I am using Parallels 5.0.9344 with a Mac Pro (OS X 10.6.3). Every time I am starting Parallels (only after q complete new start of the Mac) I am getting an error, that the Boot Camp partition is missing â€“ Parallels is not starting. I can solve the problem in the configuration, but next time I start my Mac, itâ€™s the same error again! In the configuration, in the harddisk section, there are two harddisks to choose from, one obliviously being the system disk (OSX, because of the size) and the other, smaller one being the second partition on the disk, the Boot Camp partition. I can switch in the source section to the right, Boot Camp, partition â€“ next time same problem, switch to the wrong, system disk again! I tried deleting the whole harddisk section and only attached the Boot Camp partition- next startup same error and switched again to the OS X system disk. I tried closing the little lock in the left corner, after switching to the right partition â€“ next system start, same error! Thanks in advance for any help.
