I cannot normal start my virtual machine on VB

[Dang Le Trung Nguyen]

Dear all,

I have trouble starting my Ubuntu_17 normally. This announces an error:

Failed to open a session for the virtual machine Ubuntu_17.

The virtual machine 'Ubuntu_17' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\Mr Nguyen\VirtualBox VMs\Ubuntu_17\Logs\VBoxHardening.log'.

Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

Anyone can help me solve this problem? Thank you!
