Installation in Windows

I am a PHP programmer, using xampp in windows.
Recently I need to custom a ERPNext system.

From my understanding, ERPNext dev already include frappe framework,python,marieldb.
So i don’t need to create a ubuntu os in vm, just dl and import dev mode in vm.
Am i correct?

But I did alot try to install erpnext dev mode in virtual box.
Keep delete and import dev mode again and again.
Unfortunately, when I try to access http://localhost:8000 it always give me “Page not found or not sending data”.
I try to create a new site and new app, and localhost:8000 still give me page not found

Can anybody give some helps

Can you share if you had any exceptions when you installed updated your VM?

Also which VM are you using?
