I built a new computer today. Closed the case, started the system and configured the BIOS:
AHCI is selected.
The boot order is USB > HDD.
I don't have a DVD driver.
Both keyboard and mouse are USB and are working fine while configuring the BIOS.
I inserted the bootable USB, rebooted and the error message "Reboot and select proper boot device" appeared on the screen. I put it in all the different slots (2.0 and 3.0) to no avail. I tested USBs with Ubuntu, Windows 7 and Windows 8.1 (I have original licenses for win7/8), all returning the same error message.
I switched my WD 1TB HD to an old 160GB one with Ubuntu server installed and tried to boot from it — to my surprise, it worked flawlessly. So the problem is apparently with the bootable USBs. I can't boot from them, thus not being able to install an OS.
Lastly, I tried Plop Boot Manager. I can load it and choose to boot from an USB, but it freezes in a black screen.
It has the following configuration. All parts are new. (this is a link to the build in pcpartpicker.com with complete specs)
ASRock 970 Pro3 2.0
Kingston HyperX 8GB
XFX Radeon R9 270
OCZ ModXStream Pro 600W
Thermaltake Commander MS-I
I'm trying to create new bootable USBs (I might try with a 8gb/16gb one, I only used 4GB ones), because I really have no idea what to do next. Any idea? Some BIOS configuration that could be problematic? I'm on Mac OSX, probably going to install Windows via Boot Camp to use the Microsoft program to create bootable USBs.
Thanks for your time!

After that, I installed the drivers from AMD and ASRock and upgraded my system to Windows 8.1. I was dumb—you should install the GPU driver (so the Win8 updater can run under the right resolution) and then install only the Win8 drivers. Anyway, it's working!
