UNIBEAST 6.0 - USB stick structure incomplete ?

[younopooh]

Hello,

I am using a hackingtosh currently running MAVERICKS to create a USB stick to install EL CAPITAN.
I use for this UNIBEAST 6.0.

I have made severals attempts to create the stick, all successfull from a Unibeast perspective, but providing each time the same result : The USB stick is unable to boot the system (Can't find /mach_kernel).

I searched the site for such issue and notice it is related to a change in chameleon between MAVERICKS and YOSEMITE. However, I am still under MAVERICKS, and the mentionned flag to remove in chameleon.org.plist does not exists in my file.

So I start thinking the issue was not this one.

I restart the USB stick creation process with terminal, Disk Utility and console open to scan what exactly happens during stick creation process. I was able to notice that USB stick is hosting 2 partitions by the end of process, both resulting in a drive poping in Finder : USB and EFI.

I walk through EFI from finder and find the clover structure that should allow proper boot. Therefore, I was thinking the stick was OK. Nevertheless, I switched to Disk Utility to check the USB stick. There, was the difference. Disk Utility is not detecting the EFI volume hosted on USB stick. Worse, when I scanned the USB stick for errors, Disk Utility detected a partition map errors and advise to fix errors.
So I click the Repair button, but then no more EFI volume, and boot prove inefficent, USB stick cannot boot.

Does someone knows about this issue ? Am I the only one to face it ?

Hereunder the log extract from Disk Utility when it detected the partition map error.

So, I tested with the YOSEMITE guide to create USB stick with chameleon boot loader => Fail I tested with YOSEMITE + Clover USB stick => Fail At this point, I am pretty sure something is unusual, as I have been able to create USB stick for YOSEMITE+ Chameleon and use it. So I am wondering if the fail attempt I made last spring to install Win 7 64bit dual boot (and never succeeded) did not damage EFI partition. I figure out by reading this topic http://www.tonymacx86.com/401-install-bootloader-extra-efi-partition/comments3.html that my mobo has specificities about that (ASUS 8-series), and maybe I should first check my EFI partition health before going any further. I'll be doing that this evening. To be continued.

UNIBEAST 6.0 - USB stick not booting

I rebuild my EFI partition as explain in the previous link. I was able to create a USB stick for MAVERICKS install. The stick boot and allow re-install of MAVERICKS.
I was able to create the El Capitan USB stick. But still, when booting with this stick I have the same message :
Loading Kernel /mach_kernel
Can't find /mach_kernel

My installation should be now correct enough to allow proper stick creation and boot, there fore I am a bit puzzled by the situation. Any help welcome.

PS: I noticed the second disk on my machine had multiple EFI partition. Maybe something I should fix ?
