Windows 7 & TrueCrypt Full disk Encryption

Currently installing FDE using TrueCrypt is not possible on Windows 7 without doing some trickery before you install the OS on your drive.

1. Start the installation like normal
2. Make sure you customize your install, don't just let it do everything for you.
3. When it gets to the part where you choose your disk, click the "advanced" disk setup.
4. Delete all your partitions.
5. Click "New...", choose the maximum size possible for your drive. Click OK
6. It will tell you that "Windows may create a partition..." blah blah. Click OK. You'll see a 200 MB partition in addition to another partition with the rest of your space.
7. Now delete the larger partition leaving the 200MB partition intact.
8. Now select the 200MB partition and expand it to fill the space. Click OK to the warning.
9. Now you should have a single partition, go ahead and install windows the rest of the way.
10. Encrypt your drive as normal.
