Recovery Fails to Boot and Restarts OS

I have a macbook pro mid 2009 15", os X El Capitan 10.11.6

Everything worked fine until I partitioned to a FAT volume. (I don't know if that's the actual problem)

So,

OS still works fine. But I can't boot into Recovery HD anymore, even though everything from Disk Utility returns no Faults.

What led to the ?problem?

I repaired the OS volume, because it said it was faulty (i did that from recovery disk utility). And then I partitioned the Disk into FAT because I want to install windows (no bootcamp comments please). Then tried to boot again to recovery to disable the csrutil but it pops black lines with white letters on the grey screen with apple logo and restarts.

Why is this happening? My issue is on recovery boot. (pram reset didn't help)

MacBook Pro, OS X El Capitan (10.11.6), 15" mid 2009 2.53GHz

So I suppose that partitioning the disk something corrupted the Recovery Partition

and after some days digging the net I found a simple app called:

"Recovery Partition Creator" (ver 4.0.4 is the one I used).

Three easy steps:

1) Download "Recovery Partition Creator"

2) Download the OS version you have currently installed from App Store (1h-3h depending on internet speed)

3) Run Recovery Partition Creator and follow the instructions.

Done in ~7mins.

also to add that i used gdisk to change the hybrid mbr, and that's the reason i needed to get again into recovery terminal. (for the "csrutil disable" command)
