    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!

    I haven't tried this myself yet so am not sure if it works, but apparently if you boot into recovery partition, you can in the start up disk, boot into mavericks again.

    In the middle of several books.
    Boot into Yosemite and go to Preferences > Startup Disk. Pick Mavericks as your default HD. Reboot your Mac holding down option key. You should now be able to see all your different partitions and will be able to boot into Mavericks etc.

    Reboot Issue?

    After all this, when I go to restart my machine from yosemite to Mavericks; it seems to take a long time; I've not had the patience to sit and wait to see if it is going to actually boot into Mavericks I just hard reset at that point, but has anyone else had this issue?
