Making El Capitan Recovery HD selectable at boot - possible?


i installed el capitan dev beta 1 on freshly erased , partitioned macbook pro retina. in contrast yosemite , previous versions of os x realized "recovery hd" partition no longer showing during boot (by holding down "alt / option" key). can still boot holding down "cmd" + "r" during boot - before. true both when have encrypted drive filevault also when filevault disabled - differing previous os x versions.

question: there way can manually unhide partition show boot when holding down "alt / option" key during boot?

@ diskutil in terminal shows "recovery hd" of type "apple_boot" should i'm wondering if there hidden parameters prevent being displayed.

i'm asking since goal create dual boot system yosemite , el capitan respective "recovery hd" partitions.

experts highly appreciated!

in advance!
 

it sounds install resulted in corestorage volume. around in yosemite thread , you'll find 1 shows how check , how use corestorage revert command in cli (terminal). assumes aren't using filevault. if using filevault, corestorage required , there no way revert unless turn off filevault encryption.

if don't find let me know, , hunt down instructions you. i've had use couple of times yosemite.

read through following threads, , pay attention on how use diskutil cs list & diskutil cs revert commands.
