no boot =/

[lamwat]

I can't boot on USB Key made with Unibeast.

I had El Capitan, I've upgraded it to Sierra and **** started here (no video, no pictures, no gif, etc...) and then the system didn't even started.

So, I've tried to install it clean. But USB key didn't boot.

I made a USB key with Ubuntu to be sure. Ubuntu works well.

I do not know what do to now. Why the **** I can't install El Capitan again and why the USB key I've used a few years ago to install El Capitan doesn't boot anymore.

How did you fix it?
I think, i´ve got the same Problem.

I create a Boot-Stick with Unibeast, takes forever...
And when finally ready stick it into the hack and boot from the stick.

"Cant boot from the device. Select bootable device..." or something.

Did this several times, no change.
