Apologies..It seems its high time I get my spectacles
For the problem of OP I am not sure about the distro but I have faced this type of problem with RHEL 6 some times
Where I manually create a eth0 file
Code:
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
and mention the details of Ethernet card
as if the ethernet card is visible in windows then it must be there in linux as well
just check the o/p of lspci as said by other members and if you see Ethernet controller then
try
