What is a good estimate for the size of the BootCamp partition for Windows 10 creators version?
Ideally I'd like maximum size allocated to Mac OS Sierra and minimum size for Windows.
I will use separate external drives for both Mac and Windows to store user files.
MacBook Pro 13" 2017 with 250 GB drive & 8 GB RAM
From How to install Windows on your Mac with Boot Camp - Apple Support,
At least 55GB of free disk space on your startup drive
The partition size can be 55GB or more. The larger, the better.
Hi Gary ...
Best to read the Boot Camp manual before proceeding > Use Windows 10 on your Mac with Boot Camp - Apple Support
Unless Iv missed it there is no information on calculating the partition size any where in Apples resources, this is all there is:
Format your Windows partition
When you complete the assistant, your Mac restarts to the Windows installer. When you're asked where you want to install Windows, select the BOOTCAMP partition, then click Format.
