Subflooring help for bamboo floors

Im installing bamboo floors, everything that i read said that particle board in unacceptable as a sub floor so i plan on ripping that out today, but what do i put in its place? Im installing solid bamboo on top and have read a million articles saying as long as its ps2 that OSB can be used, but the other things i have read is that there will be a lot of lifting because the OSB does not hold nails well. HELP!!!

OSB is good but AdvanTech or plywood is better.

With the particle board removed, what do you have left underneath?

So what in thinking is the plywood is my sub floor and the tar paper is a moisture barrier and for some reason they put parttical board underneath the carpet padding. With that being said it looks like the floor is way lower in the other connecting room including the kitchen with has tile why would that be?

Add 3/4" Advantech or similar underlayment. The 3/4" thickness is the key as it is the minimal thickness recommended for a nail down floor. Start by screwing your existing plywood down to the floor joists. Install the Advantech by staggering the joints and screwing to the plywood (not the joists), Then install 15# felt paper and the bamboo nailed over that. Particle board definitely needs to go - it is susceptible to water damage/swelling and it does not hold a nail sufficiently for a nail down floor.
