MacOS X El Capitan bootable USB not working

bootmacosusb

I have created El Capitan mac OS X bootable USB using TransMac and El Capitan dmg from Apple. When I boot the iMac (2011) and holding option key, the USB doesn't show in boot menu.

  1. I have changed the clock to 01010116 but the problem still exist.
  2. I have tried this with other sticks (USB 2 and 3) but no luck.
  3. I have tried formatting USB with GPT (diskpart) but no luck.

Can someone give me a few hints on how to get El Capitan installation start?

Thanks

I have used another mac to create bootable USB. For some reason I couldn't use TransMac on Windows to make it happen.
