I'm trying to install Kali Linux dual boot with windows 8.1. During installation, only two partitiones: while I have 3 different partitions . Please help.
I guess you have GPT table and Kali can't manage them while installation. If you use
parted /dev/sda print you'd see all of your partitions.
To fix it, you should wait Kali fixes its installer (or maybe there are some patch/tricks available, I don't know Kali)
