Computer won't boot says Boot Failure press any key to continue?
I have that problem too. 1st check your SATA n' power cable to
HDD, okay? Then go to BIOS n' see if your HDD is being detected,
yes or no? Even after that it does not show your HDD, try to put
that HDD in your friends PC. If it worked then problem with wires.
Replace SATA n' power cable with new one. If even in his computer
it gave error than you have to buy a new HDD.
