I have just finished built a system. I am using a hard drive with the operating system on it but it won't boot up. I have accessed the BIOS and have seen that all the devices are recognized and seem to be stable. I've checked to see that that hard drive is in its SATA 0 port and have seen that it is first in boot priority and the first boot device. However, after multiple tries and restarts, all I get is balnk screen after the computer prompts me to press F2 to enter BIOS . Is there any possble way for the hard drive to work without re-installing windows.
