uefi: linux live cd/usb blackscreens

0

I have a Medion Akoya P2310 D PC with Windows 8 pre-installed, and I have been trying to install Ubuntu alongside it as well as making a third partition for data storage. After struggling with UEFI for some time, I got the gParted (v0.19.1-4, x64) live-USB to boot, however after the grub menu it shows some logs and blackscreens (Strg-Alt-Del still works, though). The logs are normal gParted logs, as far as I know, except for "Windows is in hibernate mode"(which is wrong, Fast Boot is deactivated and I used restart), and the last log is "Waiting for /dev to be fully populated". Secure Boot is disabled, too, it is not in BIOS mode because windows 8 still boots without problems. Trying Ubuntu (14.04, x64) does not work either, it blackscreens immediately after the grub menu, and using a live CD for gParted does the same.
Is this still a problem with UEFI?

Turns out it was (for Ubuntu at least) only a problem with the graphics driver. I usually use a hdmi and a vga screen (hdmi is the main one) and after reading this post i tried booting with the vga one only, ubuntu suddenly worked fine.
Sorry for posting before doing proper research.
