So i finally got around and installed Ubuntu on my Sony Vaio SVE1712C5E. I had to disable secure boot and fix the boot with boot-repair after installation. I could boot both into Windows 8 and Ubuntu.
At school, i had to use Windows, so i rebooted into that. When i wanted to boot into Ubuntu it kept hanging at the purple screen. In "advanced options for ubuntu" i chose for "ubuntu, with linux 3.8.0-19-generic" and there it keeps hanging at "loading initial ramdisk".
Ctrl+alt+del will still reboot.
The recovery mode gives some errors.
