BIO version is F11. when i try to install a guest operating system under windows 2008, it gives error virtual machine connection.. the application encountered an error while attempting to change the state of 'winxp'
'winxp' could not initialize (virtual machine ID AB11x....

configured it for RAID 1.. the error is due to BIOs or OS issue?

What is your main windows operating system, windows 2008 is not the correct name of an OS, so I'm just asking to be sure.   

And what operating system are you trying to install in your virtual machine (Just XP)?

What program are you using for virtual machines, and can you please post the full error you are getting.
