If the original letter was taken from a new drive, change the letter of the new drive to another available letter, then assign the shared letter to the target drive.

In addition, partitions that are hidden by special technologies (for example, setting the partition type ID to 0x17) still do not have a letter.

If a partition is hidden, the “Change drive letter and paths” function is not available (grayed out) for this partition in Disk Management. At this stage, the best solution is to show the partition using third-party programs.
