VirtualBox breaks down when trying to "add" ISO

Postby router55 » 10. May 2021, 11:10

Hello guys,

I am trying to run a windows virtual machine on my mac.
I have already initilialized a new VM.

When I run the VM, I receive the message to "Please select a virtual optical dsik or...".
So by clicking on the folder icon in the bottom right corner, I want to add a new BIOS, so the VM can load the operating system to boot up.

Yet, when I click on the "Add" Symbol, VirtualBoxVM breaks down and I receive the following error information:
The VM session was aborted.

Error code: NS_ERROR_FAILURE (0x80004005)
Components: SessionMachine
Interface: ISession {c0447716-ff5a-4795-b57a-ecd5fffa18a4}

My mac is up to the latest software and I have tried reinstalling VirtualBox several times.

I would appreciate your help greatly!! I need a VM for my bachelors thesis...

First, make sure you're not using an M1 Mac, see the stickies at the top of Mac Hosts.

Then please see this by "paulmc" viewtopic.php?f=8&t=101717#p494214. Please report if it helps.

Hmm, the cited post by yours truly {from the thread "can't add startup disk on mac osx"} is just a tad longwinded, as happens quite often with me ;-). It might be all-too-easy to miss the redirection in the TL;DR section at the top, and end up slogging through the Detailed section.

Also, one of the quickest — and since confirmed — workarounds I'd listed at the bottom of that post {i.e., "• Try attaching the ISO disc-image fi{l}e via the system's own Open dialog"} actually refers back up into all those details! There's a hopefully clearer description of it in the last sentence of this other post {from the related thread 'Virtualbox 6.1.18 crashes when adding Disk Image (NS_ERROR_FAILURE)'}.
