While this is correct there is another approach you could use and that is to create the partitions before hand. This is useful if you have some other partitions on you disk you don't want to break.
You can partition your disk using gdisk (I use the Linux version but you can use the Windows one it is exactly the same apart from the initial syntax).
The order is not important but this is the default.
You should start in 40 and you should (if you may use another OS) leave 128MB between partitions - see http://rodsbooks.com/gdisk/advice.html
Make a 450 or 500MB Recovery partition. Format should be NTFS and partition code should be 2700. This one is completely optional.
Make a 100MB or 200MB EFI. Format should be FAT. This is required and the partition code must be EF00
Make a 12MB MSR Should be unformatted and partition code should be 0C01. Microsoft are vague what this is for but as it is tiny and there is a possibility it is required so then why not. Windows does work without it though currently.
Make a <whatever size> C drive. Format should be NTFS and the partition code 0700
Then when you install Windows, pick C partition and it will figure out the rest and not touch any other partition.
Alternatively you can copy the loaders from your ISO into the ESP and copy everything else into your C drive. When you boot Windows will install but you'll have to delete the installation directories after. That is a boring and long winded way of installing but is required for old Apple computers for example.
You can change the GUID after if you have a problem using GDisk.
It should look like this:
Then install Windows (either normally or just copy the contents of the ISO to C drive)
