If you’re a Mac OS X user the time will come when your computer won’t boot or a problem may arise where you can’t take control of the device, and booting from an OS X installation media will be required. This is why it’s recommended that you make a Mac OS X bootable USB when your Mac is in working conditions.
But if you find yourself on a scenario where your device (iMac, MacBook Pro, Air, Mac Pro or Mini) is not responding and you happen to have a Windows PC, then you can still be able to easily make a USB bootable installation media for your Mac OS X to reinstall the operating system using the Recovery Assistant. Keep in mind that this will also work for Windows users, who are running Mac OS X on a virtual machine and need to upgrade to the latest version. For example, to OS X Yosemite. Things you’ll need: Your broken Mac OS X computer, a trial copy of TransMac, a USB flash drive with at least 16GB of storage, and a copy of OS X (DMG file). Now that you have all the necessary ingredients, you’re ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps below. How to make a Mac OS X bootable USB installation media 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’ll need to use the Diskpart command-line utility on Windows.
Click Install Now. Accept the license terms and click Next. Select Custom install. Select the partition you just created, which may be marked as 'unallocated space.' Windows will take a few minutes to copy files. After a few minutes, the system will restart and display a boot menu. Select Windows Technical Preview. Dual Boot How to dual-boot Windows 10 alongside an Insider Preview build. Before you can install the Windows 10 Insider Preview build on your computer.
Open Command Prompt with administrative permissions. Type the diskpart command and press Enter. Type the list disk command to view a listing of drives connected to your computer and press Enter. Type the select disk command followed the number assigned for the USB flash drive (e.g., select disk 4), and press Enter. Type the clean command and press Enter. Type the convert GPT command and press Enter. Type the create partition primary command and press Enter to complete the task.
After converting 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., which is the software that will make everything happen. TransMac is a paid software, but it has a 15-day trial solution, that give 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.).
Insert the USB drive that you’ll 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. Right-click the TransMac software icon and Run as administrator.
You’ll be prompted to Enter Key or Run, because we’ll be using it once, click Run. On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive you’re intending to use to reinstall Apple’s OS X and click Restore with Disk Image. In the warning dialog box, click Yes. Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click OK to create a bootable USB of the operating system.
Now, you’ll have to wait a long time. It could take one or two hours to complete the process depending on your computer and other variables. Since you're here.I've got a small favor to ask. This is an independent site, and it takes a lot of time and hard work to produce content.

Isn’t the only free operating system you can install on your computer. Linux can run from without modifying your existing system, but you’ll want to install it on your PC if you plan on using it regularly. Installing a Linux distribution alongside Windows as a “dual boot” system will give you a choice of either operating system each time you start your PC. It’s the ideal way for most people to install Linux, as you can always get back to a full Windows system with a reboot.

Always install Linux after Windows If you do want to dual-boot, the most important time-honored piece of advice is to install Linux on your system after Windows is already installed. So, if you have an empty hard drive, install Windows first, then Linux. If you already have Windows installed, you’re clear to install Linux. When you install Linux after Windows, the Linux installer knows how to deal with Windows, resize its partition, and set up a boot loader with an option allowing you to choose Windows at boot time. The bootloader shows both Linux and Windows options on a dual-boot system. When you install Windows after Linux, Windows ignores Linux, doesn’t know how to resize its partitions, and overwrites the Linux boot loader with its own. You’ll have to repair the Linux system’s boot loader before you can boot back into your Linux system again.
The Ubuntu wiki has, if you need to. You can always just reinstall Linux, too. But it’s best just to install Linux after Windows.
How to set up a dual boot system The dual-boot installation process is fairly simple with a modern Linux distribution. It’s just like installing a Linux distribution normally—you should see an easy option to select. Download it and create USB installation media or burn it to a DVD. Boot it on a PC already running Windows—you may need to on a Windows 8 or Windows 10 computer. Launch the installer, and follow the instructions.
Be sure to choose the option that installs the Linux system alongside Windows, or choose the manual partitioning option and create Linux partitions alongside the Windows ones if you’re comfortable with that. Do not choose the option that will overwrite your Windows system with the Linux one. For example, offers an “Install Ubuntu alongside Windows” option that will handle this for you. You will have to choose how much space to reserve for your Linux system. Typically, you’ll be resizing your Windows partition to make room for Linux, and any room you allocate to Linux will be taken away from Windows. It’s up to you how much space you want for Windows and Linux—if you’re just using Linux to fiddle around, you may not need a massive amount of space. If you plan on installing a lot of Steam games or otherwise using it as your main system, you may want a lot more space.
At this point, Linux installers should be fairly mature and capable of resizing Windows NTFS partitions without breaking anything. But it’s essential to always have in case anything bad happens.
Of course, the Linux installer will only be able to resize your Windows partition to make room if the Windows partition has a decent amount of free space on it. If you have a PC with multiple hard drives, you could also just leave Windows installed on one hard drive and install Linux on another separate hard drive. But they’re perfectly capable of living alongside each other on separate partitions on the same hard drive. Choosing your operating system and sharing files Switching back and forth between operating systems is simple. Just reboot your computer and you’ll see a boot menu.
Use the arrow keys and the Enter key to select either Windows or your Linux system. This will appear every time you boot your computer, although most Linux distributions will boot a default entry after about ten seconds if you don’t press any keys. If you have a modern computer with, switching back and forth between Linux and Windows should be quick. Linux gives you easy access to your Windows files, and you should see your Windows partition appear in your Linux desktop’s file manager so you can easily browse and access your Windows files. Windows doesn’t provide easy access to Linux file systems. Most Linux distributions use the ext4 file system, so you’ll need a third-party utility that supports ext4 file systems on Windows if you want to access your Linux file system from Windows.
A dual-boot configuration is also essential for PC gamers who want to run Linux. Whenever you encounter a game that only supports Windows, you can just —no tweaking necessary.
