Expected to happen. Installing Windows is not that simple. You have all the prior install issues from the web so I can't hazard what step you missed. Your post didn't detail how you prepared the laptop for the install and we know Microsoft's installer doesn't do it for us.
There can be other issues such as a failed HDD. Your post, besides omitting the prep detail left out why you are not using the supplied OS.

Okay, this is my first post so hold on tight...
I have a completely wiped Asus n61jq. I boot straight from CD ROM with the windows 8, type in key code, accept terms, click custom settings, then I am at the partitioned hard drive screen ECT. When I try to format, it gives me error code 0x80070057. When I click next it brings me to windows downloading screen but stays on 0 percent downloaded until it takes me to the error screen with the same exact error code.
Can someone help me please I'm stressing so hard!!
Am I missing sata drivers or what? HELP!!!
