BIOS is not detecting HDD. showing operating system not found…
Arvind, sounds like you are having a failed hard drive. If you have an external HDD case you could try and see if it is accessible by another computer. You can also set you BIOS to use the optical drive as the first boot device and try to use a bootable CD, (I use Puppy Linux) and see if you can access the drive through that. Right now however, it sounds like you will have to replace your HDD and reinstall your OS and your drivers. Hope this helps, good luck.
