Not able to assign Drive Letter for System Reserved Partition in WS 2008 R2

    Question

  • Hello,

    I need to assign Drive Letter for  System Reserved Partition in WS 2008 R2. However, I am not able to do that. The options are greyed out. 

    Our organisation policy says, we need to assign the Drive Letter to system reserved partitions. On other WS 2008 R2 servers, I am able to assign the drive letter but not this one.

    How do I fix this issue ?

  • Well, you can assign the drive letter to Locked System Reserved Partition using DISKPART.

    Follow the instructions below

    from elevated cmd, run DISKPART

    from disk part run following commands

    DISKPART> select disk 0 

    You should see the message " Disk 0 is now the selected disk."

    DISKPART> list volume

    You should see the volume listed like below

      Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
      ----------  ---  -----------  -----  ----------  -------  ---------  --------
      Volume 0     D                 DVD-ROM            0 B      No Media
      Volume 1     C   LocalDisk  NTFS   Partition     67 GB   Healthy    Boot
      Volume 2     E   LocalDisk  NTFS   Partition     67 GB   Healthy    Pagefile
    Volume 3                       FAT32  Partition    200 MB  Healthy    System

    Say, Volume 3 is the system partiton, you can identify that very easily as that will not haveName assigned to drives such as LocalDisk

    Now, 

    DISKPART> select volume 3

    You should see the message "Volume 3 is the selected volume."

    then 

    DISKPART> assign letter=Z  ( Assign any Drive letter of your choice )

    You should see the message "DiskPart successfully assigned the drive letter or mount point." 

    Thats it !!!

    I tried this on my Test Server and it works. Hope that will help.

  • Hello,

    that system partition is required for BitLocker drive encryption and you cannot change it or add a drive letter AFAIK. If you don't like to have it you must do it during the installation and install the server without this partition.

  • Hello Meinolf,

    Thanks for the reply.

    In fact, System Reserved partition is needed and I would like to assign a drive letter.

    As I mentioned in my post, I have assigned drive letter to this partition on numerous other 2008 R2 servers but only on this server in question, all the options are locked out.

    For E.g.

  • Hello,

    thanks for the update, nice to know this. :-)

    Any chance that there is another OS like MAC in dual boot installed? Read somewhere that could be blocking the change.

    Answer is No. WS 2008 R2 is installed on a physical server.

    Absolutely Amazing !!! You saved my life !

    I ran the diskpart commands as suggsted and that worked for me.

    One observation though, I still can't see drive letter assigned for system Reserved Partition from Disk Management Console however, a Drive appaeared as I wanted in Computer :))
