Some small questions about virtual machines

I just learned linux for a short time. The two virtual machine systems created with virtualBox have been installed. The first one can run without any problem, but why can't the second one enter the system normally after installing the system? The status of the second machine is as shown below) Mirror Cenos6.8, is there a god to help my brother solve it, thank you!
(The configuration of the two machines is the same, and the two network cards are set. I am afraid that my own machine has insufficient memory and can't carry it, so the memory is set to 1g)
This is the problem. When the machine is turned on, it cannot enter the main interface.
