Thanks! This was what thought too when I did a spotlight search.
However I wasn't sure becuae, after uninstalled PW (use the code that I found from other thread), reinstalled, it shows this error message:
The virtual machine being started is going to switch VMX mode on. Parallels Workstation has detected that VMX mode is already activated by another running application. If that application will stop VMX, the virtual machine may behave unpredictably.
Click Ok to start the virtual machine with VMX support, or click Cancel and edit VT-x settings.
Whether I clieck OK or No, it shows me "No boot device available, press Enter to continue".
Question: does the (guest) OS being deleted too when PW uninstall?
According to the error message, it doesn't look the case to me. If so, how do I wipe out the Win XP I installed a week ago?
Thannks!
