I've opened terminal and type following commands :

# sudo mkdir -p /media/c
# sudo fdisk -1

Nothing happens when I press enter.

Let me back up a little. I am able to install Ubuntu 12.04 on my machine, but while going through installation, it says I have multiple operating Systems. Which I don't, but perhaps one of the 3 partitions looks like a seperate O.S. Therefore I'm trying to see what specifically is on the 1.46 GB partition(boot. diag) as well as the 13.75 partition (HDD recovery) and decide if I should delete one of them, or just move forward with install.

I have full Windows 7 OS on a USB, so I probably don't "really" need recovery. THe problem is windows labels the 1.46 partiton as recovery, while Ubuntu labels the 13.75 as recovery.... so I'm confused.

Often you have a Windows recovery and a vendor recovery. The Windows is to repair Windows, where vendor is an image of hard drive as purchased. But Windows recovery or repair is usually smaller with BIOS/MBR. Is this a UEFI with gpt partitioned system? –  oldfred Sep 23 '13 at 21:14
How would I check if this is a UEFI with GPT partitioned system? –  5th Wheel Sep 23 '13 at 21:19
The fdisk command you presented has -1 (digit 1) as an option, but that's invalid. You probably meant -l (lowercase L). This command won't mount the partition, but it will show you a list of available partitions, at least if you've got an MBR disk or a very recent version of fdisk. –  Rod Smith Sep 23 '13 at 22:24
@Rod Smith Thanks. I see that now. However I still get no response when typing #(space)sudo(space)fdisk(space)-l , and then hit enter. But, I guess my real intention is to mount the sda/3 partition to check it out, and I can't figure out how. –  5th Wheel Sep 23 '13 at 22:35
Just to be clear, you don't need to type a # sign before your commands. Try running sudo fdisk -l. There should be, at the very least, some output. –  SirCharlo Sep 26 '13 at 20:29
