[Can't Login when installing DSM]

I tried it with the password blank, but that also did not work, it's still in the CLI mode (I still can't post a photo),

 

I did this:

DiskStation login: admin

Password: "blank"

and then I got this again: Login incorrect

[Can't Login when installing DSM]

Hi, I'm totally new with all this.

 

I tried to install XPEnoboot DS3615xs 5.1-5022.2 on my Virtual Box, but now it's asking for a login? I can't find a login anywhere, I tried "admin" for the username and "admin" for the password.

 

It loads it all and at the end is says DiskStation login

 

Please can you guys help me?
