Can't find /proc/cpuinfo

Hello

When I try to power on a recent configuation there's a message box : Can't find /proc/cpuinfo

There 's no where in my directory a file or a directory with that name. How did it was removed ?

I have another problem : with 4,3G aviable on my disk, il's impossible to make a win98 or better configuration :-/

I'm going mad, so If someone has the answer it would be cool ^_^

Thank you
