Delete Windows Partition

[iceman45575]

Hello everyone,

A while ago I had Windows installed on my Mac. I thought I had deleted the partition but now I am running into some problems when I'm trying to install Ubuntu. For some reason when I try booting from my Flash Drive my Macintosh HD and USB show up but also Windows. When I click on it it just brings me to the BSOD with a sad face. When I go to disk utility I don't see anything relating to Windows but I do see a strange thing under my Macintosh HD that says 2 non mounted drives taking up 16GB. I can't find a way to delete these and have Windows fully removed. Any help is appreciated.

Thanks!

The indication of 2 not mounted is probably the EFI and Recovery Partitions which are not mounted. 16GB does not high for those 2 partitions. Select the top device APPLE SSD AP0256 and press the Partition button. Post a picture of the the info shown.

Use diskutil list to show partitions.
Use sudo diskutil mount EFI to mount the EFI partition of the first disk.
Use open /Volumes/EFI* to open all the EFI partitions in the Finder.
In the Finder, look in the EFI folder of the EFI partition. Is there a Boot folder or a Microsoft folder?

Yes there is. I should delete it right?

Is the /Volumes/EFI/EFI/BOOT/BootX64.efi file the exact same size in bytes as the /Volumes/EFI/Microsoft/Boot/bootmgfw.efi or bootmgr.efi file? If so, then delete /Volumes/EFI/EFI/BOOT/BootX64.efi (it is the Windows boot loader that is being shown to you - it is a copy of bootmgfw.efi which uses the files in the Microsoft folder for the Windows boot loader UI and blue screen).

Actually, you should probably just delete /Volumes/EFI/EFI/BOOT and /Volumes/EFI/Microsoft since you're only booting macOS which doesn't require those. Maybe back them up to your user folder just in case.
