I'm pretty new to Linux, but over the past few days I've taken it upon myself to give it a shot. I'm trying a few different distributions just to kind of get a feel for different versions, and this is the only thing that's really got me hung up.
I started with Windows 7, then I installed Ubuntu 13.10 (which works perfectly), and then I installed Linux Mint. However, I don't have a way to boot Linux Mint, and that's what I'd like to accomplish. My goal is to have a Linux Mint menu entry on the Grub2 menu that appears on startup to goes along with the Ubuntu and Windows 7 menu entries (and a few others that I have yet to use, like the Advanced Ubuntu Options submenu, and the memtest menu entry).
In case any of this information is needed, here's some information from the GParted partition table, as well as parts of the bootinfoscript output:
Partitions info and descriptions taken from GParted:
/dev/sda1is a 101.94 MiB primary partition with fat16 file system with a flag of "diag"/dev/sda2is a 11.29 GiB primary partition with ntfs file system with a flag of "boot" and a label of "RECOVERY." According to/boot/grub/grub.cfg, this is where the Windows 7 loader resides. I have no issues booting into Windows 7 from the current Grub2 menu./dev/sda3is a 275.12 GiB primary partition with ntfs file system with a label of "OS." This partition holds all of my files that were originally made on Windows, though some have been saved over using Ubuntu programs (nothing went wrong editing files across operating systems so far but let me know if this is bad for whatever reason)./dev/sda4is a 171.01 GiB extended partition. This partition is currently mounted. This contains the swap partition, in addition to logical partitions for the Ubuntu 13.10 and Linux Mint 16:/dev/sda5is a 58.79 GiB logical partition with ext4 file system, which contains the installation of Linux Mint 16. In GParted, it says the mount point for this file system is/. This is the only partition that has a non-empty mount point entry. I don't know what to make of that, and I also currently do not know of a way to boot Linux Mint 16 as it currently resides./dev/sda6is a 19.56 GiB partition (I believe it's considered primary?) with "linux-swap" file system. This was created automatically when I installed Ubuntu, but I increased its size manually by about 10 GB when I was having a few issues trying to install Linux Mint 16. Linux Mint 16 is currently successfully installed as far as I can tell, but I don't know how to boot into it like I said before. This partition is currently mounted./dev/sda7is a 36.41 GiB logical partition with ext4 file system, which contains Ubuntu 13.10. Ubuntu 13.10 works quite well, and it's what I'm currently writing this question in. This partition is currently mounted.
Here is the bootinfoscript output (it's quite long, and includes the grub.cfg file as well as the sudo fdisk -l info already posted here - some had to be omitted due to character limitations, however):

--------------------------------------------------------------------------------I'm not sure if this partition setup is good or not, because I was unable to create an additional primary partition (4 max), but I figured since Ubuntu could boot from within the extended partition, Linux Mint should be able to as well, so I added Linux Mint to a partition in the same extended partition as Ubuntu (which is in /dev/sda5), but in its own logical partition /dev/sda7.
In the /boot/grub/grub.cfg file, there are several menuentry units. If the right way to go about booting Linux Mint from the Grub2 menu is to just add a menuentry block for Linux Mint, then I'd like to know how to do this. If there's a better way to get each of these operating systems to have an option to be booted on startup, let me know that as well!
I saw a somewhat similar question here but it seemed a little bit different since that user didn't have two operating system partitions contained within the same extended partition, and I didn't want to just be shooting in the dark and possibly break something important by accident.
If any more information is needed that I haven't given here, I'll be keeping a close eye on this so let me know right away and I'll do my best to provide you with whatever info you need.
Thank you very much for any help!

You could try update-grub to see if that will detect Linux Mint. This should check to see what operating systems are installed.
Alternatively, you could try booting off the live USB (or LiveCD) and running grub-install /dev/sda with the hard drive mounted. This will reinstall GRUB and should check for other operating systems again.
