You have to label a partition as the root - "/". If you don't have experince with manual partitioning, try the automatic partitioning option.

Here you got a install guide, just follow the steps

I have a new hard drive alongside my old one and I'm trying to install ubuntu in the new one. My corrupted Windows is in the old one. But I can't seem to find the button for automatic partitioning. –  Big Jim Oct 4 '13 at 20:02

Start to install Ubuntu and when it asks you if you want to replace or install next to or do something else, choose Do Something Else. Then create the following partitions. 1. a boot partition /boot and give it 250mb of space I would choose ext4 for the format 2. a root partition /root and give it 12000mb space and ext4 format 3. a swap partition /swap and give it 4096mb of space (it will format to swap) 4 a home partition /home and give it the rest of the space and format it to ext4. then continue your installtion.
