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…

… and again…

This is my 500Go hard drive.

And this is my 32Go SSD.

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
