New Hotfix:- Creating OSD USB deployment media in System Center Configuration Manager 2007 fails with "The parameter is incorrect"

If you are creating a lot of USB deployment media, then you’ll have come across this problem, I know that I have and no fix or explanation was offered, until now.


When trying to create Stand-alone media,
Bootable media, or Capture media on a USB Flash drive via the Microsoft
System Center Configuration Manager 2007 (ConfigMgr 2007) console, the Task Sequence Media Wizard fails with the following message:

Error creating media. Error message is: The parameter is incorrect.. Please refer to CreateTSMedia.log to get details.

Inspecting the CreateTsMedia.log shows the following errors:

Beginning media generation CreateTsMedia
Failed to create media (0x80070057) CreateTsMedia
CreateTsMedia failed with error 0x80070057, details=”” CreateTsMedia

Creating the USB media in a ConfigMgr 2007 console running on other PCs may be successful and may not reproduce the problem.


The problem is a known issue with ConfigMgr
2007 SP2 and older, including R2 and R3, when the following conditions
exist on the PC running the ConfigMgr 2007 console:

  1. A mapped network drive exists on the PC
  2. The PC’s hard drive has a partition with no drive letter attached to it

Condition #2 above is very common in Windows 7 and Windows Server
2008 R2 since the default installation of Windows 7 creates the boot
partition as a “hidden” system partition with no drive letter attached
to it. It is also a common configuration on PCs that have been encrypted
with BitLocker. For this reason the issue is seen most often on Windows
7, Windows Server 2008 R2, and PCs that have drives encrypted with


To work
around the problem, take one of the following two actions before trying
to create the USB media via the ConfigMgr 2007 console:

1. Temporarily disconnect mapped network drives.


2. Via the Computer Management console, temporarily assign a drive letter to the “hidden” partition.

Only one of the above two actions needs to be taken. Both do not need to be taken.

Once the USB media has been created, mapped network drives can be
reconnected and/or the assigned drive letter can be removed from the
previously hidden partition.
