REM Perform the following only if you need to shrink a partition to make space for the EFI partition. If you're unsure, you can open diskmgmt.msc the numbers will be the same. REM Choose the appropriate disk number from the list.

I'm using 260 MB in this example as that's what newer drives require, but older drives with smaller sectors only require 100 MB. If your primary drive lacks space, first you'll need to shrink your C: partition (or equivalent). I used this procedure to move both the EFI System Partition and the System Reserved partition. For people like me coming from Google: Yes, it is possible to do this with Windows, without any third-party tools.
