Is there anyway for OSS not to keep changing the MBR everytime I have a different OS boot. It will keep setting the last booted partition as the Active partition. Is there anyway to stop this from happening? Example: You have P1 & P2. When booting to P1, you have it set to be active and P2 to be hidden. When booting to P2, you have it set to be Active and P1 to be hidden. You boot to P1 than you boot to P2. If you go into DD bootable CD, you will see P2 as being active and P1 as hidden. I want P1 to stay as the active partition and P2 to be hidden.
