Having issues removing old tile

I recently started a project to do new floors throughout a house I just bought. We are gonna do about 1600 sq ft in total including the kitchen 2 living rooms, dinning room, and hall. Previously the floors were linoleum that I ripped up and part of the house was the slab concrete and a area in the kitchen, the dinning room and front door entry way are old tile that the original owners probably installed. I tried to get the tiles up using a hammer and chisel but only succeeded in breaking the edges and was unable to get underneath the tile to break it up. At this point I was thinking of floating the living room up to where the tile is to level it to install a wood vinyl hybrid. The other side I may be able to use leveling compound to gradually increase the height to where the tile is. The old linoleum was just put on top and you could tell the areas that were not level in one side of the dinning room and the other side they installed carpet to deal with this issue. I am searching for options in either raising the subfloor or ways to get up old tile which may be porcelain, I am not fully sure but I know it is difficult to get up.
