My first guess is, that it's a GRUB issue. What messages appear before this message appears and is waiting for pressing a key? Perhaps only GRUB messages are shown. I suspect that the splash screen does hide upstart messages, so "booting" hasn't started, since no splash screen appeared. Assumed booting should have started, then we should care about log files. However, I googled "malformed file press any key to continue". And my guess, based on the fact that no splash screen appeared, that GRUB might be the culprit, seems to be not that bad.

JFTR GRUB and GRBU2 are known to be poor bootloaders. A lot of experienced *nix users don't use it. I'm using it anyway, but I don't upgrade it. IMO there's no need to upgrade GRUB. There's no drawback and the advantage is, that you won't get a buggy update. </pre> </blockquote> <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
