Second image is coming the right way. The strings on the bottom is because the heatbed is not levelled right. Or the speed of the first layer is too high. You need to get this first layer put down really, really well for the rest of the print to succeed. A height difference of 0.1mm determines make or fail for a great deal. Take a piece of paper and level it as explained elsewhere (google is your friend). Reduce the first layer speed to 20 mm/s max.

Also, you may need to consider the bed material. I and many others have good success with a glass plate and the right kind of hairspray. If you can't find the right kind of hairspray, then 3Dlac is excellent. I use 3Dlac all the time and it has never failed me. The glass plate can't be scratched/torn like tape or kapton, and you can wash off the hiarspray/3Dlac with warm water to get a perfectely clean heatbed again. Well worth the investment. Also the bottom layer becomes really smooth and shiny.
