6. With Linux you can set new partitions and format

anyway you want or just do the auto setup which sets partitions (root and swap) and formats automatically.
If there's one thing I do manually it's chose my own partitions. I like to make a separate root, home, var (variables) swap and another that I use for storing stuff. If one part of the system gets borked, usually root or var, I can reinstall the root and var and not format my saved stuff or home. If they're all one partition you can lose all of it. Var is a file where all variable short term files are written and rewritten by programs. Many times when something goes wrong it's the temp files used by programs in var. I keep it separate so I can fix problems without messing with anything else. You're ok hitting auto though. I just like making things complicated.
