16.04 LTS is supported until April 2020 (maintenance), so it's recommended to use 18.04 LTS (18.10 not being LTS and short in support, see : https://ubuntu.com/about/release-cycle ).
This bug does not apply to fresh installs (although it may be related) while wiping the disk, see initial post.
Make sure to check your BIOS settings (EFI/non-EFI, boot sector protection) and please post a new full bug report with full details if you have issues ( I suggest on 18.04 LTS).
Thank you.
