In this tutorial learn how to make a bootable USB flash drive Windows 10 on Mac OS X to install the system either in Boot Camp (i.e. in a separate partition on the Mac) or on a normal PC or laptop. The entries boot stick Windows in OS X not so much (unlike Windows systems), but those that there are, in principle, sufficient to perform the task.
Why this is useful? For example, you have Mac and PC that can not boot and had to reinstall the OS or use the created bootable USB flash drive as. Well, actually, to install Windows 10 on a Mac. How to create such a drive on a PC are available here: .
Recording a bootable USB using Boot Camp Assistant
In Mac OS X has a built-in utility to create a bootable flash drive with Windows and install the system in a separate partition on the hard disk or SSD of the computer with the subsequent possibility of choosing Windows or OS X at startup.
However, a bootable USB stick with Windows 10, designed successfully works not only for this purpose, but to install the OS on traditional PCs and laptops, and boot from it in Legacy mode (BIOS) and UEFI — in both cases everything goes smoothly.
Connect a USB storage device with minimum capacity of 8 GB to your Macbook or iMac (and possibly the Mac Pro, added dreamily author). Then start typing «Boot Camp» in Spotlight search, or start «Boot Camp Assistant» from the «Programs» — «Utilities».
In Boot Camp assistant, select «Create the setup disk of Windows 7 or later». Unfortunately, uncheck «Download the latest Windows support software from Apple» (it will be loaded from the Internet and takes a lot) will not work even if the flash you need to install on your PC and it is not necessary. Click «Continue».
On the next screen, specify the path to the ISO image of Windows 10. If you don’t have one, the easiest way to download the original image of the system is described in the instruction(to download from Mac completely fits the second method, using Microsoft Techbench). Also select the connected USB flash drive to record. Click «Continue».
Just need to wait for when it will be finished copying files to the drive, and download and install the software from Apple on the same USB (in a process can request and confirm the user password is OS X). Once finished, you can use a bootable USB flash drive with Windows 10 almost on any computer. Also you will be shown instructions on how to boot from this drive on a Mac (hold Option go Alt when you restart).
UEFI bootable flash drive with Windows 10 on Mac OS X
There is another simple way to write the installation flash drive with Windows 10 on your Mac, though this drive will only fit for download and installation on PCs and laptops with UEFI support (and enabled booting in EFI mode). However, this may almost all modern devices released in the last 3 years.
To record this way, as in the previous case, we need the drive and the ISO image mounted in OS X (click on the image file twice and it will mount the guest additions automatically).
The flash drive need to format in FAT32. To do this, run the Disk utility (use Spotlight search or using Utility Programs).
In disk utility select on the left the flash drive connected, and then click Erase. As formatting options, use MS-DOS (FAT) and partition scheme Master Boot Record (and the name better ask in Latin, not in Russian). Click «Erase».
The last step is to simply copy all the contents of the mounted image with Windows 10 on a flash drive. But there is one caveat: if you use Finder for this, many error occurs when copying a file nlscoremig.dll and terminaservices-gateway-package-replacement.man with error code 36. You can solve the problem by copying these files one by one, but there is a way and easier is to use the OS X Terminal (run it as he had launched the previous utilities).
In the terminal enter the command cp-R putter/ putlet and press Enter. Not to write and not to guess these ways, you can write only the first part of the command in the terminal (cp-R and a space at the end), then drag to the terminal window first installation disk of Windows 10 (the desktop background), adding to a substantial part of the way automatically a slash «/» and a space (optional), and then the stick (here no need).
Any a progress bar appears, just need to wait until all the files will be overwritten on a flash drive (this may take up to 20-30 minutes on slow USB drives) without closing the Terminal, yet again you are not prompted to enter commands.
Upon completion you will get the installation USB drive with Windows 10 (the folder structure that should be shown in the screenshot above) from which you can either install the OS or use system restore on computers with UEFI.
