Right-click the guest in the main Virtualbox window's guest 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.

Re: Failed to open a session for the virtual machine boot
Uninstall and Re-Install VirtualBox. The next method to solve the most common method to solve the "Failed to open a session for the virtual machine" problem in VirtualBox, is to uninstall and then to reinstall the VirtualBox application, especially if the problem appeared after a Windows Update.
