I have 4 drives. I am running windows 2000 Pro on four partitions on one drive. I have installed OSS. After some months of running without issues I defraged all my drives. Oss flaked out. Won't boot to ANY partition. So I uninstalled it. I was then getting MBR error1. I ran a FIX MBR disk. I was able to boot to one partition and tried to reinstall OSS. Now it wont work and I can not boot to any partition. I uninstalled it again but still could not boot. I am sure that with all my playing around I have tangled the partitions. I have a Acronis Rescue Media disc and can load DD10 to edit the boot.ini files. I Was able to boot by setting what i think is partition 3 to active and pointing its boot.ini to partition 2. What i want to know is : 1] How can I use DD10 to Identify wich partition label is what partition # ? and 2] How do I point the individual boot.ini to the correct locations so as to ISOLATE them frome ach other.
