Dual Booting Ubuntu Bad Master Boot Record (MBR)
So i two days ago i installed Ubuntu on my Secondary hard drive. I already had windows 7 installed on my primary drive. When i installed Ubuntu i didnt realize it at the time but i installed GRUB over Windows Master boot record on my primary hard drive that has windows installed. GRUB has been working but i wanted to restore my Windows MBR on my primary drive and have GRUB only on my secondary drive, and then if needed i could switch back and forth via the bios. As of right now i have NO Master boot record. At least not a functioning one. I am getting the error : Missing Operating System every time i turn my pc on. I tried using my windows 7 installation disk and repairing my computer, unfortunately when it shows a list of operating systems it isnt showing anything. I can then go and try to load a "device driver" while in System Recovery Options and i can indeed see that my hard drives are not at all formated. I still have windows installed. Also when i run the command prompt from system recovery options i can run fixmbr and other similar commands which say that they recognize windows is installed on a hard disk but having some kind of issue with the drivers for my hard disk. So i tried to FixMBR and then i now think, im not sure, but i would think i need to get the drivers for my Hard disk, or hard drive and install them in system recovery options. But thats where im really stuck, how would i even find something like that out? What can i do?
Btw to recap, i cant use GRUB or windows MBR
I cant even start my pc, unless its from win7 installation disk
Anyway if anyone could help that would be great,
As for my hard disk im not sure what it is, but i know this
I have a Asus G73JH with a 500Gb Sata drive that comes standard. 6gb ddr3 ram and a mobility radeon hd 5870, and an i7 720qm
Thanks all help would be greatly appreciated
