Help on boot trouble

I am new in Vagrant using so
I encoutered an problem during VM boot :

Bringing machine ‘default’ up with ‘virtualbox’ provider…
==> default: Importing base box ‘hashicorp/bionic64’…
==> default: Matching MAC address for NAT networking…
==> default: Checking if box ‘hashicorp/bionic64’ version ‘1.0.282’ is up to date…
==> default: Setting the name of the VM: John
==> default: Clearing any previously set network interfaces…
==> default: Preparing network interfaces based on configuration…
default: Adapter 1: nat
==> default: Forwarding ports…
default: 22 (guest) => 2222 (host) (adapter 1)
==> default: Booting VM…
There was an error while executing VBoxManage, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: [“startvm”, “e80b87ba-eb13-4b1e-9c7f-84aebb67d662”, “–type”, “headless”]

Stderr: VBoxManage: error: The virtual machine ‘John_default_1603279783779_20397_default_1603280432298_78052’ has terminated unexpectedly during startup with exit code 1 (0x1)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component MachineWrap, interface IMachine

So could you help me in solving it (and explain also)
Thanks so much

Hi there,

When the error occurs you can usually find a log file created by VirtualBox in the guest’s file directory. In your example above, the log would generally be found at:

~/VirtualBox VMs/John_default_1603279783779_20397_default_1603280432298_78052/Logs/VBox.log

The contents of that file will usually provide more information about the error that was encountered.
