Windows XP Boots to a blank screen

I have to wonder why a disk imaging and backup application would have over-written the MBR. Since the MBR is on the XP partition perhaps a simple System Restore would have restored that, but I confess I don't know.

The other strange thing is that you 'closed down' the computer, came back to it later and found it was in sleep or standby mode. I don't understand that either.

It is all strange,

But where are you with this now?

Do both XP and Ubuntu boot up?

Does Avira anti-virus and Zonealarm firewall work well together without causing issues?

Are you still using Keriver 1-Click? If so, have you tried reinstalling from that image? What I mean is, you have an image backup, but if you ever need to use it, are you sure it works?

At the end of the day if the whole system works with no issues then I would put this down to a "Windows thing". We see those often here.
