Bootable usb stick created in windows won`t show in startup manager in mac My MacBook Pro (Early 2015) won't boot any more;  it boots into a flashing screen with a folder with question mark.

I downloaded a High Sierra DMG and created a bootable USB using both Transmac and PowerISO (in Windows 10) and none of them boots the system.

What should I do? Am i doing something wrong here?

EDIT:
I have tried from a ubuntu using dmg2img and then making a bootable stick by dd and it didn`t work either.
I haven't heard of any possible way to create a bootable USB drive on Windows, but if you have access to a Mac you can use Install Disk Creator to easily create the boot device.


Download Install Disk Creator
Download MacOS High Sierra from App Store
