Hey
I'm new to ubuntu and I'm trying to install ubuntu as my primary system
I downloaded the two versions of ubuntu (14.04 LTS) and ubuntu (15.04)
I tried to install the os via usb stick (tried three different sticks) and a dvd
and always the same problem when I chose try ubuntu the system freezes !
So does any one know how to fix it guys ?
Thanks in advance :)

Perhaps, but it mostly likely depends on the hardware.
Post the specs and we'll see :-)

This.
You need to boot with nomodeset. https://help.ubuntu.com/community/BootOptions#Ubuntu_CD_Advanced_Welcome_Page_Option s
-> F6 and select it

press enter to boot , 'e' to edit the commands before booting, 'c' for command-line , ESC to return to the previous menu

Hit the e key on the keyboard, use the down arrow key on the keyboard to get to the line beginning with the work linux, right arrow key to the end of the line, leave a space and type in nomodeset and boot.

I tried it again but not in the end of the line and it worked ! :)
Thanks man

Nice :-)

Now you can test it and/or install. You'll need to repeat the process for your first boot and then, in low resolution/graphics mode, install the recommended proprietary drivers.
The nomodeset (or any other additional option) shouldn't survive a reboot without further user action(s) but if it does you'll need to reverse the changes (delete "nomodeset") in order to have the new drivers properly loaded.
