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.

By any chance, are the two HDD's connected to the motherboard using separate ribbon cables or are they piggybacked to one? A lot of times certain systems won't detect the second piggybacked HDD. – seanthewebber Jun 21 '13 at 4:33
No, they are separate. – Robobro911 Jun 21 '13 at 15:17
By the way, I am using a live USB, not a CD, in case that helps. – Robobro911 Jun 21 '13 at 15:20
Also, the drive I am trying to install Ubuntu on is older, and is IDE. The other drive( with windows 7 ) is SATA. – Robobro911 Jun 21 '13 at 17:12
Alright.. If you to unplug the Windows SATA HDD, then does Ununtu see your IDE HDD? – seanthewebber Jun 21 '13 at 21:50
