i am currently have macbook pro 13 early 2015 with only window 10 installed as an operating system. i want to format the hard drive and install back macOS (go back to factory setting). i have downloaded the mojave.dmg file and follow the instruction how to do bootable usb (16gb) with mojave.dmg file on window. After i done all steps and follow shut down and then open the macbook pro by hold down the alt key. it only shows 2, window boot and EFI boot. why i dont see the Mojave boot to install macOS? how can be fix?

Post the directions you are using. To make a bootable installer you need the Mojave installer app, which should not be contained in a DMG for this to work via the standard terminal method.

I have noticed that sometimes, when I make a bootable USB stick, in Mojave and earlier versions, the first time you boot it up it will show EFI boot. You can click on that and it is what you want. Using it again later, it always corrects itself to show the installer icon. But EFI boot is your installer.

Also worth noting if you ever had 10.12.4 or above installed, your boot rom has been updated such that if you hold down CMD+Option+R you will boot to internet recovery for the latest compatible macOS version. So in your case it will take the machine to the latest Mojave.

The only macbook pro with window 10 installed that having problem right now, is that i have.
Others all window OS. so thats why i need to do the bootable usb through window.

If I’m hearing you correctly, that does not matter. Even if the computer only has windows on it now, using internet recovery will load macOS recovery without the need to use a bootable usb drive.

The Cmd-Opt-R on boot BLUEDOG314 suggests is something you do before Windows loads. It doesn't matter what OS you have, or even if you have a blank drive, or no internal hard drive at all. Cmd-Opt-R will work no matter what.

Shut the system off. Press and release the power button to turn it on, then *immediately* press and hold Cmd-Opt-R (⌘ ⌥ R) until the system starts loading the recovery system.

i never do the internet backup, only usb bootable can work for me. i got what you mean about the short cut key now. i reinstalled the window back and it works with it. i am using it for now and will try to make the macOS majove bootable usb work in the future cos i want to change it back to macOS.

Thank you very much for your help mate :)
