I'd be relatively satisfied with an answer with suggested examples of how to set up this complex partition table, with any explanation on what is particular or different about the types of partitions needed and where they go, and maybe some example syntax for the command line utilities as well.Īdding this not to answer my own question, but to help whomever answers, and I hope with even easier instructions. If I knew exactly how to set up and where to place the specific individual platform partitions, then I might be able to use one of them. I am aware of and own the commercial application iPartition, and obiously have access to fdisk and gpt amongst other command line utilities available for use which likely could do the job. I found a nice tutorial for creating a multiboot usb thumbdrive via Linux that will boot OS X on a Mac, and Linux or Windows on PCs or Macs, and obviously, if I already have a Linux virtual machine, I could use YUMI as indicated in the tutorial (and I have seen other, similar tutorials that use a similar utilities to do this from Windows like SARDU and XBOOT), but I am hoping to discover a similar OS X native method or application that accomplishes the same thing. I need to be able to create the image in one step to include multiple bootable OS installers (various multiple versions of OS X/Windows/Linux/Linux based Recovery Platforms), all from a single OS X machine. Type the convert GPT command and press Enter.Įnter the create partition primary command and press Enter to complete the process.I would like to be able to create a disk image (that I can transfer via Disk Utility.app to a large USB storage thumb drive) which is a multiboot installer for provisioning various operating systems from a single USB drive. Type the select disk command with the number assigned for the USB flash drive (for example select disk 4) and press Enter. Type the diskpart command and press Enter.Įnter the list disk command to view all drives connected to your computer and press Enter. Search for Command Prompt, right-click the top result, and select the Run as an administrator option. To create a GPT partition on a removable drive, use these steps:

However, this time, you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions. In this case, you may need to redo the entire process again. If the USB flash drive is not working with TransMac, it could still be a partition problem.

Once you complete the steps, you can now insert the USB flash drive on your Mac computer to install, reinstall, or upgrade the operating system to the latest macOS version, which can be Sierra, Catalina, Big Sur, Monterey, or higher. TransMac creates a macOS USB bootable drive warning. Select dmg macOS file to create a bootable USB drive dmg file with the macOS installation files.

To create a bootable USB drive with macOS, use these steps:ĭownload and install TransMac on Windows 10.

You can use a Windows 10 (or 11), Windows 8.1, or Windows 7 device to quickly create a USB bootable installation media to reinstall macOS Monterey, Big Sur, or Catalina on your Mac. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) are not working when you need them the most, you can use a Windows computer to rescue your Apple device. This is one of the main reasons you should consider making a macOS bootable USB when your device works properly. If the unexpected happens with an Apple computer, you can use a macOS bootable USB with the installation media to repair it. It’s just a matter of time until your computer will refuse to start, which could happen for many reasons, including (and not limited to) file corruption, hardware failure, and buggy update. It does not matter whether you use macOS, Windows 10, or Windows 11.
