When trying to start Ubuntu from my USB key in UEFI mode (it works in Legacy mode, but I have to keep Windows) on a Dell Inspiron 15z , Grub starts, but when I choose any option, I get a black screen and my USB key stop teling me it is being read.

EDIT: when using the legacy mode and trying to install Ubuntu, I get a blank partition table with Ubiquity…

Ubiquity doesn't see any partitions

… and a very strange partition table from GParted (I have a hybrid 32Go SSD + 500Go HDD disk) :

An error about the GPT table not at the end…

… and again…

This is my 500Go hard drive.

And this is my 32Go SSD.

Thanks everyone, I have found the solution, I had two problems:

Ubuntu didn't want to boot in EFI mode, except when the firmware was set to Legacy (and let me boot using EFI ¿).

I just clicked "Fix" in all the question screen-shots and then, GPARTED let me change everything I wanted and Ubiquity let me install Ubuntu !

The installation has just finish and I'm going to reboot now.
