Question : Problem: Windows update SP 3 failed on my iMac boot camp partition! How do I fix this?

I have an iMac 24 with Leopard and I'm in the process of setting up Windows XP using Boot Camp.   Everything is moving smootlhly until the driver install part on the XP side.  I put Leopard CD in and autorun starts the driver install but eventually it Blue screens.    I figured I would try the Windows update to see if I could get the drivers install that way and on SP3 update install, during that process it fails and says it's not enough space on the drive.
It's a 230 GB partition.  Why is it doing this?  How do I fix it?   I thought Windows could handle this size under SP2.  Please advise.

Wow, more digging and here is what I found...
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.
