Trusty Boot Problems Vaio Fit

[Holger]

Hi everyone,
need some help on an issue which came up installing Trusty on a Sony Vaio Fit 
11A. So far I was able to install the system to the hard drive booting from an 
USB connected external CD-ROM drive. After the install process was successful 
finished the system boots up in the recovery mode only until the lines "udev 
start/running, process 227". Afterwards it just stops booting further. Tried 
different things but I am just a bit lost. This happens also no matter if UEFI 
is switched on or off. Same results, same procedure.  

Additional note: On the final stage of the installation process pressing the 
enter key to reboot the system ended up in not being recognized by
the system. Laptop on/off was the way to move forward.


Any ideas how to manage this???

Thanks

Holger
