Vagrant Up Error in cmdr

when I run vagrant up in cmder

I get the follow error

The guest machine entered an invalid state while waiting for it to boot. Valid states are 'starting, running'. The machine is in the properly and try again

If the provider you're using has a GUI that comes with it, it is often helpful to open that and watch the machine, since the GUI often has more helpful error messages than Vagrant can retrive. For example, if you're using VirualBox, run 'vagrant up' while the VirtualBox GUI is open."

I checked out my virtual box and when I try to start the Treehouse virtual machine, it gave me the error message say

"failed to install NtCreateSection monitor: e9 bb eb 15 0 0 0 0 f 5 c3 f 1f 44 0 0 (rc=-8)"

what do I do in this case?

should I reinstall virtual box ?


I have reinstailled virtual box and the same issue still occur, I really need some expert help :(

It looks like you may have bumped into a new issue with the latest VirtualBox. I found some cryptic mentions of the issue on their forums that linked back to this thread. It recommends upgrading to the latest beta to resolve the issue, and that they're doing ongoing work to make sure it's fixed.

Sorry for the trouble Shen JIE LIN! Try giving what Alan Johnson said a try and see if that helps. If not, try installing using the Windows instructions.
