(Note: Replace "c:" with the letter of the drive that the boot folder was installed on.)

After running this command, you should be able to select and delete the BCD boot folder in Windows Explorer.

Other changes

Those who pay close attention to the file system will at first be confused by the new namespace. Remember the Documents and Settings folder in previous versions of Windows? It's gone, replaced with the Users, which serves a similar purpose, so that your files by default are stored in \Users\username, instead of \Documents and Settings\username. To confuse you even more, there appears to be a Documents and Settings folder in Vista, but in fact, it doesn't exist -- it's essentially an alias to Users so that programs that expect to see Documents and Settings will still work properly.

Microsoft has also gone halfway toward eliminating file menus throughout Windows Vista, and this inconsistency can be disconcerting. Menus are gone in Windows Explorer, Internet Explorer, and Windows Photo Gallery, for example, but are still there in Windows Mail, Windows Calendar, Notepad, WordPad, and a variety of other applications.
