When I got my iMac, one of the first things I did was to fire up BootCamp and install XP, so I could use it for games. I've not been back to XP for a while, but when I tried to boot into Windows today, I hit a snag. If I hold down the Option key, the two boot options come up. I highlight the Windows partition and click the arrow underneath, to boot into XP, but the system just does nothing. After about five minutes, it does a 'soft reboot' and loads OS X instead. It's not a huge problem as I rarely use XP now, but I'd still like to be able to play a few games every now and then.... Any ideas, please ?
