Changing a drive letter in Windows 10 can be a straightforward process if you follow these steps. Whether you're reassigning an existing letter or adding one to a new drive, Disk Management is your go-to tool.
Important Note:
Be cautious when changing the drive letter of a drive that already contains Windows or apps. Doing so might cause these apps to malfunction or have trouble locating the drive.
Steps to Change or Add a Drive Letter:
Open Disk Management:
Right-click the Start menu or press Windows key + X and click on "Disk Management."
Locate the Drive:
In Disk Management, find the volume you want to change or add a drive letter to. Right-click on it and select "Change Drive Letter and Paths."
Change or Add the Drive Letter:
If you want to change the drive letter, select "Change."
If the drive doesn't already have a letter and you want to add one, select "Add."
Select the New Drive Letter:
Choose the new drive letter from the drop-down menu and click "OK." Confirm the change by selecting "Yes" when prompted about how this might affect programs relying on the drive letter.
Note:
If the "Change Drive Letter and Paths" option is not available or grayed out, the volume might not be ready for a drive letter assignment or it could be unallocated and need initialization. Additionally, some drives like EFI system partitions and recovery partitions might not be accessible for drive letter changes.
Following these steps will help you change or add a drive letter in Windows 10.
