Need help from PRo + guru! installation help!

[mingdaddy]

Hi, just a simple question. I have been looking at linux mint for a while and finally giving it a try!
I have a SSD with 120gb and a 500gb HHD. I partitioned 65G for my windows 7 and the rest for my linux mint.
I was trying to install the OS and it surprisingly occupied the entire drive and the progress bar seems to be stuck.
I picked 30G of Linux allocation upon installation and I have at least 50G for it.
Can someone please explain?

PS-> my disk is formated in NTSF

actually, another question. If i have two partition for my SSD and when I boot my PC will it allow me pick which OS?

Thank you so much!!!!
