The short story is I received a BSOD from a Windows program. I then couldn't boot Windows. My system is set up with GRUB to dual boot into CentOS, so I booted into CentOS and attempted to fix the MBR using TestDisk. Now I cannot boot into either OS, nor do I see GRUB. I am able to view files using TestDisk from a LiveCD so I can see they are still there. Below is the output from a bootinfoscript and a fdisk -l, running from Fedora LiveCD.

Currently when I boot to the hard drive I get a "Hard Drive Error" prompt, that is all.

sdd is the hard drive that contains the Windows and Linux partitions. It says GRUB is installed but I am not booting to it. I have tried to "Analyse" and a "Deeper Search" using testdisk and I forget the exact error but it could not come up with a table.

The table looks fine though according to the bootinfoscript.

Please, how can I fix this? There must be a way!

edit: I have tried booting the Windows 7 install disk and Repair mode does not see its partition. Additinoally CentOS repair mode does not see its partition.

bootinfoscript:

Have you tried running boot-repair? –  user1301428 Dec 13 '12 at 13:28
    
I have not. I can try this evening. I see it is a Ubuntu utility. If there are any tricks or specific usage for it please let me know. Thanks. –  Mike Dec 13 '12 at 13:33
    
Not really, you can tinker with the settings a bit, but usually the default settings are enough. If you want there is also a live CD available ;) –  user1301428 Dec 13 '12 at 13:35
    
It might be worth trying to boot directly into your Linux partition with Super Grub Disc 2 to see that it isn't corrupted - the bootinfoscript seems to think they are (though I could be reading it wrong). It should auto detect your systems and let you try to get in. Did you change anything recently before this (SATA mode, hardware, new hdd, etc.)? It probably goes without saying, but if you have the ability to back up your goodies, that would probably be wise. –  nerdwaller Dec 13 '12 at 15:59
    
I did try using the Super Grub Disc 2 yesterday. I tried all the options and it would just go to a black screen and do nothing. I have not made any recent changes to hardware. The progam I ran that gave me a BSOD was CPU-Z. It doesn't make sense :-| –  Mike Dec 13 '12 at 17:19

The CentOS livecd can be used to reinstall Grub and fix your MBR. Details on this approach are on the CentOS wiki at http://wiki.centos.org/TipsAndTricks/ReinstallGRUB
