[Help] Formatted my hard drives.

[Bobca]

I accidentally formatted my hard drives while I was formatting my computer.

SATA : seagate barracuda7200.10 320Gbytes

I don't know how it work and I don't know basics on my computer :p

Your post is unclear. You don't format a computer, you format a hard drive - so it sounds as though you did want to perform a format. And it is virtually impossible to format your system drive accidentally - you have to verify / approve the command multiple times before the system will do it. Please explain exactly what you did IN DETAIL and explain what it is you want to do now.

I wanted to formate my computer, like I just bought it. So I used a USB key that I changed into a bootable device which I changed into my BIOS settings, in a part of the format windows asked me which hard drive I wanted to delete and I selected them all by accident and as I remember one had the description named "System" after I changed the page my computer restarted and I kept getting stuck at the boot page, I removed my SATA and it started normally and than it freeze. I'm stuck there:/

Also I don't have a second Pc.

It's still not completely clear, but if I understand what you did you'll need to reinstall the OS. Boot to a Windows disc and start the installation procedure.
