Unattended Uninstall of an an Instance

[Database Administrator]

How do I uninstall an instance of SQL Server 2005 from the command prompt
unattended?
The following command line give me the error "Microsoft SQL Server 2005
Setup was unable to install on your computer."

"C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\Setup.exe"
/Action=Uninstall /FEATURES=SQL /INSTANCENAME=MyInstance

I have found an article with the following command but it brings up all
instance names. Is there a way to provide an instance name to this command
line?

"C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\ARPWrapper.exe"
/Remove
