HD problems

Last night, I expirenced a serious problem with my computer where it would suddenly not turn on becuase the boot file was not found. After awile, my system would tell me that the NTLDR file was missing. I eventually decided on reinstalling windows, but once the installation was complete I found that only one of my hard drive showed up on the device manager. I tried unplugging/plugging it in while the computer was on so that it could be detected, but nothing happen. Hardware wizard did nothing either. Could my drive possible be dead?

You could have just copied the ntldr file out of the C drive of a different computer.
