GRUB Error 17 & 15?!

Wake up this morning, fire up my computer so i can listen to skrillex, and other musicians, but I am greeted with GRUB error 17 and so i figure oh its my portable... Nope, restart and I get Error 15. So I do what I would do, grab windows install disk and I'm gonna try to restore the Partition table from within the Install disk... Glad I have this laptop...
