Since Office 2016 came out, I wanted to get it but seeing you need 10.10 minimum I thought of upgrading. I downloaded the Yosemite update from the App Store and went through the process, it restarts telling me the install will continue on after the restart, but I just restart back into my Mavericks as if nothing happened. Any help would be appreciated.

Thanks:D

If you are using Clover and booting EFI then you can update by just running the install Yosemite app.
If you are using Chimera then you need to create a UniBeast USB installer and install with that.

I am using Chimera. So once I create a USB installer and what not, I just install it? will it ruin my dualboot system? Ill probably have to reinstall some kexts right? and finally would it be just an upgrade? meaning would I lose any data or everything will stay the same but will be Yosemite?

Thanks:D

Will not ruin your dual boot system unless you reformat the HDD. You can either install overMavericks and it will just update the core/kernel and leave all your settings and apps in place, or you can erase the Mavericks partition and install Yosemite clean to the erased partition.

One thing to remember is to edit the org.chameleon.boot.plist to remove

<key>Kernel</key>
<string>mach_kernel</string>

I would remove it before installing Yosemite. You do not need it anyway - it is a holdover from earlier system requirements.

Forum search for key words Yosemite + can't find mach_kernel will explain why you need to do this.
