System does not boot after being hibernated

Hi all,

I had windows 7 (32-bit) on my Toshiba laptop and I installed Ubuntu 10.04. Both OSs were working fine until I put the system on hibernate in Linux and it doesn't boot anymore. I receive a message like this:

error: no such device: f5353891-...
grub rescue>

I have tried the follwoing but the problem still exists:

- I removed the RAM and re-inserted it
- I can use the original Linux cd to boot and I can see my files but don't know how to fix the problem from inside Linux
- I tried a Windows 7 bootable fix disk and no error was found
- Seems that grub is not installed because I had Windows, so I tried to install it but I don't have access to internet on my laptop

Could you help me with this?

Thanks,
Ali
