Live system doesn't work

[clouder]

Hello community,
I have some problems with my Ubuntu Live Stick.
When my laptop starts to boot I don't get the purple screen for choosing an option but I get the Grub Bootloader of the Live System.
There are three options:
* Trying Ubuntu
* Installing Ubuntu
* Check Hard Drives

Selecting all of them has the same result:
The LED light of my USB stick blinks for a few seconds, the screen turns black and nothing happens.

Is there any solution to fix this?

My hardware specs are:

maybe you need to add boot option due to your chipset:

I already tried out no acpi and nomodeset, no solution.
But the odd fact is the purpel screen doesnt show up.
The Live USB System actually works, I've checked it with another PC.
I'm wondering why. As you can see this laptop has many Intel chips.

Edit:
I've recorded my power up because before Grub shows up a short message is shown.


error: "Prefix" is not set.


Maybe this could help.

from the grub menu (hold "shift" key down at bios end process to see the menu), you can either:

- edit the boot line to remove "quiet splash" to let you know the comments while loading

- select "recovery mode" (2d line) then select "repair package"

The clue of pressing "Shift" already told me a guy on IRC.
But it has no effect... also GRUB starts.

Here I uploaded what happened (sorry about the bad quality, the codec sucked):
