bootcampdual-bootmacoswindows
I have had it with macOS.
I use a 2014 MacBook Air.
To use some apps I need, I had to upgrade to the newest macOS, but this slowed the computer down like crazy.
Otherwise, I stay with an older version of OS X (Yosemite) which doesn't lag, but is not supported by many apps.
Right now I just have macOS. I want to get rid of it and use Windows & Ubuntu.
So how do I remove mac OS and dual boot Windows and Ubuntu on this thing?
In the end I did resolve the problem by approaching the same solution as the guy did. Which was going to the website of the manufacturer and download the most recent driver and now it's resolved.
You did a good job removing the Widows related partitions. I assume your Windows 10 was an EFI/GPT install, therefore you probably still have code left in the EFI partition (disk0s1).
To view the contents of this EFI partition you have to mount it. You can do so with the command shown below.
sudo diskutil mount /dev/disk0s1
Below is a what I have in my EFI partition. I do not have any EFI dependent operating systems installed. If you have any folders that are Microsoft related, you can delete them. For example, the folder EFI/Microsoft.
You can also look for the folder EFI/BOOT. The apple firmware will recognize the file bootx64.efi in this folder as the default name for removable operating systems. You can delete this folder.
When finished, unmount the EFI partition with the following command.
diskutil unmount /dev/disk0s1

You can leave Windows as is and replace macOS with Ubuntu. There will be a conflict between the files in the EFI partition for Windows and the files the Ubuntu installer will place in this partition. One way to avoid this conflict would be to create a second EFI partition when installing Ubuntu. After the installation completes, move the Ubuntu boot files to this new EFI partition.
