Editing Windows Installation (section)

==== Format the USB flash drive ====

<pre>
$ diskutil eraseDisk MS-DOS "WIN10INST" MBR /dev/disk2
</pre>

* `MS-DOS` is the filesystem
* `"WIN10INST"` will be the name of the drive. This can be any arbitrary name.
* `GPT` is the partition type. "GPT" is necessary for PCS that boot in UEFI mode. 
* `/dev/disk2` is the identifier of the USB drive. This identifier could be a different value depending on the Mac.

<p class="alert alert-warning">One guide for creating the installation flash drive recommended using the `GPT` option in place of `MBR` when formatting the drive. Using the `GPT` option caused many errors and ultimately did not create a drive that could be used to successfully install Windows. It would boot, and the Windows installation would start, but the installation would fail at various points with a variety of error messages.</p>

After using the `GPT` option there would be two partition options for booting from the disk. With the `MBR` option, there is only one partition option for booting from the disk.

'''MBR''' stands for Master Boot Record and '''GPT''' stands for GUID Partition Table.
