Linux Linux mint internet issues

Just finally managed to install Linux mint dual boot with windows 7. But wired net does not work on Linux but works on Windows. Anybody got any ideas ?
Could it be anything to do with PC name or dhcp reservation.

Hopefully sorted it , deleted assigned IP for windows PC and working

If you need the static IP then you can edit the etc/network/interfaces file and add it there,something like this

Before

auto lo eth0
iface lo inet loopback
iface eth0 inet dynamic

After

auto lo eth0 iface lo inet loopback
iface eth0 inet static
address xxx.xxx.xxx.xxx(enter your ip here)
netmask xxx.xxx.xxx.xxx
gateway xxx.xxx.xxx.xxx(enter gateway ip here,usually the address of the router)
