Well everyone I apprieciate your responses and help , thanks. I had actually responed myself yesterday giving more info on this and for some reason i am not exactly sure but obviously I forgot to actually press the "submit reply" button. So that entire message i wrote never posted ....Doh!, Homer said! So anyways I am gonna try this again .
Ok , before all this happened I had Linux Mint 17 KDE running/installed to an 80GB Hard Drive, (which was on sda1)and as the Boot info script shows , I have 2 other hard drives and they are both identical in size and and all ...36GB or something and those I just used as extra memory and stored backup files on and some Android Rom developmnet stuff I mess with ...u get the picture . So, I have no clue what happened but came turned the computer on and instead of booting I just get the grub>screen . So I have tried using the Boot--Repair live dvd as Arcane mentioned to no avail. I tried using a bootable partition manager by minitool, that didnt work either . I also followed Vincix recommendations....

So there is the output of some of that. I also just FYI ---I dont know what happend like i said but before this happend when I would open the file manager and browse , the "main" hard drive that I had Linux installed on was always identified in the file manager as sda1. Then when this happend , i look in the file manager and it now it says "LOOP DEVICE"?? What would make it change to that? And in the boot info script , it says that this disk is 100% full....but before it was doing this total space was 80GB and I am 100% sure that I still had like 35gb of free space left on that disk/drive . And now when i run "sudo fdisk -l" it says
/dev/sda1 * 0 2758655 1379328 17 Hidden HPFS/NTFS
Now this is the first time I have seen this and i have ran that same command before and it would only list /dev/loop0 and would have no ther information on it.???
Ok one last thing I can actually browse that drive and look at the files while i am on the live dvd and when I am viewing all the folders like bin,boot;dev and so on...i can scroll to the bottom and find the two "links" one called "VMLINUZ" and the other called "INITRD.IMG. When I look at those properties it says that they are both "Broken" and the "Link to "" is not valid as the '' does not exist"????? I know those are the Kernel but thats about as much as I know . I hope all this info will help and apologize if i ramble , just trying to provide as much info as possible. Thanks again and if anything else u need me to provide just say it .

And where did i suggest that nonsense? I suggested you something else but you missed my point. I was trying to tell you to boot into live mode of Mint and then using terminal install boot-repair and then run it to fix problem with MBR.

Yeah , sorry about that I was confused obviously. I will try that option now that I understand what u meant , thanks.If i have any luck I will post.
He's using Mint. That means that he has update-grub. So instead of going through all that, couldn't he simply run update-grub from a live medium? Seems a lot easier than other things suggested in this thread.
Well when I run and try to mkdir and mount it says READONLY fs? I need to know how I can change that "read only" filesystem to read-write I suppose . thanks for the help everyone.

Something is mounting it as read only. If you unmount it and remount it do you have the same issue?

You need to remount: mount -ov remount,rw /mount/point
I forgot about this command, which is essential. So when you end up in that point, do that and then you can change whatever you want to.
[OFF-TOPIC]
Loop usually means mounting a file which contains a filesystem, so not a regular filesystem/partition. For instance, you can create a file partition with dd by directing it to a certain file, then you make a partition out of that file with mkfs and then you can mount it with mount -o loop.
