Hello I am using Mojave OS and am trying to install a windows partition but when I try to create a Dos FAT usb drive I cannot change any setting to make a MBR as there is no option for it in the drop down menu.
Also if I create the MS-Dos (fat) usb drive then try to partition it I cannot change from GUID as again there is no option for MBR.
Assuming disk2 is the USB, run
diskutil eraseDisk fat32 WININSTAL MBR disk2
Assuming disk2 is the USB, run
diskutil eraseDisk fat32 WININSTAL MBR disk2
You cannot select MBR in Format list. Exit the format drop down, and click on the Scheme which says GUID Partition Map. What are the available values in the scheme. We can also format it in Terminal, if you post the output of
diskutil list
Also, see Partition a physical disk using Disk Utility on Mac - Apple Support and the section under Erase and repartition a device - Step 4.
You are in the 'Partition' screen. Please click on 'Erase' and check.
Can you also post the output of
diskutil list
with the USB connected to the Mac?
Brilliant I think that has worked.
Excellent. Can you post the output of
diskutil list
for validation?
Is it unusual that there is not an option to erase and include a FAT32 with MBR in the Mojave Disk utility GUI version?
It should not be missing. Are you on Mojave 10.14.2?
I understand this but there is no option (as explained above) to select MBR
There is no list when I click on the GUID theres no list and its not changeable
Hello
The first picture I posted was in the Erase menu and there is no MBR option
What is the command to format the stick (above details) on the terminal command line using a fat32 with MBR? Thanks

Yes 10.14.2
Your disk is correctly formatted. Please continue.
I will check Mojave and post back.
The 'scheme' should be MBR not GUID.
