Now that you have all the necessary ingredients, you\u2019re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below.<\/p>\n\n\n\n
How to create Mac OS X bootable USB installation media<\/h3>\n\n\n\n
Before you can use TransMac, you may first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you\u2019ll need to use the Diskpart command-line utility on Windows.<\/p>\n\n\n\n
Setting up GPT partition<\/h3>\n\n\n\n
Use these steps to set up a USB drive with a GPT partition:<\/p>\n\n\n\n
After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.<\/p>\n\n\n\n

Use these steps to create a bootable media to install Mac OS X:<\/p>\n\n\n\n
- Download and install a copy of TransMac<\/strong><\/a>.Quick note:<\/strong> TransMac is a paid software, but it has a 15-day trial solution, that gives us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)<\/li>
- Download OS X El Capitan<\/a> from Apple official website if you do not have a valid DMG file. For more about OS X El Capitan, please see https:\/\/support.apple.com\/en-us\/HT206886<\/a><\/li>
- Insert the USB drive that you\u2019ll use to fix your installation of OS X. (Remember that all the data in the USB will be erased. Make sure you take off any important documents.)<\/li>
- Right-click the TransMac<\/strong> software icon and Run as administrator<\/strong>. (You\u2019ll be prompted to Enter Key<\/em> or Run<\/em>, because we\u2019ll be using it once, click the Run <\/strong>option.)<\/li>
- On the left pane, you\u2019ll see all the Windows PC drives listed, right-click the USB drive that you\u2019re intending to use to reinstall Apple\u2019s OS X and select the Restore with Disk Image <\/strong>option.

<\/li>- Use the Restore Disk Image to Drive<\/em> dialogue box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system.

Now, you\u2019ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.![\"TransMac](\"https:\/\/i3g4v6w8.stackpathcdn.com\/wp-content\/uploads\/2014\/12\/transmac-macosx-to-usb_small.jpg\")
<\/li><\/ol>\n\n\n\nOnce your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option<\/strong> key, and select the USB you just created to reinstall Mac OS X.<\/p>\n\n\n\n
