Thanks, glad to hear that you liked the article, but there is not a missing step.

It is important not to confuse the drive and the file.

In the steps and in Figure E, I show you how to create a VHD file named Windows8RP.vhd. When you get to Figure G, you can see that the drive is unnamed. While the file contains the drive, the drive doesn't automatically inherit the file's name.

When we get to the Administrator Command Prompt shown in Figure K, we Attach the file which essentially brings the drive to life, but the drive, or more preceisely volume, itself is still unnamed.

Once Windows 8 is up and running, you can assign a name to the drive if you wish.
