5. To Change a Drive Letter
NOTE: You cannot change a drive letter if the drive is either a system partition or a boot partition, like the partition or drive that Windows 7 is installed on.

B) Click on the Change button.
 
C) Select (dot) Assign the following drive letter, then select an available drive letter from the drop down box and click on OK.
 
D) Click on Yes to confirm changing the drive letter.
 
E) If you get a AutoPlay pop-up window afterwards, then you can just close this. It indicates that the drive, partition, or volume has been assigned the drive letter.
F) Go to step 8.
6. To Add a Drive Letter
NOTE: This is to assign a drive letter to a drive, partition, or volume if a drive letter has been removed or does not already have one assigned to it.

B) Click on the Add button. C) Select (dot) Assign the following drive letter, then select an available drive letter from the drop down box and click on OK.

D) Go to step 8.

A) Right click on a listed drive, partition, or volume letter that you want to remove the drive letter of, and click on Change Drive Letter and Paths.
