Ubuntu installation problems

[Caipenghui]

I have installed windows and allocated disk space for ubuntu. When I installed Ubuntu, I saw that there are two options, one is coexistence with Windows, and the other is another partition. What is the difference between the first option and other partitions?

Which one should I choose?
I see a lot of people on the web choosing other partition options to divide disk space.

Will the coexistence option with windows be automatically partitioned?
