I am easily confused; however, please clarify: 1. Did you attempt to set-up a dual boot system consisting of a. XP Home b. XP Professional? If so, why? They are exactly the same operating system with some enhancements built in to the Professional version, mainly networking and security stuff.
That question asked, check your boot path (s):
1. Start/Run [or any other Command Prompt]/type "msconfig" (minus quote marks), and click "OK".
2. When the "System Configuration Utility" opens, click the "Boot.ini" Tab.
3. Click the "Check all boot paths" button.
