I assume your hold operating device is Mac OS X and you have installed Ubuntu together the guest operating system.

You are watching: Virtualbox unable to insert the virtual optical disk

There is no must mount the guest additions ISO and install from that if her guest OS is Ubuntu.

Instead, open a terminal and enter the adhering to -

sudo apt-get download virtualbox-guest-utilsThis will install the guest additions and is more or less equivalent to installing via the ISO.

I ran into this problem recently (Sept 2017) trying to download Guest enhancements into Oracle VM VirtualBox Manager version 5.1.28, in a newly-installed VM because that Ubuntu variation 16.04.3. The hold is Win-10. The problem was that the Guest additions CD photo was currently mounted. To settle it:

In the VM Manager under Settings->Storage, under Controller:Right-click top top VBoxGuestAdditions, and also select “Remove Attachment."There will be a check box: click “remove.”Click the “+” symbol next to “Controller," come add new optical drive. Adialog box will open. Select “Leave Empty-> Okay”Open the VM and select Devices->Insert Guest Additions. That shouldinstall now. Strength off the VM (not the VM Manager) and also restart theVM. GuestAdditions have to now it is in working.

For me, the equipment was discovering that you have to add an north optical drive in the virtual device settings! If you try to "help" through pre-loading the VBoxGuestAdditions.iso, it doesn"t work. The faster way on the devices menu "Insert Guest additions CD photo ..." desires to uncover an empty optical journey to use!


I addressed by manually mounting the image (after adding the maker and the ISO according to the Dave Rose"s answer) and running the installer.
