Problems with new Macbook Air

I bought a new Macbook Air the other day and was hoping to get Windows rolling on it so I could use this in a pinch if it was the only computer I had on me at the time..

Install of both Windows 2003 and Windows 7 Home went fine, but once in and doing updates, strange things starting happening...

First I had tried 2003 and I was getting service startup errors (lssas.exe couldn't start) then eventually BSOD's

Then I tried Windows 7 Home (64-bit) and when anything Windows Explorer related was attempted I would get "Device not supported"

Is there anything I missed to try this out? I downloaded Parallels right off the website today, so I know I have the latest and greatest
