I had a dual boot using Windows 7 and Windows 8 Consumer Preview.

As I've decided to remove the Windows 8 Consumer Preview, I will share info on how to safely remove the dual boot using Bcdedit command.

Type bcdedit and hit Enter

You should see the list of entries for the dual boot configuration.

Find the entry for the Windows 8 Consumer Preview OS and check the identifier line. As you can see from the picture below in my case identifier was {default}
