======Extend C-drive Server 2008 VM======
Starting with Windows Vista/Server 2008 the OS installer creates a BDEdrive volume of about 300 MB containing the boot files. This BDEdrive is necessary to use BitLocker.

If you encounter a shortage of space on the C-drive of a Windows Server 2008 server and you add extra space to the VMDK file containing the C-drive, you'll notice that you can't extend the C-drive with the added space beccause the BDEdrive is in the way. \\
If you are not planning to use BitLocker you can follow the following steps to extend the C-drive:

  - Execute the following command in a command prompt: <code>bcdboot c:\windows /s c:</code> Output when succesful:<file>Boot files successfully created.</file>
  - Rightclick the C-drive in diskmgmt.msc and click on **Mark Partion as Active**.
  - Reboot the VM.
  - Remove the BDEdrive volume.
  - Extend the C-drive with the added space.
