Dear Acronians! I'm quite in despair here. I wanted to create a multi-boot system with Vista Home 64 and two XP Profs. I installed Vista and one XP, multi-boot worked smoothly. Now I made a backup of XP and installed it into a third partition. I tried to hide the systems from each other in OSS. Now it happens that all three boot-partitions are hidden. In OSS, the three systems are recognized, but each fail to boot with "autochk not found". In OSS I notice, that the boot-partitions of each boot-option are set to active AND hidden. Both options are grayed out, so I cannot uncheck "hidden". Writing this from a Linux System, which saved my life for the moment Any idea?
