When you dual boot multiple operating systems — such as Vista and Windows XP — you can easily configure the default boot operating system. In the case of Vista and Windows XP, you need to set the default boot operating system from within Vista.

To set the default boot operating system within Vista:

  1. Right click the Computer icon on your desktop and select Properties.
  2. Click Advanced System Settings.
  3. Click the Settings button under Startup and Recovery.
  4. Use the drop down arrow under Default Operating System to select the operating system you want to use.
  5. Click OK.
