Debian 9 is not supported by Converter, so it is expected to fail.
A few notes on the article mentioned:
- it describes a way to do manual reconfig, which is basically correct.
- it omits to mention that you should also call mkinitramfs after grub2-install. You should ensure that the new inirtd image supports disk and network controllers suitable for VMware virtual hardware.
- it recommends altering fstab by replacing with the new volume UUID. This is also fine, though Converter uses block device mounts.
- it blames grub version. In that case Converter recognizes the correct grub version but fails to install grub due to the source machine having kernel 4.19 (Converter helper has a kernel that is too old for that).
In addition you may also use these posts as reference for manual reconfig:
