I just bought a HP pavilion hpe H9 phoenix (i7, 8gb ram, 126 ssd & 2x500gb sata) and wanted to install Ubuntu 12.04 on it.
But the computer seemed to be uefi protected. So I turned this feature off in the bios. Then I succeeded to enter the conf menu in the live usb/cd mode (set language with F2, keyboard layout with F3, etc). I then launched the option to try Ubuntu without installing, but nothing happened: just a black screen.
Is it due to the uefi/efi protection? Is this tower motherboard protected?
Does anyone have an idea about how to install any 'buntu on this tower or any uefi protected PC?
It is the first time something like this happend to me… I think I went through 100 of 'buntu installations before. I can't "live" without it…

There are two issues that I suspect you're conflating:
My suspicion is that you ran into a UEFI compatibility issue, disabled UEFI in your firmware, and then ran into some other compatibility issue. If so, this has nothing to do with secure boot, and in fact it might be better for you to try to resolve the issue in EFI mode, particularly if you intend to dual-boot the computer.
Moving forward, I recommend you answer these questions/perform these tests:
If you're currently booting Windows in EFI mode and you plan to dual-boot Linux and Windows, then your best bet is to get Linux to install in EFI mode. Alternatively, you could install Linux in BIOS mode and switch boot modes after installing.
The Ubuntu installer should start up in EFI mode, but precisely how to get this to happen varies from one firmware to another. You can verify that you've booted Ubuntu (including its installer) in EFI mode by checking for the /sys/firmware/efi directory -- if it's present, you've booted in EFI mode.
