Thanks for your reply. Your BIOS seems to startup a bit faster, which BIOS version do you use? Do you have any experiences with the BIOS settings? I see no differences when I enable / disable the UEFI boot option.
To speed up your boot time, you might try to install your operating system on a solid state disk, this reduces the boot time of my linux from about 60s to 35s.
I am now using BIOS version 4905. The boot time in that post was using an older version, but I haven't had time to update that post yet...
I have disabled ALL boots devices and enabled UEFI boot only. However, by doing so, you will not able to boot from traditional MBR-based system, so it is not recommended.
By the way, I am quite surprised that using SSD can reduce the boot time so significantly...
