I am trying to install Ubuntu 14.04 in HP EliteDesk 800 G2 SFF, in which Windows 7 is also installed. While wired network connection works well on Windows, it doesn't on DVD-booted Ubuntu. Then I noticed that only IPv6 address is set:
$ ifconfig
eth0 Link encap:Ethernet HWaddr 48:0f:cf:41:c7:83
inet6 addr: fe80::4a0f:cfff:fe41:c783/64 Scope:Link

TX packets:49 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:4880 (4.8 KB) TX bytes:4880 (4.8 KB)
I followed this instruction, but still cannot connect to wired network.
$ sudo cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
$ sudo service network-manager start
start: Job is already running: network-maneger
$ sudo /etc/init.d/networking restart
$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 48:0f:cf:41:c7:83

What should I do to connect to the network so that I can move on to the Ubuntu installation?
