Help! I cannot apply an image from a usb drive

I have a new macbook pro.

We apply images to our company MacBooks by a usb drive.

On this occasion I am unable to apply the image on a brand new macbook (pre bundled 10.10.3) the usual way via disc utlity.

There is no error. It "appears" to apply and takes a few minutes. When it "completes" i reboot and a white circle with a line appears on the middle of the screen.

I have tried:

reformatting the drive both on the macbook and usb pen drive.

re copied the dmg image to the usb pen drive

downloaded os x from recovery over the internet and then tried reapplying the dmg as above

Can anyone offer help?

thanks
