Archived - Boot Camp 3.0: Cannot Install Windows XP Service Pack 3

When attempting to install Service Pack 3 on a Windows XP computer running Boot Camp 3.0 (which is included with Mac OS X 10.6 Snow Leopard), the following Copy Error dialog box appears:

An error occured while copying file osloader.ntd.  Cannot copy file to destination directory.  Click Retry to retry the operation or click Cancel.

This article has been archived and is no longer updated by Apple.

This dialog box appears because Windows is attempting to write to the first partition it sees to install the update.  Using Boot Camp 3.0, the first partition it sees is the Mac OS X partition, which is mounted as read-only.  This is why the copy cannot complete.  In order to avoid the dialog box, complete the steps below to disable the OS X file system read feature so that the Windows partition is the first one that the update sees, then reinstall the update, then re-enable the OS X file system read feature.

Getting out of the Update installer

  1. Click Cancel to dismiss the Copy Error dialog box
  2. Another Copy Error dialog appears  "Do you want to continue setup without copying this file?"  Click No.  (If you clicked on Yes, the update will still fail with a copy error, click Cancel).
  3. A Service Pack 3 Setup Warning appears asking if you are sure you want to cancel.  Click Yes.
  4. A new Service Pack 3 Setup Error appears.  The filename, directory name, or volume label syntax is incorrect.  Click OK.
  5. Another Service Pack 3 Setup Error appears telling you the installation did not complete.  Click OK to undo the changes.  Windows will now back out the Service Pack.  If any delete errors occur, click on Cancel.  If asked to continue setup without copying a file, click No.
  6. You will eventually get a final Service Pack 3 Error message telling you that the installation did not complete.  Click OK.
  7. Click Close to dismiss the Installing Updates dialog.

  7. Click Start, then click on Shut Down.
  8. Click Restart to restart Windows XP.

Re-applying Service Pack 3

  1. To make sure you can't see the OS X partition, click Start, then My Computer.  You should not see Macintosh HD in Hard Disk Drives.

  3. Reinstall Service Pack 3.  The install should proceed normally now.
  4. When the Service Pack installation is complete, a window appears.  Click Close.
