My system crashed earlier today and is not working properly.

It's saying no disk found.., and not detecting the os.

I tried doing "fixboot" "fixmbr" using the OS DVD but nothing happened.

The drives contain all the data though, as i can see it using command line.

Since i can access CLI (command line interface) is there a way to add the OS entry manually to grub, etc so that the computer can find the os and load it.

I did everything else, checked the hardware and also reset BIOS settings, but nothing happened.

Please help me out guys.. i don't want to lose my OS :)

System config : Windows 7 OS 4 GB RAM, 1 TB HDD

It's not clear exactly what you want fixed. If you have grub, then you have/had Linux. If you put a Win7 MBR back on the disk you're going to lose access to any existing Linux. Is that what you want? – hotei Sep 6 '10 at 19:31
it's simple, the windows installation got corrupted (c drive) and i cannot boot to windows as the boot info is not available as well.., what i think is.................. I will format it – Dhruv Kumar Sep 6 '10 at 19:43

When I've seen this in the past, I've simply gone into the BIOS, specified "no disk", saved, and rebooted. On reboot, I respecified the disk and the issue resolved itself.
