The issue is fat32 only supports files that are up to 4GB in size.
Recent windows ISOs have a file that is >4GB, so you can't have the partition formatted as f32.
exfat isn't compatible with uefi.
- cmurf 6y agoYeah, Win10_20H2_English_x64.iso is UDF these days, which doesn't have the ISO 9660 file size limitation of ~4GiB. Basically same as FAT32. These are the two largest files in that image. 5.0G ./sources/install.wim 534M ./sources/boot.wim I wonder how Microsoft's media creation tool deals with this...
- zlynx 6y agoYou can do it by hand with the dism tool like so, Dism /Split-Image /ImageFile:C:\folder_name\sources\install.wim /SWMFile:C:\folder_name\sources\install.swm /FileSize:3800 I copied that from a ZDnet article with more details. Wasn't sure about posting the URL but searching will find it.
- cmurf 6y agoThe esd file that the media creation tool downloads and then immediately deletes after creating the USB stick, has a smaller version of this file. 4.0G ./sources/install.esd 381M ./sources/boot.wim
- moondev 6y agoYou are right about exfat, what about NTFS? I suppose that's the issue though with macos diskutility no supporting NTFS out of the box. Honestly the other suggestion to use ventoy is probably the best option. Such a great utility
- ccmcarey 6y agoAs far as I know motherboard manufacturers have the option of implementing NTFS support in their UEFI, but it's nowhere near ubiquitous.
