Installing XP SP3 reports “There is not enough Disk space” on Apple

On an Apple Computer Microsoft XP SP3 Installer displays the error:

There is not enough disk space on C:\WINDOWS\$NtServicePackUninstall$ to install Service Pack 3 Setup requires an additional 4 megabytes of free space or if you also want to archive the files for uninstallation,Setup requires 4 additional megabytes of free space. Free additional space on your hard disk and then try again

This is Caused by the EFI system used in modern Apple computer systems – EFI is unsupported by Windows XP – a simple registry fix corrects the issues.

Begin by Clicking Start then Run – Type “regedit” and press enter.

Navigate to:

HKLM\Software\Microsoft\Windows\CurrentVersion\Setup

On the right side, Right-click and select New – String value

Set the Name to “BootDir” and set its value to “C:\”

Reboot and retry the SP3 Installation.
