MS-DOS (FAT32) USB to MS-DOS I am attempting to set up bootcamp for my 2013 MacBook. I have a 16gb USB for the Windows ISO. The USB was formatted in MS-DOS (FAT32). I need just MS-DOS for bootcamp. I attempted to switch it using Disk Utility but when i erase and select MS-DOS it just erases and reverts back to (FAT32)? any way how to fix this?
For all practical purposes MS-DOS is MS-DOS (FAT32) nowadays, see https://www.howtogeek.com/235596/whats-the-difference-between-fat32-exfat-and-ntfs/ for instance:

FAT32 is the oldest of the three file systems available to Windows. It was introduced all the way back in Windows 95 to replace the older FAT16 file system used in MS-DOS and Windows 3.

Limitations come with that age, however. Individual files on a FAT32 drive can’t be over 4 GB in size—that’s the maximum. A FAT32 partition must also be less than 8 TB, which admittedly is less of a limitation unless you’re using super-high-capacity drives.
