This is a very quick guide on making the Recovery HD partition usable in El Capitan, bootable via Clover.

1- " diskutil list "
* you will get de partition list, note that the Recovery Partition is obviously named " Recovery HD "...
* check the number of the partition it is in, in this case, 3:, so, you will have disk0s3 as mount device...

/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *240.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS El Capitan 239.2 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3

---

2- create a folder in Volumes folder for Recovery HD and mount it there...
" sudo mkdir /Volumes/Recovery\ HD/ "
" sudo mount -t hfs /dev/disk0s3 /Volumes/Recovery\ HD/ "

3- enter the directory and remove the " prelinkedkernel "

" cd /Volumes/Recovery\ HD/com.apple.recovery.boot/ "
" sudo rm -rf prelinkedkernel "

4- now, copy your working prelinkedkernel there...

" sudo cp /System/Library/PrelinkedKernels/prelinkedkernel /Volumes/Recovery\ HD/com.apple.recovery.boot/ "
and just in case...
" sudo touch prelinkedkernel "

5- reboot and test it... (takes some time to load even in real macs)

 

Enjoy!

This tutorial must be for Chameleon and Enoch users. clover automagically creates the RecoveryHD if you use the createinstallmedia method to make usb, The recoveryhd that clover makes works flawlessly, myself having reinstalled OSX from there, without problems, you just need to boot it with injected kexts :D
