So In the past I have been using vmware but with some mouse freezing issues i've been looking for an alternative. I'm trying parallels, but I can't for the life of me figure out how to set up the virtual machine? I can't seem to find the vmx vmware config file so I'm just letting it select my boot camp partition (vista already installed) to use...but it sets it up, and then when i try to start up the machine I get this error. "Unable to connect Hard Disk 1. A file or device required for the operation of Hard Disk 1 does not exist or is used by another process, or you have no permission to access it. The virtual machine will continue running, but the device will be disconnected." I don't know how to proceed, please help. EDIT: I found this suggestion (below) online, and while trying to find the config file (couldn't find it) I just double clicked on the vmname.pvm and it mounted it or something and started up. I'll keep it updated if there are any problems. "Found the problem. -Edit /Users/<user>/Documents/Parallels/<VM Name>.pvm/config.pvs -In the <hdd> section, find <SystemName> -Change "/dev/disk0" or a similar value to the full path of the disk image in the same directory. In my case it was "/Users/<USER>/Documents/Parallels/My Boot Camp.pvm/Hitachi HTS############.hdd" -Restart the VM"
