If the system you're using has EFI type BIOS, you may need to try setting a "legacy mode" option.

This Ask Ubuntu post has some clarification on the subject

This ubuntu help doc talks more about EFI and installing Ubuntu

https://help.ubuntu.com/community/UEFI

This person was able to resolve their booting issue by making sure they had the 64bit version

Hope some of this helps. Let us know what happens and we'll go from there.

I have UEFI, but I assume they're the same thing.

In the second link I found

"Having a PC with EFI firmware does not mean that you need to install Ubuntu in EFI mode. What is important is below:

if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too."

My copy of Windows 7 was installed with UEFI mode sooo....
