Hi, Carlos. The scraper is the right tool for the job, you just need some instruction. This is kind of like getting a roll of Seran Wrap to start unrolling again after you have lost the end. The first thing is to find an edge. The best place is probably at a doorway where there is a metal threshhold over the edge of the linoleum. Remove the metal threshhold and an edge should be visible. Start prying genly from there and away you go. If you can't find an edge that way, you might have to remove the quarter round next to the base shoe molding. Start with small tools like pry bars to get and edge loose and when you have removed enough with the small tools you can start using the big scraper.
