Hi, i wonder if there was and easier way to secure write access to a partition other than through file permission. im open to all ideas, i thought about encryption.

i will have two operating systems installed on separate partitions, one of them will be potentially unsafe, so i would like to limit all access to a partition, though preferably not policies implemented through the unsafe OS.

Do the two operating systems use the same filesystem? Actually, it might be easier to answer you if you told us which operating systems you are talking about, and which one of them needs to be secured (apparently from the other OS when it is running).

both are windows xp home.

essentially i need dual boot.

so access to the primary installation needs to be restricted, and possibly from the primary to the secondry partition.

i need a secure way to enforce disk access.

so there is no "host" or "guest". If you want to run one OS from inside the other, then you'll need to install XP into a VM with whatever virtualization solution you prefer.

If you just want a dual boot system, but you don't want to be able to access one XP partition from the other, you can encrypt each one as it is running. Do not encrypt both from the same running OS.

Here's something on dual booting two XP installations:
