Can't boot Yosemite from target drive

[Claysive]

So my setup is: gigabyte z97-ud7 th
intel core i7 4790k
16gb ram
no graphics card atm
1tb segate hdd
500gb western digital hdd
no ssd atm(maybe that's a problem?)

anyways, so I've booted the usb and installed Yosemite on the target drive and loaded that and ran multibeast. So now I restart the computer like it says to do to complete installation. And this time when I click on my drive with Yosemite installed on it, it just shows the apple boot logo for about half a second then goes back to the bootloader. Any known fixes, as I don't want to always have to boot with boot flags.

Update your hardware details under Profile (Upper Right Side Of This Web Site)==> Basic Information Section. Because no one will check all of your posts for identifying your hardware details.

Is the system rebooting or just going back to the boot loader screen?
