Hello, I have a triple OS situation setup as follows: -Vista 32 installed first on part. A -then hid this part. and installed XP on part. B -then hid this part. also and installed another XP on part. C After all this I unhid all partitions, booted Vista and installed OSS. Now I have the problem that OSS detects and boots Vista but none of the XP's. It says "Unknown Operating System" for them and when trying to boot eather of them it says "File system not supported" or something ... ? Please help. Thx in advance.
