I'm getting ready to install 3/4 oak hardwood in my kitchen. I have a laminate wood floating floor down now and just had new cabinets installed and there bigger then the old ones. The front of the cabinets sit on the floating floor. My problem is I can get the floating floor up because there's no room to get a saw or anything under by the toe board on the cabinet to cut out the wood that the cabinets sit on so can I lay down my felt paper and install the 3/4 hardwood over top of my floating floor as long as the nails go though the 3/4 new hardwood and the floating wood floor into the subfloor? I have a wood subfloor. I hope I'm making sense. I didn't know at the time when I had the cabinets installed I was going to lay hardwood down.

The nails won't be long enough to go through the toungue of the 3/4", the floating floor into the subfloor.

Do you own a rotozip? Rotozip has an angle attachment that you can put a cut off wheel on. This will fit under your toekick. Even if it laevaes a 1/2" of floating floor you can but the hardwood to the old floor and install 3/4" quarter round.

Also what may work is a recipocating saw (sawsall) with a 12" blade. You can curve the blade under the toekick.

The last option I can come up with is nail/screw your floating floor to the subfloor so it doesn't float. Secure it well. Now you have another subfloor.
