MacBook Air 2015, Mojave installed, 125 GB flashdrive
We had a VM for windows, but with installing Mojave, deleted everything additional down to bare Mac OS and tried to install W10 with boot camp assistant (BCA). According disk utility, MacOS is taking 27 gb (including W10 iso file), free 93 gb. BCA partition keeps 47 gb for Mac, with remark 8 gb free. It will not go lower.
I used Disk Utility to make a disk partition of 30 gb for Mac, 90 gb for second partition. No problem. I deleted that partition, again disk space 120 gb, free 93. Tried again BCA, no dice, will not go below the 47 gb for Mac OS.
Any way to push this lower? I would like to go 85 gb for W10, 35 gb for Mac. That should be enough for both OS and some working space for extra programs, all larger data files go through external drives or cloud.
