How to create a UEFI USB installer?


Recommended Posts

I want to use UEFI OSX booting on my S2600CP2 board. It's currently booting using legacy. I also have no problems creating a legacy USB installer.

I know the board supports UEFI as I can boot Ubuntu (both USB installer and installed Ubuntu into an SSD) using UEFI. Windows also boots on UEFI (shows up as Windows Boot Manager or something like).

I tried these 2 guides when creating the installer:

1. I followed this guide (https://github.com/Pavo-IM/CloverInstall/wiki/Yosemite) when creating a bootable UEFI clover USB installer.

2. Dual CPU.dmg guide from rampagedev


1. When booting the OSX USB installer, there's no UEFI label unlike in Ubuntu. I have no choice but to select the USB stick from the selection and when it tries to boot, all I see is the cursor blinking.

2. The USB stick was formatted using GPT (confirmed with diskutil list)

Any ideas what I could be doing wrong? Thanks a lot!

ps. From what I can remember all SATA ports on the board are configured as AHCI. not sure if this matters.
