I'm running the latest update of Leopard and Windows XP SP2 in a 20 GB FAT32 partition, on a 24" iMac Al (Fall 2007). I've been out of the country for the last 5 months, but when I left my computer, safe and sound at home, XP booted fine with Boot Camp. I had the latest Mac OS software as of August 2008. Now, I've returned and the first thing I did was Software update and refresh my system. I've tried to boot in Windows, and I got a black screen with a blinking white underscore on the top left corner - the operating system doesn't load. Does anyone know of any software updates that could have affected my Windows installation? I somehow doubt that, without use, the Windows installation managed to screw itself up, but I suppose it is Windows, isn't it? If anyone has any insights they would be greatly appreciated!
