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.
