Hey all,

I'm running OS X El Capitan 10.11.4 on a 2008 24" iMac. I have a 64GB USB drive that has OS X installers sitting on separate partitions. The Lion and Mountain Lion partitions were created by using Disk Utility to restore the InstallESD.dmg from the Installer.app/Contents/SharedSupport directory for the respective installers. As a result, when I run the following Terminal command:

Code:
sudo systemsetup -liststartupdisks

the /Volumes/volume_name/System/Library/CoreServices for the Lion and Mountain Lion partitions as well as my own OS X bootable volume are listed. These three partitions are available to select in Startup Disk in System Preferences as well.

However, when I created my Mavericks, Yosemite, and El Capitan partitions, I used the createinstallermedia command from the installer apps themselves.

These three partitions boot just fine when I reboot my machine while holding down the Option key and selecting them from the Startup Selector screen. Yet they don't appear in the System Preferences Startup Disk window. Also, when I run the systemsetup -liststartupdisks those three partitions don't appear in the list. When I try to use the command
Code:
sudo -setstartupdisk /Volumes/volume_name

I get the output "Not a System Folder" /Volumes/volume_name/Library/CoreServices

Is there another way to get those three partitions to appear in the Startup Disk list in System Preferences? Do I need to use the bless command?
