Until September i had a Win7 / Ubuntu Dualboot on my IdeaPad S205. Then i installed Win8 on and it runs great, but it destroyed my Dualboot menu. So i decided to install a new Ubuntu again.
I wanted to start a Linux System from a USB stick, but i couldnt.
Trying to install Ubuntu only a short display message shows up: "Secure Boot not enabled"
Nothing happend after this.
Now i tried a lot of things to get any Linux System to run:
I have no ideas anymore.
I dont know what the Win8 Installation changed, but i cant undo it.
How can i start a Linux System from a USB Stick ???

After the "Secure Boot not enabled" message, you have a blank screen right?
Just press the enter key, and your usb linux live cd will start.
The startup menu of the usb live cd is there. You just can't see it.
example, if u press the down arrows u will select another optionn of the menu, but without seeing it, i wouldn't risk it, if you don't want to mess with your windows installation.

I was sure i did already press the enter key at the black screen, but i was going to try your advise anyway.
Now the Grub Menu from Ubuntu/Kubuntu starts direct after booting, even without pressing enter.
I have no idea why. I didnt change anything but set the USB Stick as the first boot device, instead of selecting the USB Stick from the boot menu using the F-Keys.
I will try if everything works with the installation.

Ok, i finally installed Kubuntu after a few attempts.
I deleted all "bootmgr.efi" and \efi\ files from the USB stick and converted the HDD from the GPT to the old MBR.
So the system runs in old MBR/BIOS mode and works pretty well.
I still have no clue why the Live System from USB didnt show up any menu on the display while my attempts last weekend.
Anyway, thanks for your tips.
