Hi everyone, I followed a guide to install Yosemite on a partition to install it to a USB memory stick, as not to lose anything in my main partition. Yosemite runs almost flawlessly despite being run on the memory stick. But as I tried to boot into my main partition I realized that my main partition is labelled as Install OS X Yosemite (or installer, don't recall) probably since I still have the installer in my application folder. I can also see then a partition called 10.9 Recovery and my Yosemite thumb drive. How can I boot to my main partition and not override it with Yosemite? Thanks in advance!
