I have a unique situation on my hands and I'm not sure if there's a way out of it. Skip to the end for the problem. Here it is: -Bought Mac Mini server in 2011. Learned to use and love OS X. -Except it doesn't run certain Windows-only applications, mostly games. I decided to use boot camp and set up Windows 7. -I partitioned the server HD in half and installed Windows 7 on one of them. The machine now has OS X 10.8.3 and Windows 7. I can play those games. All is well. -Then I encountered a game made for Windows 98. I bought this game, hoping to run it on my new Win 7 install. It won't run on Windows 7 in any mode. My solution is to run it on Windows XP. -I free up 10 GB of space from the Windows 7 partition and try to install Windows XP on it. After some troubleshooting I finally got setup to run and it finished without errors. The Problem: Now, when I select my Windows HD at the boot screen it presents a system configuration error. I suspect it's checking for a boot.ini or some such, but I can't get to any of the usual BIOS stuff because this ain't a native Windows machine. Is there a way to get XP to show up as a separate selectable HD at the boot menu in OS X (when I hold Alt at startup)? Or, failing that, is there a way to get Windows 7 to load properly again?
