By "unformatted" hard drive, I mean exactly what I say: not formatted, blank, NO OS. I ordered it, received it , installed it. After about 2-3 hours of struggling to get the damn machine to even power on, I succeeded at that, but without any video output. Now, in this case, I should be presented with the BIOS screen first, then the Windows installation should start to load. However, IF this IS happening, I can't see it happening. Please help.
