Count not mount the media/drive VBoxGuestAdditions.iso (VERRPDMMEDIALOCKED). + When I tried to mount a shared folder from Windows to inside VM using command mount -t vboxsf StageR122 /mnt, then I got the following error: /sbin/mount.vboxsf: mounting failed with the error: No such device. How to troubleshoot.


I have installed an Oracle VirtualBox with CentOS7 on my Windows 10 desktop without much trouble.
I now want to install MySQL (in the VM), for which it seems I need to share files with the host (because that's where my download MySQL install stub resides) and so require Guest Additions.

I have downloaded the additions from the VB site, and the *.iso file appears in 'c:Program FilesOracleVirtualBoxVBoxGuestAdditions.iso'. It also appears in the VBox Manager under 'Storage...[Optical Drive]' but I cannot get it to install.
I've set up a Shared folder in VM Manager. When I run the VM and go to 'Devices > Shared Folders > Shared Folder Settings' I get a long error message telling me that Guest Additions have not been installed. If I select 'Devices > Insert Guest Editions CD image' (as instructed by the error message) I get another error message 'Unable to insert the virtual optical disk...' (presumably because it's already there?). If I look under 'Details' I see 'Could not mount the media/drive 'C:Program FilesOracleVirtualBoxVBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED)'. I end up going around in circles (mounting, un-mounting etc. etc.).

It would seem that for some reason I'm not managing actually to RUN the *.iso file.

I have seen there were questions about this a few years back, but they were with different versions. I've tried the suggestions there but without success. I'd appreciate some help here please. I must be missing some very simple step?
