My DVD-RAM drive lost..!!

Just wrongly install a Nero Incd software my cd-rom already gone from my computer... Open My Computer also din show out my DVD-ram drive..Delete the software already wait an hour also still not finish processing.. Try to check this check that also cannot find it back. Just a week format, though need to bring the computer go format again. Asked some friends they also confuse.. Lucky another friend teach me step by step to find it back. He said It's because the Incd already modify my driver.. Next time better check properly before want to install anything..
