E_INVALIDARG 0x80070057

Cannot register the DVD image '/usr/share/virtualbox/VBoxGuestAdditions.iso' {b058bc48-c451-4cff-9db0-d01c70e99c28} because a CD/DVD image '/usr/share/virtualbox/VBoxGuestAdditions.iso' with UUID {bb9b13c5-f90f-4589-b212-8b9e01f118f5} already exists.

Solution:

open the .VBOX file with wordpad:

[...]
<DVDImages>
        <Image uuid="{b058bc48-c451-4cff-9db0-d01c70e99c28}"
location="/usr/share/virtualbox/VBoxGuestAdditions.iso"/>
[...]

Delete all entries between <DVDImages> and </DVDImages> lines.

After deleting the contents, your .VBOX file look like below.

<DVDImages>
</DVDImages>

Save and close the file.

That’s it. Now, you can load the virtual machine without any issues.
