I have a 500 GB hard drive. The laptop came with Windows 7 preinstalled.

Now as I am installing Windows 8, **I have deleted the C drive**. So I have 460 GB free unused space where I can install Windows 8.

But the Windows 8 installer **does not give me any option** to partition the 460 GB.
The only option available are "**Refresh**" and "**Load driver**" or just selecting the 460 GB HDD and installing Windows 8 in it.

**So how can I partition this 460 GB before I install Windows 8 in it?**

**Edit**: Can you suggest me some tools that partition the hard drive and **RUN independently** (as I do not have any OS installed) from a USB ?
