Whenever I startup from the LinuxLive USB, and try to install Ubuntu 12.04, it only gives me two options instead of the usual 3 or 4. My options are "Replace Windows 7 with Ubuntu" and "Something Else". Whenever I go into "Something else", it looks extremely confusing. How do I install it side-by-side while using the "Something else" section? These are my partitions.
/dev/sda
/dev/sda1 ntfs (104Mb, System Required Partition)
/dev/sda2 ntfs (1000097Mb, Windows 7 Partition)
Or should I try reinstalling my installer on a CD rather than USB and maybe then it will have the "Install alongside" function?

Usually, Ubuntu's installer gives you the option to shrink your Windows partition and install alongside it. In your case, that option did not appear. This sometimes happens, and possible causes include:
chkdsk
in Windows.Since you're running Windows 7 (this also applies to Windows Vista, and to the corresponding Server versions, and will apply to Windows 8 as well), you can try to shrink the Windows partition using Windows, and then try again to install Ubuntu.
To do this, right click My Computer (sometimes just Computer) on the desktop or Start Menu in Windows and click Manage. Go to Disk Management.
(Alternatively, enter
diskmgmt.msc
into the text box in the Start Menu and press enter.)Then you can use Disk Management to attempt to shrink your Windows partition. It will schedule the operation for when the system is shut down, so that even files that are in use when the system is running can be moved.
However, system files marked immovable still usually will not be moved in this way. So you may need to disable hibernation, and even disable swap (i.e., the page file), in order to make this succeed. (You can re-enable them afterwards.)
As Mitch says, it's advisable to ensure all backups of documents and other important files are current, before dynamically resizing a partition (no matter how you do it).
