When trying to unmount the ubuntu iso after installation and reboot of the VM (during the eject and press enter phase) it doesn't work and fails silently, as in the unmount option remain lit (devices->Unmount CD/DVD-ROM).

To unmount the image i have to completely shut down the VM and unmount from the settings (sometimes it unmounts alone though).

I think that it is impossible if the guest has the cd mounted. So first do an unmount/eject in the guest before you try to unmount it from VB.

Yes although i wish it would allow even if its mounted (simulated cd eject?).

Its kinda problematic when installing a system since you cant unmount the cd your installing with and it wont allow to unmount it without a full shutdown. (even during the eject the cd and press enter phase).

Well my workaround is to directly set boot order to hardisk first
Then start the new machine and directly press f12
now you are in vb:s boot menu press c to boot from cd.
Then it doesn't matter if the cd is left in or not.
