Windows usually automatically assigns the drive letters for the partitions. Letters A and B are designed for the floppy drive and tape drives. For the system partition, the letter is typically assigned as C. Other partitions on your hard drive, USB drive, optical drive, or card reader will also be assigned a drive letter by Windows.


Assigning letters to drives in alphabetical order is an easy way to keep them organized. However, in Windows, the letters allocated to your hard disks, optical drives, and USB devices are not fixed. You may want to change drive letter for certain reasons.

You can change a drive letter for better and easier recognition of your programs or personal files. Another case is when you have connected an external drive, and Windows gives it an already-assigned letter. You will need to change the letter in this situation. Now, read this article from EaseUS to learn more information about changing drive letters for a PC or laptop.

Is It Safe to Change Drive Letter

It is safe to change a drive letter, but there are risks. Changing letters for drives is simply a way to identify different partitions by different letters. However, the incorrect operation will bring you troublesome issues. Below are two main problems that changing drive letters can cause.

  • Changing the letter of a drive with installed software will cause the software to be unable to work. You might need to reinstall the software if you have done this.
  • The operating system may be unable to find your files. Windows operating system might be confused about where your files are located if you change the letter.

Pro Tip: Do Not Change the OS Drive Letter

It is not recommended to change the drive letter where the Windows is installed. Doing so can cause serious consequences to your computer.

  • If you change the OS drive letter, Windows will not be able to boot up because the corresponding encrypted files cannot be changed.
  • If you try to change it with Disk Management, you will see a message saying, "Some programs that rely on drive letters might not run properly."

Thus, if you do need to install Windows systems on another drive with a different letter, you must first perform a fresh install of Windows. Yet still, it is not a recommended thing to operate.


Above all the methods mentioned in this post, using a third-party tool like EaseUS Partition Master is certainly the easiest and safest way to change drive letters. Before you execute the changing process, you should always be careful with the drives you want to change letters for. An incorrect operation will cause critical results, and you might lose important data and programs.
