Hi All, I have an iMac 3.06 4Mg RAM 2008 model, running the latest Parallels. It came with Windows XP pre-installed. Today when I tried to run windows XP Professional I get the following: Windows could not start because the following file is missing or corrupt: <Windows root>\system32\ntoskrnl.exe. Please re-install a copy of the above file. When I put the Windows disk in the Apple drive, nothing happens. I cannot get into the disk to re-install the above. Any ideas on what to do? It's not that I love Windows, it's just that I have some Windows only programs that I want to use. I am not particularly computer literate, so any help will have to be fairly idiot proof.
