I have a MacBook and the OS X on it is not working. It doesn't boot anymore. I want to find out a way to make a Mac bootable USB stick from Windows 8 because I have access to a Windows 8 laptop. How can I develop a USB with support for booting Mac?
What to do for creating a Mac bootable USB drive in Windows?
To make a bootable Mac USB flash drive, you need a USB flash drive that doesn’t contain any data because it’ll going to be formatted. On your Mac PC, connect your USB flash drive to your computer then open Disk Utility. On the list located on the left side, select your USB flash drive that you want to make bootable.
Select Erase tab then format the drive using Mac OS Extended (Journaled). Select Erase and then confirm. After that, go to Partition tab. Under Partition Layout, click on the pull-down menu then change it to “1 Partition” instead of “Current”. Change the name of the partition to “Untitled” instead of “Untitled 1” then click Options. See image.
On the next screen, select GUID Partition Table then click OK. Click Apply then confirm. When the format is finished, close the Disk Utility. See image.
Once the USB flash drive has been formatted, download the Mac OS X installer from the Mac App Store either Mac OS X Mavericks or Mac OS X Yosemite. Once the installer is downloaded, do not install it. Open the terminal then enter the following command:
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X Yosemite.app –nointeraction
When you are prompted, enter your administrator password to continue. Wait until it is finished. When it is complete, you will see “Done” in the terminal. Exit the terminal and your Mac bootable USB flash drive is now ready to use. See image.
