I'm booting OS X from an external SSD on my iMac 2009 27 inch.

The internal drive is divided into different partitions: one for another bootable OS X, another for backup of data, another for Time Machine and then I created another 150GB partition to install Windows 8.1 on it.

The problem is when I try to install through Bootcamp it tells me it's going to create a partition, but I already did that on my own.

So which way do I use to install Windows 8.1 on that partition I created?

Thanks!
