It looks like all the larger format screen displays are greyed out, so I need Guest additions to free them? When I click the device menu, Guest additions line I get “Unable to insert the virtual optical disk C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso into the machine Old Windows.Ĭould not mount the media/drive ‘C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso’ (VERR_PDM_MEDIA_LOCKED). All that works great, put AutoCAD 2000 into the win 98 box, but it opens in a window smaller than my phone screen. Help, I’m trying to get Virtual Box to work, I have a brand new Win 10 pro install on a Lenovo Thinkpad laptop.
