For those that want to use the auto-install feature, there are a few things you should know first.
Android-x86's bootable USB Auto-Install feature will only work for Android 9 and below. and it requires a MBR or Legacy boot setup and not EFI.
It sets a fixed size for the data image and does not allow for proper root as well. So if you still require the use of Auto Install, please note that we do not support this method as it is outdated.
