Can't install El Capitan, stuck at boot screen.

[STiX_MAC]

So i'm kinda new to this but recently i decided to install el capitan with efi clover on my toshiba laptop but for some reason i can't get past boot screen. I get the error 255 as well as the garbled screen. I followed this guide: http://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/ step by step and i patched my bios for the DVMT pre-allocated memory with this guide: http://www.tonymacx86.com/threads/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3.162062/ since the clover patch method didn't work. I tried different versions of FakeSMC even changing folders than the "Other" didn't help. I tried booting with injected kexts but nothing.

My laptop's specs are:
System: Toshiba Satellite S50-B-15N
CPU: i5-5200U
Graphics: Intel HD5500 + AMD R7 M260, 1920x1080

Here are some photos to get a better picture of my problem along with my EFI folder.

EFI Folder: EFI.zip

Please if anyone can help me solve my problem, i will be grateful forever.

Note that I said nothing about disabling UEFI...

Keep UEFI enabled, but enable legacy/CSM also.

Your BIOS does not provide the option to have both (somewhat uncommon, as it is required to boot Win7 in UEFI mode).

If you implement backlight control, your issue will likely be fixed: http://www.tonymacx86.com/threads/guide-patching-dsdt-ssdt-for-laptop-backlight-control.152659/

Also, closing the lid, then opening it can help in the interim.

Hmm, correct me if i'm wrong, i assume the guide you provided is for those who already installed el capitan but i haven't installed el capitan yet. The problem occurs when i'm trying to boot into the installer.

For booting the installer, you can simply disable the graphics drivers.

The specifics depend on the hardware configuration, which you have not provided. Please fill out your profile as requested in the guide.

You can simply boot without Intel injection (config.plist/Graphics/Inject/Intel=false).
