Unknown operating system, won't boot

I have an Asus G74S. It was working fine yesterday except for being connected to our usual home wifi yet not getting internet. Our other computer, a Mac, accessed it just fine as usual. When I tried to restart my Asus, it only gave me the option to restart Windows normally, which loops me back to the same menu, or enter System Recovery. I tried the system recovery scan 3 times (it took hours each time), restarted between each, and it just keeps bringing me back to the same menu. Perhaps it's because the screen says that it's an unknown operating system.

 

I can't use a System Restore because the computer says it can't find the operating system and that I need to restart and choose one, though when I restart, it brings me to the same menu and I don't see a way to choose an operating system.

 

I don't have a recovery disk, but I do have 3 Windows backup disks I burned when the computer was new. I was able to get into BIOS and switch the boot order to load the DVD drive first, but it just asks me if I want to load the disk image, which I don't want to do since that'll erase my files and programs.

 

The option to choose a system image doesn't automatically detect anything. I have the option to select some drivers. When I open that menu, I can see that my two hard drive partitions (D and E) have their remaining space and files listed, but C is blank. I can open the contents of that backup disk (I just tried the first one), but I'm not sure there are even drivers on it-- just a lot of .sys files. 

 

Is there anything I can do to fix this without losing my files?

I would remove the hard drive...and connect it as a secondary drive on a different system.

 

I would then try to run the chkdsk /r command on the troublesome partition.  If chkdsk /r reports that it cannot complete (via onscreen error message), please post same.

Thanks for the response. Since I'm unable to do that on my own, I had to leave it at a computer place with the means to check. I'll respond when I find out more info.

Well...you could have used a friend's computer to do that, rather than going to a shop.  Friends, coworkers, acquaintances, strangers...they all have computers these days :).

 

But...it's a step forward, let us know :).

Ultimate Boot CDs are only legal if they are created from existing Windows installation discs - which is not in the case of FalconFour's Ultimate Boot CD. So yes, it is not allowed as well.

I didn't have the actual connectors to do it, but anyway, it turned out that I had two hard drives (one was C, the other had D and E) and the one with the C drive had gone bad so I ended up having it replaced and the data transferred since the price wasn't so bad and I needed it as soon as possible to get any work done. Thanks for trying to help though.

Happy computing :).
