive letters and file systems. Locate the volume whose letter you want to change.

Step 4: Select the Volume

Next, select the volume whose drive letter you wish to change. Type the following command, replacing N with the volume number:

select volume N

For example, if your volume number is 2, type:

select volume 2

Step 5: Assign a New Drive Letter

After selecting the volume, use the assign command to assign a new drive letter. Enter the following command, replacing Y with your desired drive letter:

assign letter=Y

For instance, if you want to assign the letter D, type:

assign letter=D

Step 6: Confirm the Changes

To verify that the changes have been applied, enter the command once more:

list volume

You should see that the selected volume now has the new drive letter. Once confirmed, you can exit Diskpart by typing:

exit
