I ran into the scenario a little while ago so I thought I would post the results:

• Power off the switch (un-plug it)
• Power it back on while holding the ‘mode’ button
• You’ll go into bypass mode
• In bypass mode run the following:
  • > flash_init
  • > load_helper
• > dir flash:
• remove the config.text
• rename the config.text using rename flash:config.txt flash:config.old
• use boot to complete the task

Your old configuration is now gone and you can start off fresh. Remember to go to conf t, and set the the enable password. Also be sure to use service password to encrypt the password.
