A while back I rebuilt my laptop to use Windows 2008 Server. The main reason that I did it was so I could develop SharePoint applications on it rather than having to use a VM. At the time, I forgot to partition my hard drive so I could take advantage of BitLocker. Anyway, not to long ago the time can when I realised that I need to re-enable BitLocker. I thought that I was going to have to rebuild it. However, I spent 5 minutes searching the web and came across the BitLocker Drive Preparation Tool this tool does the following for you:
The BitLocker Drive Preparation Tool automates the following processes to make the computer ready for BitLocker:
•Creating the second volume that BitLocker requires
•Migrating the boot files to the new volume
•Making the volume an active volume
Once you have run the installation program a new utility called the BitLocker Drive Preparation Tool appears on you menus and once you have run it, rebooted a couple of times it allows you to enable BitLocker.
