Fixing the Screen Size of Windows in VirtualBox The following instructions explain in detail how that is done. Thankfully, it is rather easy to unlock all supported screen resolutions in VirtualBox. The scaling options are unlocked and available, though. The 'resize to' options are all inactive, as they are grayed out and not selectable. The View > Virtual Screen menu of the VirtualBox application lists all available resolutions and scaling options. Otherwise, the VirtualBox warning will show up again.The low resolution may be sufficient for some tasks, but many may benefit from larger resolutions. Don’t forget to remove the virtual DVD from the new VM. If you want to keep the VM that belongs to the snapshot, you first have to create a full clone of the snapshot and then delete the snapshot.

Deleting the linked clone or removing the virtual drive in the corresponding VM doesn’t solve the problem I also had to delete the snapshot.

In my case, the snapshot belonged to a linked clone. You can do this in VirtualBox console by clicking the Snapshot tab of the virtual machine. One way to get rid of the problem is to simply delete the snapshot. The question is, how can you detach a virtual drive from a snapshot? I am unaware of any method that allows you to do this directly in the snapshot. A closer look at the attached information reveals that the ISO file is not just attached to a virtual machine but also to a snapshot. The first solution that comes to mind is to simply remove the disk from the virtual drive. The ISO file is attached to a virtual machine, and VirtualBox therefore disapproves meddling with the file. You can see the reason in the Attached to field of the screenshot above. Thus, I can’t tell Virtual Media Manager the new location of the file or that the file is no longer required. As you can see in the screenshot, all options to manage the ISO file are grayed out. If you deleted the file or want to move the file to a new location, things can get tricky. If you restore the file, the warning will disappear. You’ll see the file name and the original location. In my case, it was a Windows 10 ISO file. The tab with the exclamation mark contains information about the missing file.

This will open the Virtual Media Manager, which you can also access through the VirtualBox File menu. However, these warnings sometimes point to a real problem and it therefore makes sense to click the Check button. VirtualBox Warning - One or more virtual hard disks, CD/DVD or floppy disk image files are not currently accessible.įirst of all, you can, of course, get rid of the prompt by checking Do not show this message again.
