Previously I had a windows 8.0 bootcamp install working fine in parallels but my windows 8.1 upgrade went bad and I had to just wipe out the bootcamp partition. Installed windows 8.1 on a new bootcamp partition. Can boot via bootcamp fine to 8.1 but when I try to create a new parallels virtual machine I don't get the option to use the bootcamp partition. Used the kb and tried to manually create a vm and assign the bootcamp partition using the preferences, get the "missing operating system" error when trying to boot. Tried repairing the drive but that didn't help. Anyone have any ideas how to fix?
