I am trying to make my laptop dual boot Ubuntu and windows 7. I have read several tutorials out there and once dabbled with Linux distros years ago before there really was any tutorials, guides, etc. to help me.
So anyways, I have a machine with 2 hard drives. Both are 698 gig drives. The first one has windows 7 on it and the partitions on it for recovery, hp tools, etc. It has 4 partitions on it already, but I wanted to install Ubuntu on the 2nd hard drive anyway. The 2nd hard drive has nothing at all on it. I never kept any data or anything on it. So when I run the Ubuntu installation off of my USB drive and select to set up my partitions for the installation myself (rather than letting it overwrite or install side by side) it only shows sdc which is the drive I wanted to install on.
I did not expect to see the other drive because it has 4 primary partitions on it already anyhow. The problem (or may not be I'm just concerned) is that it says sdc has 750 gig. However, that drive is only 698 max. It did say that sdc has 14 gig already used which is what windows and Gparted show me too. It did say it would unmount it during installation. So I'm pretty sure its the correct drive, but I'm confused about the 750 gig.

I do not want the installation to accidentally start messing with my windows 7 installation and files on the other hard drive. Another source of confusion is when I'm looking with Gparted, I expected the first hard drive with the windows 7 installation to show sda1, sda2, etc. for the installation, data, hp tools, recovery, etc. like tutorials on-line show me it should do. However like HP tools is showing up as sdd and the recovery is sdb. While the 2nd hard drive is sdc, not the sdb like I thought it should be named.

Anyway, I know I'm more of a newbie but still... I just want to be sure, then I can start learning more; now that there is so many more guides out there than there were 10 years ago.

Edit your question, and add the output from terminal of sudo fdisk -lu to your question. –  Gediminas Jeremiah Gudelis Aug 1 '13 at 17:17

It's calculational "problem".

Hard Disk Creators are calculating with 1000 and computer with 1024.

750*1000^3 = 750.000.000.000 Bytes 750.000.000.000 Bytes / 1024^3 = rd. 698,5 GiB (Gigabit binary Bytes)

i didn't read the rest of your text, because it's too long.

have a look on your hdd , I guess it's written 750GB on it, since there are no 698GB disk out.
