I finally got Lion today and i ran into some trouble when trying to install windows 7 vis vmware and parallels. Where id get an error message: The master boot record (MBR) of this virtual machine's hard disk does not contain valid bootstrap code. It is likely that the MBR was corrupted by an incorrect guest operating system installation or some other reason. The virtual machine cannot continue and will now power off. (For advanced users: the MBR is the last disk sector accessed by the virtual machine before the error.) Please consult our Web site at "http://vmware.com/info?id=18" for common troubleshooting help.
