Recently the sata hard drive on my Alienware 14 partly died. It still works in very few ways but takes about an hour to completely get to the desktop. And runs extremely slowly.
I decided I to buy a new SATA, a Western Digital 750 gb hard disc drive 7200 rpm. The only difference between my old hard drive and this one seemed to be it was a SATA 6 gb/s whereas the old one was SATA 3.0 gb/s.
When I got the new hard drive I install it on my own, no problems at all, but when all was done and I turned on the computer I got a message saying:
Intel UNDI, PXE-2.0 (build 083)
Copyright (C) 1997-2000 Intel Corporation

For Bigfoot PCIE Ethernet Controller v2.1.1.1(02/09/12)
PXE-M0F: Exiting Intel PXE ROM.
No Boot Device Found. Press any key to reboot the machine.

Once I press any key it restarts and the same message comes up. After taking it apart and reseating the hard drive several times still no progress.
Please let me know what I should do.
