Sounds like you did a UEFI install, then didn't set secure boot in your motherboard settings. I for one, have a dual-boot "amazing" Gigabyte board that has BIOS and EFI. I know I had to turn on the Windows 7/8 features (joy), and for CSM, select "never" and installed again. What is your hardware?
I'm closing this, because this issue hasn't been updated by the OP for a very long time.
Choosing the automated install option, the whole thing goes through seemingly successfully. On first reboot, my machine doesn't find a bootable drive other than my usb stick. It's as if the hard disk isn't bootable after install. The vanilla steamos seems to work OK in this regard.
