[Solved] macOS Sierra won't boot without USB

Hello everybody, this is my first time with Hackintosh. I have read some guides and posts about how to install macOS on PC and now I tried to do it.

At first I want to add that I have used this tutorial: https://www.tonymacx86.com/threads/...ierra-on-any-supported-intel-based-pc.200564/

My specification:

Motherboard: ASRock P67 Pro 3 - BIOS 3.20
CPU: i5-2500k
DISK: SSD 120GB
GPU: HD 7870

Everything went smooth till time I wanted to boot installed OS from DISK.
After installation I have installed Multibeast on disk where is installed OS but I can't boot it.

I can easly boot it from clover using USB but not from disk.

Do anyone had similar problem or have working hackintosh with the same motherboard?

## EDIT

I have already fixed this issue. I just installed Multibeast in Legacy mode and now system is booting automatically from disk.

I had a similar problem like this with MAC high sierra but my motherboard was asrock z97m-itx/ac. My issue was there is no UEFI boot option to pick from BIOS once I remove my USB. I followed chibabah's post #3 on https://www.tonymacx86.com/threads/solved-uefi-clover-boot-option-gone-after-bios-update.211715/ thread and was able sucessfully boot without USBhttps://www.tonymacx86.com/members/chibabah.1763246/
