I was building Windows Server 2008 R2 SP1 64bit and created three drives (C, E, F) as drive letter.
I need to change "E" drive letter to "D" drive letter. I mean I do not see the "D" from the pull down menu, so I checked registry and found "\DosDevices\D:". I released the drive letter "D" by renaming it with other drive letter.
Reg location: HKEY_LOCAL_MACHINE\SYSTEM\
However, it still nothing changes...
Please advice me how I can assign D drive letter again.
