You may experience the following error when installing Windows XP Service Pack 3 (SP3) when installing on Intel iMAC using Bootcamp to run Windows XP.
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 happens because iMac uses EFI file format which Windows XP does not support. To workaround this problem, add a registry key as follows:
1. Click Start – Run – Type “regedit” and press enter.
2. Navigate to
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup]
HKEY_LOCAL_MACHINE
\Software
\Microsoft
\Windows
\CurrentVersion
\Setup
3. In the right pane, Right-click and select New – String value4. Name it as “BootDir” and set its value to “C:\”
This should help. Try installing SP3 and should work fine.

Thanks! Worked for me too on a Mac Mini!
Thank you, I am also running XP with Boot Camp on a Mac Pro. This works a treat, I never had the problem installing XP on my Mac Book Pro though? Strange.
Brilliant, many thanks for figuring this out and posting it. After a couple of years of getting annoyed with the update, this finally did the trick!
Awesome! Worked on a non Mac laptop that had the hard drive formatted on a Mac.
Wonder why Microsoft doesn’t have this down as a fix for the problem.
Thanks! This did the trick for me. XP on Mac Book Pro.
Yep I thank you too..Worked like a charm

Hey, great advice! That worked like so awesome. Keep up the good work.
Worked like a charm for SP2 on new iMac. Thank you!
Worked on MacBook Air. Sweet! Thank you and thanks to Google!
core2duo iMac. Cheers, mate. This solution should be on apples bootcamp support site.
My kids have a Mac mini that they wanted to run Windows on for certain things. I am a great computer user but not much on the inside workings of one. Nevertheless, I installed Windows XP Professional Svc Pk 2 on it and it would not let me set up internet. My hubby, a computer security engineer, said I needed Svc Pk 3 for WPA2. I tried to install but got that stupid message. Hubby, who is always at work so can’t help much at home, said to Google the message. I found this site. I followed the instructions exactly as you wrote them, and it worked for me! Thanks so much for the solution. Now, if I can just get the internet to work, all will be well.
It’s working! Even as I comment.
I’ve found out in consulting to developer groups, there’s always ‘The Guy’, the one guy in the group that actually knows how everything works. You are ‘The Guy’ in this particular domain. Thanks.
Brilliant vistafix! Thank you – worked like a charm
Thank you very much! This worked great!

ps. works with service pack 2 not enough disk space error to. thanks again
Huge thanks. Very late night last night fighting windows 7 on MBP needing previous install and SP2 but SP2/3 not installng and only firewire network connections so no Online Updates
Perfect, worked exactly as specified. I suppose because you’re telling any setup to use c:\ drive specifically.
Your “fix” worked perfectly. I had pretty well given up on ever installing SP3. Thank you.
Regards,
Ted
Brilliant Work on Mac mini mid 2007 2GB with WinXP SP3
