HI all, I have Vista running in a VM on build 1922, Mac Pro/4GB. After a power outage during a bad storm where the power flickered on and off, it looks like my VM is hosed. Now, when I launch it, it stops at the memory POST and doesn't even load Vista. I have performed a full hardware diagnostic, and checked my HD for errors, and there are no problems.
I guess that since you are asking that question, you don't have a backup of your VM. I'd suggest that when you finish rebuilding the VM from scratch, which you may have to do, that you make a backup. The hardware and disk checks indicate that your physical hardware is OK, but the .hdd file holding your VM disk may have been damaged. You might try creating a new VM and attaching your current .hdd file to see whether it's the .hdd or something else. If that doesn't work, Vista may have a repair capability. If it does, booting from the install may give you access to it. I haven't looked at Vista, but Win2k and XP have repair consoles that may be helpful.
Joe, you're brilliant! The problem was not with Parallels per se at all, but rather that the OS loader got corrupted (which could very well be a Vista bug since I recently upgraded to a newer post-RC1 build and only co-incidental with the storm). I was able to run the 'Startup Repair' option from the Vista installation CD and that did the trick. I will however take your very timely advice and create backups of my VM just in case I encounter a more serious problem in future. WHEW -- if only all computer-related problems were that easy to fix.
