When attempting to convert my VM from 3.0 to 4.0 I get the following error: Failed to configure the Boot Camp partition Hard disk. A disk configuration error has occurred. Make sure that you have read/write permissions for the disk. Well, I can see why it failed. My boot camp disk is formatted to NTFS. From a Mac point of view it only has read permissions. Can't set it to read/write. How do I complete the conversion in this case. Seems like Parallels team and beta testers should have run across this at some point in time during the testing.
