Hey,

I currently have a laptop with Windows 8.1 and Ubuntu 14.10 on it, and I have been trying to get 10.10 installed on it as well. The only issue I have come across is getting the USB to show in Grub 2. The odd thing is the USB is not showing in the bios either (but it is showing on the bios of my desktop where I have Windows 8.1 and OSX 10.10 installed, and used the same usb to boot). I plugged in another USB to see if it wouldn't detect any USB's at all, but it seemed to detect my Ubuntu Installer USB via bios.

I tried the following commands to get Grub to detect the USB (I apologize if I look absurd, since I don't know my way completely around grub xP):

Code:
set boot=(hd1,msdos1)   # the partition of the usb
chainloader +1   # this is where the error occurred
boot

The error was "error: invalid EFI file path." Which I know obviously means I'm missing a load of steps (or am on the wrong staircase completely).

I have gotten Mavericks installed on this laptop before, when I never had Linux on it in the first place, so I am determined there is a /quick/ solution. The laptop model is an Asus n550jv.

Thanks for any insight.

For installing OS X from the USB you do not boot with Grub. You use the hot key F* to select the device to boot from and select the USB from the list.
Since this is a laptop you are trying to install on, suggest you post all problems in the laptop forum - http://www.tonymacx86.com/laptops/
 
Yeah, that was the issue, it was not showing up on the bios boot select either, so I tried to dig deeper into grub and see if there was a way that way. And okay, wasn't really sure which forum board my topic fell into, but thanks. I'll dig around more and see what I can find. I have a feeling it's something as simple as forgetting to check something in the USB creation, and I'm just over complicating it.
