Removing Bitlocker Volume (BDEDrive) from Windows Server 2008R2


I recently ran into a situation where I needed to add more Harddrive space to one of my Windows Server 2008 R2 virtual machines. Seemed simple enough, add some GBs to the drive in VMWare, get in Disk Management on the VM, right-click the volume and hit Extend.

Not so fast, I look in Disk Management and I have a 300mb Volume labeled BDEDrive. Because that volume is present I have no option to extend my system partition. A little googling yielded this result.

Apparently the template I use to deploy all my virtual machines has the 300mb volume even though Bitlocker is not running. Still not sure why that is, maybe it part of the default Windows Server 2k8 R2 install.

Anyway, to get rid of that 300mb volume do the following:

1. You might want to snapshot the VM before proceeding. I’ve done this about 20 times and never had a problem but you never know.

2. Open a CMD prompt as an Administrator

3. Type bcdboot c:\windows /s c:

4. Reboot the server

5. Get in Disk Management and delete the 300mb volume and you should now be able to extend the system partition.
