Is your usb called Untitled? If not, then this probably is what caused the error in which case, you should erase the USB in Disk Utility and call it Untitled.

Here is how to make a bootable usb of the yosemite installer after you download the full installer app from the mac app store.
Format an 8 GB USB drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Yosemite.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction
You can boot up from it by selecting it from the startup manager you get when starting your computer and holding down the option key.
Did you wait till the terminal returned to a prompt? When I did it, it took about 20 min to make the bootable usb. I used it to successfully install the build 14A389 so I don't think there is anything inherently wrong with the command.
If when you used it to try to install and it couldn't find something, maybe the process didn't finish properly.
where is the recover from time-machine backup option in the OS X 10.10 install media?

I would want a method that creates this partion properly (as is 10.9). Avoiding any extra terminal commands as you suggest.
Read their reply. It IS being created, it is just not visible because Apple has implemented some useless corestorage volumes. The terminal commands remove the corestorage.
Right on. Thanks for answering all my questions, quite concisely I might add.The bootable usb is better than recovery partition or internet recovery because it contains the full installer already.
Well yes there is another way and that is to just run the installer app after it downloads. The problem with this is that if you do it this way, after installing and restarting, the installer will delete itself - without warning.
So it is better to quit the installer after it downloads and opens. Proceed to make the bootable usb, start up from that with the option key and selecting the usb and install from that. That way you do not lose the installer.
