On searching I was able to find the problem which was to run virtual environment hyper-v should be enabled and some windows like of mine does not support it
Refer to it:
So I propose we should add the following text to the wiki pagr as a note:" It’s impossible to run bahmni using virtualbox and vagrant on certain windows versions ."
You may encounter issues when setting up VirtualBox on Windows and we encourage you to do your Bahmni related FOSS development on Un*x platforms.
Or something along those lines. I would suspect than less than 10% of people around here work routinely with Windows. I think it is realistic (and effective in the context of OpenMRS/Bahmni) to encourage developers to work on Un*x systems.
