This is the situation: 1. I had Vista Business installed on my 80GB harddisk. 2. I installed Disk Director 10 on Vista machine and partitioned the Harddisk to 40 GB each. The second partition was created as Primary partition and named XP Pro and the drive as X:. 3. I installed OSS. 4. Then I hide the Vista partition and made the second XP Pro partition as Active and loaded my XP CD. OSS showed me the XP CD icon and booted through it. 5. XP has loaded, but I have lost Vista and am not able to get it despite all effort. I have re-activated OSS through XP but still I dont see Vista. Please help.
