is it possible to make just an update from Yosemite?

Make sure you are creating a GUID partition and formatted in "Mac OS Extended (Journaled)"

What I figured out in this installation is that if you are on BIOS version "A12" it wont work, I don't know if the version "A13" do the trick because I jumped directly to "A16", so once you have the latest version (at this time A16) you would be able to boot in the drive you are installing Yosemite, (step 32, 33).

Well, it was de BIOS, with the latest A16 BIOS the bootloader it's working now!

I tried to install CLOVER on UEFI, with the option to write the scripts onto EFI partition, but it didn't make it, I had to copy the files on the EFI partition manually, then rebooted and change in the BIOS to UEFI boot and now I have a "bootloader" working, but once I try to boot the "Yosemite" it only gets on to another black screen, I think I need to add some configs files to boot properly, but sincerely I prefer to boot on USB rather than mess with the clover config. Late night, I would install windows to update my BIOS to A16, i'm currently on A12, maybe the update would help.

Same as before, blinkin cursor on black screen

Sorry, didn't made myself clear, I tried to install chimera (chameleon, stolen and rebranded) and chameleon and Clover as Legacy mode (no UEFI) with no problem at installation process, but once I reboot the laptop I didn't get any bootloader, I only see a blinking cursor with the black screen.

I can't manage to install (chameleon or clover) to boot Yosemite, I installed acording to the guide, and everything went almost perfect, except for the boot. I need to use the USB to boot into Yosemite. Any sugetstion? Hardware: Dell Latitude E6410 nVidia card Solid State Drive 160Gb
