[newbie] Installation Questions

[rotsorov]

1. I was asked during installation something like 1) remove windows 2) use
the current windows partition 3) create a new partition.  I want to keep
windows, so option 1 is out.   What is the difference between option 2 and
3?

2. I choose to use the current windows partition and it installed all but
the 3 minutes remaining and froze.

Any help is appreciated.
