It must be formatted as HFS+ with GUID partition mapping in order for the installer to recognize it.

You can't alter that USB stick because the computer is running from it. Please explain your aim if this doesn't make sense. It is not clear which disk you want to install OS X onto.

Feb 16, 2016 4:29 PM in response to Drew Reeceby Thehumanburrito,I have the Bootable USB El Capitan.
I have a Macbook Pro 13 - 2008 with a fresh never used HD since my older HD crashed before I could copy/clone, and I have zero back ups.
What I want to do is get my MBP with a HD and no OSX to have an OSX. That is why I made this bootable USB.

Boot from the USB stick by holding 'option' (a.k.a. 'alt') at startup.
Select the 'install disk' when it appears & click the arrow to continue.
Select Disk Utility from the list of options that appears.
Select the disk you want to reformat (Apple SSD is the internal disk, Toshiba is your external disk).
Use the Erase tab to create a new 'Mac OS Extended (journaled) disk' - give it a name so you know which disk it is, the installer will change this anyway.
When that completes quit Disk Utility & select the option to (re)install OS X.
Select the disk you just formatted as the destination.
That should get OS X installed on your disk.
It isn't clear to me which disk you want it on so disconnect all the external disks that you do not need - it is easy to install to the wrong one.
