Virtualbox Virtual Machine blue screen restart

Copy the virtual hard disk of the vbox with XP to another machine and only enter the safe mode. During normal startup, it is always restarted in the login window.

After the security mode is enabled, the blue screen is restarted after the addon of virtualbox is uninstalled.
