Run the app in compatibility mode Choose Properties, and go to the Compatibility tab. Click on Run compatibility troubleshooter or just check the Run this program in compatibility mode for field. Save your changes, and run the program with admin rights. VirtualBox should now open on your Windows 10 system.
Go to the File menu and activate Environment setting or, in more recent versions, Preferences. Select Display and change the setting for Maximum guest screen size to “hint” which allows you to set an arbitrary size for both width and height (e. g. 1920 and 1200). Reboot the virtual machine and enjoy it.
This happens on our work airgap machine when someone forgets to shut down the virtual machine at the end of their session. Restarting the machine resolves the issue, for me. Show activity on this post. For me with Win 11, giving full control to current user in security tab of .vdi file and then uninstalling and reinstalling VirtualBox, worked.
I did check the obvious - the .vdi file is *not* read only. I've tried starting up virtual box as myself and as administrator, but starting as administrator gives a bunch of other errors - and I installed it as myself. any help would be greatly appreciated!

Virtualbox version: 6.1.16 with extension package, Windows 10 is the host OS and so is the guest, Hardware virtualization is enabled otherwise would not have been able to run a fresh install of windows on vbox - Tried changing my vbox settings to run as admin and the permissions seem to check out.
Right click on Virtualbox ICON and "run as Administrator". Or change the rights of Virtualbox. Hope it helps. Show activity on this post. I have suffered from the same problem recently. I changed the permissions of my visual disk image.Then It works. 1.Right click your .vdi file. 2.Select property item in the popup menu.
Right click on the .vdi file . Click on properties . Just uncheck Read only . And start VirtualBox with administrator priviligies. This done the trick for me . :)
