Server 2008 - Forces boot to Secondary Plex

Server 2008 (not R2) x64 at SP2.

Server had software RAID 1 (mirror).  First disk went bad and was removed.  We DO NOT want to replace it.  We want to run as single-disk system going forward.

System was booted to the Secondary Plex.  In the Disk Manager console, the mirror was removed and the missing disk entry was removed.  Remaining disk shows as single non-mirred volume now.

PROBLEM:  Even though there is only 1 disk now, and the mirror set was removed, the system requires selecting Secondary Plex to boot.  At bootup, the system still displays the 2 options--

Windows Server 2008
Windows Server 2008 - Secondary Plex

This requires manual intervention to select Secondary Plex at bootup.  System will not boot to first option, and displays a message about a missing disk.  We have to go back and manually choose Secondary Plex to boot.

How do we make (what was) the 2nd disk, no longer be listed as Secondary Plex so the system will boot normally as a single-disk system?

Yes, but how do I get rid of the extra (left-over) entry at bootup?  I found some articles on bcdedit but can't find a way to delete the extra entry because there are 2 with the same GUID.  

C:\Boot>bcdedit /enum

Ok-- answering my own question.  I used bcdedit to:

1)  Change the description of the entry named {current} to "Microsoft Windows Server 2008"
2)  Delete the entry named {default}

System boots normally now with a single disk and no "boot selection" screen.
