Okay, well I recieved an HP ENVY 4-1010sa Notebook PC for xmas and Windows 8 Pro with Media Center to install onto it. I did so and the randomly there came a blue screen saying ERROR: CRITICAL_PROCESS_DIED. So I rebooted it, but upon reboot it came up with a black screen with a blinking underscore, so I have tried a hard reset, DIDNT WORK; reflashed BIOS, DIDNT WORK; downloaded repair disk and attempted a refresh( said hard drive was locked), reset (didnt work) auto repair (didnt work, just rebooted into loop), system restore (said OS couldnt be found), so then i tried a fresh re-install and it couldnt find my internal HDD or a recovery partition, or my SSD. I dont have a clue whats wrong and i dont know where else to turn, please will somebody help?
