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 value

4. Name it as “BootDir” and set its value to “C:\”

This should help. Try installing SP3 and should work fine.

  33. Just wanted to add my own “thanks” to the very long list here.

    Couldn’t figure out for the life of me wth windows was complaining about – I had bootcamp set up a 32GB partition on my macbook, and most of it is still empty. Punched in “Windows XP SP3 out of space” into the mysterious google machine which pointed the way to your post.

    Installing SP3 now, thanks!

  34. You are Greatttttttttt Its working good !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  36. You are the MAN! This worked great and saved me from having to buy a PC or another copy of windows!

  37. Thank you! it worked on my iMac

  39. AWESOME! Thank you so much! This worked like a charm on my new MacBook.

  40. Hey Thanks! You just got me a client! But anyone knows what does this do?

    (Sorry for my bad english)

  41. This workaround is unnecessary, download the Bootcamp 2.1 update BEFORE you install SP3. http://www.apple.com/support/bootcamp

    Not doing this means you are risking instability.

  42. It helped. thanks a lot.

  43. I took this advice and applied it to my Windows PC and it worked. I have tried finding info to fix this problem all day. Why oh why didn’t I think of checking with a mac user first. With 3 other machines (all macs) here at the Inn, I’ll be glad for the day when I can dump this one problem child.

  44. It worked for me also.
    Just great,
    thanks

  45. Confirmed working through Parallels 3.0-5608 running a boot camp installation of Windows XP SP2 on a Mac Pro!

  46. I get the same error message, but I am using an HP Pavilion mx 70 with XP SP2 installed. Any help would be appreciated.
    (I installed a new hard drive, 80 GB, so there is plenty of hard drive space available.)

  47. I love you

  48. YOU SAVED MY LIFE! THANK YOU SOOOOOO MUCH, if at all possibly if would take you out to a nice fancy dinner and a movie…but alas…it was not meant to be
