High Sierra : impossible to finish installation (not booting on usb after first reboot)

[crashphenix]

Hello everybody !

Since this weekend, i tried to update my configuration without success.
Now, i'm on Yosemite version, installed on a classic hard drive and i would like install High Sierra on a new SSD.

Fort that, i tried to follow the "official" tutorial https://www.tonymacx86.com/threads/...ierra-on-any-supported-intel-based-pc.235474/

Into BIOS, i change these parameters :
- Load Optimized Defaults
- Intel virtualization technologies -> disable
- Internal graphic -> disable

First, i was confronted to "installer is incomplete" during unibeast key creation.
I followed this thread to fix that : https://www.tonymacx86.com/threads/...cted-mac-os-x-installer-is-incomplete.249330/

Now i have a problem from the step 9/10 of the installation.

(Concerning the step 9 which is optional when i try to do it, i have the trouble described in image "no-APFS.jpg")

After formatted SSD and selected it for the installation (image1 in attachment), the system reboot,
I tried to select again USB key (image 2) but the system run directly and i don't see the clover screen (image 3)
Finally i arrived on an error screen (image 4) where it said that an error occurred during resources loading.

I can't figure out why the computer don't displayed the clover screen after first reboot and why i can't finish the installation.

What did i miss ?
Thanks to have read me until the end !

I would appreciate any help
thanks guys !

[UPDATE] : i tried to change some other parameters into bios :
Boot Mode Selection -> UEFI only
Storage Boot Option Control -> UEFI Only
Display Boot Option Control -> UEFI Only
=> No success neither, i'm still not seeing the clover boot screen after first reboot.
I precise that in unibeast, i have selected "uefi mode"

Cheers !
