So as one can guess from this thread's name, it's another Boot Camp problem. I am aware that this is probably a question that has been asked many times before so no flaming, please >.< Ok lets get to the problem, I have a MacBook Air 11" Mid 2011 with Mac OS X Lion. I already have Windows XP Professional SP3 and I want to boot it up using my Mac. I've already put all the necessary files onto a 4 GB flash drive and partitioned my hard drive. The problem is that Boot Camp won't load BOOTMGR. I have tried the procedure that the Boot Camp Installation and Setup Guide mentioned several times already, but I still keep getting the same error: "Booting from Boot Camp Assistant created USB Drive...Failed to load BOOTMGR" Is there any way for me to successfully install Windows?
