I’m trying to set up Fedora as a virtual machine on a Windows 8.1 host. I want to attach the physical boot disk to the machine with a vdmk file. But when I try to add the drive, it tells me I have a permissions problem on the file. The file has full rights for System, Admin and user. Anyone know what the problem might be?

Since you already have user added to the permissions the only thing I can think of is changing ownership of the file to the user. It’s an odd quirk I’ve experienced in the past.
Changed owner to user, same result.
Not that I can offer any help, but may I ask what you meant by “I want to attach the physical boot disk to the machine [snip]”?
Sorry, but if you don’t understand what that phrase means, you are unlikely to be able to help…
What I mean is that usually virtual machines have a virtual drive on the host machine’s drive. I want it to be able to access a separate physical drive (in this case, a bootable SSD).
You might need to run VirtualBox from an administrator command prompt. The actual raw disk access likely requires administrator privileges.
Hmm.. this is probably relevent:
[summary, make sure windows doesn’t have the drive marked as read only]

Yes, that may be the problem. I’ll try it, thanks.
That wasn’t the problem. But running as administrator solved it. Now that the disk is installed, I suspect I can run as user in the future.
OK, apparently not. Have to run VB as administrator to see the disks. That’s sort of a pain, unless I can modify the desktop shortcut.
Right click on the shortcut. Click ‘Advanced’. Put a check mark in ‘Run as Administrator’.
Thank you. As you can tell, I hardly ever use Windows. It’s her machine.
