Installing Dev version problems!

Hello every one i’m new to ERPNext so :bear: with me .

1 ) I have virtual-box(VB) installed and up & running.
2 ) I downloaded ERPNext-Dev.ova.
3 ) I imported the img to VB it’s ok till it boots and asks for [username & password].
4 ) I entered [ Administrator // admin ] it says login incorrect.
