(mod edit: originally posted on old topic: "debian-10.7.0-amd64-DVD-1.iso-VM on VirtualBox 6.1.4 - installation failed")

I've tried the installation with or without active mirrors and my installation still fails. My Hyper-V settings are disabled so I don't think that's the issue. Is there any other solution to this??

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.
