Hey all,

Am trying to get windows 7 to work properly on my MBA. Am runnin VB 4.1.4, and am now getting an error in the device manager for 3 devices. They are: Base System Device, Ethernet Controller, Ethernet Controller. The second and third make sense as I assume they're my wired and wireless cards, but I have no idea what the Base System Device is.

Thanks for any help!

Nochor,

I'm running Win 7 on an MBA2011 with VB 4.1.4 but I got there in a roundabout way. I started by installing Win7 via Bootcamp (incidentally a key part of this installation was the downloading and installation of Apple specific Windows drivers) as I thought I'd be running my CPU intensive Windows apps in a dedicated Windows 7 session. This I did for a few weeks quite satisfactorily.

I then installed VB and played around with it (ubuntu, xp). I then found a website that had instructions that enabled me to run Win7 in the Bootcamp partition via VB with OSX as the host or by directly booting into Bootcamp in the normal way. After a couple of weeks of flawless execution and excellent performance under VB I decided that I didn't really need the overhead of Bootcamp so I found another website that enabled me to reconfigure the virtual machine and then delete the Bootcamp partition so that now I only run Win7 under VB.

Apart from one glitch - the previous version of VB didn't suffer from whereby if I quit and save a VM the keyboard can go a bit wacky the next time I'm in the VM so I hit the command key twice and it is all good - everything runs well.

You might not need to go through the same roundabout way to arrive at a similar destination but I'd suggest you look for the Apple Windows drivers which will probably make all the difference. Bootcamp Assistant will allow you to download and save the Windows drivers without creating a new partition. You then might be able to use these drivers somehow in your VB VM but you'll need someone smarter than me to tell you that for sure ... or just give it a try.

Good luck,
Pete.
