Gateway NV56R14u windows 8 wont load pass the gateway logo and if it does it will go to a blue screen and say no bootble device then it will say windows boot manger failed to load

SOURCE: windows does not load after gateway logo

This sounds like you have no operating system on your laptop. I bet someway, just as I did before, you have lost your operating system, and it needs to be reinstalled on your computer.

SOURCE: Gateway MA7 black screen, no bios

Take out the hard drive, take out the dvd drive. If you still don't get any video, try another stick of RAM and if that still doesn't work, then the motherboard is definitely bad at that point.

SOURCE: Will pass bios but then will not load windows

step 1. open up the case and locate your hard drive
step 2. carefully remove the cables and power to the hard drive and remove it
step 3. goto your local office depot, staples, walmart or radio shack and buy a nice new hard drive somewhere around 250 gigs should be plenty for you,
step 4. now that yopu have a nice new hard drive put it in the spot where your old hard drive was in the conputer and plug both cables back into the new hard drive, after this is done put your case back on and start the computer up with your windows cd in the cd rom drive and reinstall windows. :) hope this helps
