Just some some context before i ask my actual question.

I know my mac is older so I have been using a USB to use bootcamp.

I have tried installing Windows 10 using the Bootcamp assistant multiple times. The errors that i get are "Status: Disk Partitioning..." once the bootcamp assistant finishes. So I then create my own FAT32 style partition using disk utility. Also have cleared out time machine so it does not manually backup. Once i start the computer in EFI mode or windows i get through to the formatting of the partition but receive this error: "Windows detected that the EFI system partition was formatted as NTFS. Format the EFI System partition as FAT32 and restart installation". So I have tried that reformatting it.

Now I have given up using the bootcamp assistant and tried moving on to unetbootin. Does anyone know if when using unetbootin you need to use a USB 2.0.

Also it has to be greater than 8gb since the iso file + the windows support software is greater than 8gb total.

If anyone has suggestions or answers they would be greatly appreciated.



  • just to make it clear, you want to install windows on the internal drive, not usb, right? – Magnetic_dud Feb 12 at 19:10
  • yes, i want to be able to run Both MacOS and Windows 10 using dual boot – yuurr Feb 12 at 19:18
  • I'd suggest borrowing a windows computer for a minute and making the installer drive using mediacreationtool.exe – Sam Feb 27 at 5:10
