After Installing 7 w/ Boot Camp, can't access Mac Partition

Hold down Alt/Option on the keyboard as the system reboots.

You'll get a boot loader menu.

BootCamp changes the startup disk to the Windows partition to help with the install of Windows but does not change it back.

When you startup hold the option key and then when you get Mac OS up and running go to System Preferences > Startup Disk click on the Mac OSX disc and the quit system preferences (you don't need to restart for the change to take effect......)

That way the default startup is Mac OS and if you want to boot into Windows just hold the alt key and choose Windows.

What if holding down option doesn't work? I keep trying but windows starts up anyways.

I found that my MBP always boots up in the OS I last used before shutting down. When Win7 boots up there is a grey diamond in the task bar on the RH side. Click on this and you will be asked if you wish to reboot in Mac OS. Agree to this and you will be rebooted to Mac OS.

In reverse when you want to change from Mac OS to Win7 - click on the Apple icon on the Menu bar at the top of any open program.
Scroll to - System Preferences
- System
- Startup Disk
- click on Bootcamp (Windows) icon
- click on Restart
and click on restart again in the next window

This always works for me.
