no dualboot yosemite/el capitan

[frankje]

Hello, I installed the el capital developer preview. I did this shrinking my yosemite partition and creating a el capital partition. However on startup it boots straight into el capital. There is no dual boot option, even when I hold down the 'option' key. please help.


grtz, Frank

Go to System Preferences > Startup Disk and change the boot disk.
