To help you out, I need more information:
- By any chance are you running on 32-bit machine?
- Check this to how to enable BIOS on your machine, I googled these out for you. If these don’t work, just google it and I am sure you will find the right way to set BIOS settings:
Use the f12 key, security, virtualization to make sure that it is enabled. If it doesn’t say VT-x that is ok, it should say VT-d or the like.
When your PC is just starting up you should press DEL (or something) to get to the BIOS settings. There you’ll find an option to enable VT-technology (or something).
Also, look at the errors in detail using debug mode while doing vagrant up:
vagrant up --debug
Check for the main error here. If you need help, then share it with me.
