Yosemite not showing up in GRUB menu

[F4LL3N]

I have a machine where I installed Yosemite and Ubuntu.

- When I boot normally (from the HD) my computer boots into Ubuntu. If Ihold shift during startup and view the GRUB menu, the choices are Ubuntu or memtest and no Yosemite.

- If I choose to boot from my USB Unibeast, the bootloader is Chimera and the choices in that menu are 'USB' or "Yosemite'. If I choose 'Yosemite' then it boots into the OS without a problem.

Both OSes are installed, so how do I make 'Yosemite' bootable from the GRUB menu?

As much as I know, you can't boot yosemite from grub on PC hardware.

@kenstu

oh ok, then how do I load Chimera which will then load Yosemite from GRUB?
