When installing Ubuntu 13.04 Desktop, It doesn't show my second hard drive as an installation option. I am trying to install Ubuntu alongside Windows 7 on another hard drive. Windows 7 sees my second drive fine, and it is also listed in the bios. Another strange thing is that Install Ubuntu sees my first drive( the one I have Windows 7 on ) fine, but is says "No operating system detected". Please Help!
You may want to UNPLUG your Windows HDD and only leave your blank HDD plugged in then start the Ubuntu Live CD, I have seen Ubuntu not detect two HDD's before. That should solve any confusion. Then use your BIOS to choose between HDD's to boot.
