I have a rescued 2013 MacBook Air with a broken screen backlight due to a beverage spill and missing its internal SSD. I don't yet have any OS installed on it. I have access only to (32 bit) Windows PCs otherwise.
I believe there are bootable live USBs these days like we used to use live CDs back in the day. For a Mac live USB stick I'm not sure what partitioning / formatting / filesystem is needed for it to be bootable by Mac firmware. Thus I'm not sure if or how I can create one using a Windows box.
Existing questions that I originally thought were identical are about creating a USB key from an Intel machine running Linux. I currently don't have Linux on any of my Intel machines, all are running only Windows. Thus it appears mine is a novel question here.
