right, no grub prompt

But what is funny (let us say funny, as I had all my data backed-up),
I didn't change nothing on my system, I didn' install grub, and I was
still booting off my CD: I suspect that something happened to the disk
when it was attached to a Windows system and the USB system of Windows
detected it, may not clearly dismounted by M$???

Any idea how to recover the situation?? shall we change the title of thread???
