"No boot device is available" in windows parallels

I manually switched off/on my mac after restart my windows parallels is giving error "No boot device is avaialble". I reinistalled windows but is there any way to recover old data as I have old .pvm or .hdd file. I tried open it with parallels mounter but it says "Parallel mounter is unable to open the virtual disk" ANY IDEAS.

Thanks.

I'd start on the Parallels KB. There are many options in there:
KB Parallels: I am unable to start Windows: troubleshooting Virtual Machine start issues

If none of those work I'd contact their support direct.

But before you do anything I'd make a copy of the VM so that you have a backup should the troubleshooting not work and change things for the worse
