You used to be able to burn InstallESD.dmg in 10.8 and prior, this changed with 10.9. support.apple.comen-usHT201372.

However, the problem differs from the one you linked to since I do not want to run an OS X installation in Windows (running in bootcamp) on a Mac.

Neither do I have a recovery partition available, nor another osx.

I tried using PowerISO, but my Mac doesnt recognize the USB stick afterwards unfortunately.

Just make sure the USB drive is formatted with GPT and not MBR.

If you boot holding the option key down, the startup disk selection screen should appear.

I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac.

Someone had reported that the method for using DISKPART did not work, but I have done this twice and it works remarkably well, and its the only method I could find to create a Mac-Bootable Flash.

Ive been trying to post this to confirm that it works for some time, I just hope it helps someone else, because it is a very easy solution.

When I tried to inject the image, Transmac told me that the drive was write protected.

So basically, the USB drive cannot have any high level formatting, the Windows system should detect the drive as not formatted for this to work, which it will if prepped right with Diskpart.

Not say you didnt get an older version to work, however, just to keep others from wasting their time.

The first thing you have to do is make sure what model you have (the year when your computer has been released) then check on the official apple website to see what is the latest macOS or Mac OS X version available for you computer.

In most of the new mac computer, you can just press cmdr while booting and the mac will automatically download everything you need to install the system, but the oldest does not have this tool.

First of all you have to flash the image on a USB drive, I recommend etcher, that works on everything (Mac, Linux and Windows too) its extremely easy to use and you just need to select the drive and the image and etcher will do everything by itself, plus its free here.

When the USB drive is ready you can plug it in you mac and press alt (option) while booting, you have inserted a firmware password, it will ask you to unlock the firmware by inserting that password, else it will take you to all the bootable drives, including your USB device.

If you see the mac logo with a stop icon over it, it means that you downloaded a too new version that is not supported from your mac, else it will start.

When it start, it wont install, saying that the system cant verify the downloaded image, thats why you have to navigate on the utilities menu on the top bar and open the terminal.

Now you have to choices, change the date time, which can work, but may not.

Then try to install the system, if this does not work again, you can start the installation without verifying the image, but you should really trust the image youre using from being corrupted or modified (just to make sure the download went right, use the SHA-1 code to make the file has been downloaded right).

Just a little thing, make sure to have formatted the disk before proceeding, I would recommend to make a partition that takes the whole disk in mac Journaled format, then if you want you will be able to encrypt the disk (the installer will ask you to do that later), instead, if the disk was encrypted before, you will have to insert the encryption key of the disk to continue the installation process.

Really hope this help, I spent a lot of hours to do this on a really old iMac from 2008.
