Hi,

I'm trying to install Windows 7 as guest. So I made a new virtual machine, then I attached the iso image I got from msdnaa to my virtual cd/dvd drive. However, when starting, I got this error: I'm trying to install it on a Mid 2011 13 inch macbook air with this hardware:

• Intel Core i5 @ 1,7 GHz
• 4 GB 1333 MHz DDR3 Memory
• Intel HD Graphics 3000 384 MB
• 256 GB Flash Storage

I'm trying to install Windows 7 Professional with SP1 (x64).

Does anyone have an idea what could be wrong?

Try activating IOAPIC in the guest settings.

That seems to work, at least I'm in the installation now, thanks a lot!!

I have this same problem. I'd like to try the solution offered, but I have no idea how to activate the IOAPIC settings. Can someone help?

It is in the guest settings -> system -> motherboard.

Thank you - this worked perfectly.
