Archived - Intel-based Mac: Startup issues after using unsupported version of Windows installer via Boot Camp

This article has been archived and is no longer updated by Apple.

Symptoms

An Intel-based Mac may not be able to start up after attempting to install an unsupported version of Microsoft Windows XP via Boot Camp. In this situation, your Intel-based Mac may not be able to start from Mac OS X even if you hold the Option key during startup, and the hard disk may not be accessible in FireWire Target Disk Mode.

Resolution

Please check your version of Microsoft Windows carefully before attempting to install it via Boot Camp. These versions of Windows are supported on Intel-based Macs with Boot Camp (the issue does not occur with these):

  • Microsoft Windows XP Home or Professional Service Pack 2
  • Windows Vista Home Basic
  • Windows Vista Home Premium
  • Windows Vista Business
  • Windows Vista Ultimate

If you are affected by this issue, you may be able to change the behavior by following the steps in Mac OS X: Disk Utility - All options dimmed for a disk that was formatted as NTFS in Microsoft Windows XP.
