Bootcamp Slow load time

This is 100% incorrect.

The SSD in your MacBook Air will make any disk reading intensive operation, like booting, much faster on the Air than your MacBook Pro with its mechanical hard drive.

 

I don't know. I am not at all familiar with Windows. I don't know the screen you are talking about.

 

I've had this issue before. It may be due to a missing network drive that windows keeps searching for. I've had this happen when I run my bootcamp drive in virtualization through vmware fusion. Open up "my computer" in win7 and see if there are any drives that have an "x" through them or the icon appears grey (as if they drive is disconnected but win7 is still trying to load it). These drives make the login screen hang. See if you have those drives in your "my computer." Then right click on the drive and unmount or eject it. Alternatively, just right click on "my computer" and select "disconnect network drive." Then disconnect any drives listed in the window that opens. Now try restarting bootcamp to see if that speeds up the welcome screen. Otherwise, you may have installed a bunch of programs that run at startup and are causing the welcome screen to display longer than it usually should.

 

Well, I think it is safe to assume that if you are booting up on the bootcamp side and you have a black screen with cursor blinking for more than 25 seconds, we know why.
Windows security is a b!tch to bypass, which is why most of those illegal copies out there take an unusually long time to boot.

 

Ahhh gotcha. The DOS cursor is a dead give away for illegal copies. Mouse cursor sounds like a driver issue.
I can tell you this though (since we have the same computer), I had a hell of a time installing Windows 7 Ultimate 64 bit. Kept giving me issues (similar to what you are describing.) Got fed up with it and went back to 32bit. Never did figure out the issue. Ran out of patience. I simply don't use Windows enough to bother, however, sounds like you def need the 64 bit version.
