Ubuntu Server 15 not booting

[john492]

Hi;

I had Windows Server 2003 and performed a fresh Ubuntu Server 15 installation.
After installation, Ubuntu server not booting :mad::mad::mad:

I guess there is boot problem conflicting with my old Windows Server.

This is my pastebin:

Any help to start my new Ubuntu??
Thanks
