"VirtualBox Guest Additions" Installation error - Unable to insert the virtual optical disk

To copy paste from Virtualbox guest to host & vice versa, I typically follow the steps listed in my earlier blog post - How to - copy/paste from VirtualBox guest to host & viceversa. Though it worked for me many times, I got the following error pop up recently when I clicked on the "Devices" in top bar menu and clicked on "Insert Guest Additions CD image...":

             

In this post, I will provide steps to install the "VirtualBox Guest Additions" in an alternate way.

• Shut down the VM

• I right clicked on my VM in Virtualbox Manager, clicked on the "Settings" displayed menu, selected "Storage" tab, right clicked on "VBoxGuestAdditions" & clicked on "Remove attachment":

             

• Clicked the "+" icon next to "Controller: IDE" to add a new optical drive. Choose "Leave Empty --> Okay":

             

             

• After this, restart the VM & follow the same steps as I mentioned in my earlier blog post - How to - copy/paste from VirtualBox guest to host & viceversa to install "VirtualBox Guest Additions".
