So I have installed Windows 7 on my iMac, despite not having the proper Boot Camp drivers. It did eventually install, however lacking the proper drivers is causing me a few issues.
Notably though I can use the wireless keyboard and mouse to log on to Windows, once logged in, the iMac under Windows 7 decides that it can no longer see the keyboard and mouse. So the only solution is to plug in an USB keyboard and mouse. The thing is that the OS can see the keyboard and mouse, it’s just that they don’t function!
The other problem is with the audio drivers.
Hopefully it won’t be too long before Apple release proper Boot Camp drivers for Windows 7.
