Windows 7: Cannot boot my laptop, windows can't find any hardrive to boot OS..

Today when I was surfing on my laptop (G74S Series) I wanted to restart the laptop because the internet crashed and it usually helps to restart. But I restarted it holding down the power button thing.
So, I restarted it and while I was waiting, staring in to the screen, the blinking "_" thing when you start up was doing that for a while and nothing was happening, and a couple of seconds later the computer tells me that it can't boot the laptop/pc because no drive was found. I saw an error code but I didn't catch it, but it was something like "0x0000"
So then on later, it sent me in to "Image Restore" But I have no image to restore with, so I cancel it, and then it sends me into the menu where I can choose to "Restore Computer" or "Scan for startup errors" or something like that (I don't really have a such accurate memory.)
And on the top it also says "os unknown on (unknown) local disk"
Everytime I start the computer it sends me to that menu where I can choose to restore my computer etc..
And I can't really do much about it since I don't have the windows 7 disc/dvd thing either.
And this all came all so sudden I don't really know what to do.
I don't have any backu or anything, and windows can only detect my /D: drive and not /C:, and I have my OS on /C:

Is my hardrive corrupt or what happend?
And what should I do?
Any suggestions?
Hope I posted this on the right part of the forum..

Did you make the OEM manufacturer's Recovery Disks?



You can order OEM Recovery disks from your OEM manufacturer's website.



Check the hard drive with the manufacturer's diagnostic tools.

I never made any backup or any recovery disk, and I don't really know if I can get any tools to help, since I'm in Thailand right now.
I'm going back to Sweden again the 15th and probably leave it in there since I have a Warranty of 2 years.

But is there any other solution?
