I've tried slip-streaming just a few hotfixes with SP3 integration using the latest nLite. When booting from the ISO, I get this message- "This operation could not be completed" that message blinks for just a nanosecond after I see the Setup is being restarted (attached) Then the computer reboots and does the same thing over and over... I downloaded all of the hotfixes for May 2009 (from catalog.update.microsoft.com) and just applied them along with the slipstreamed SP3 Did I miss something on how to properly install/integrate the hotfixes? I also tested, SP3 slipstreamed by itself works great! But I'm looking to add more updates/hotfixes to speed up the total time it takes to install XP. Any help and tips would be appreciated -Mac
