I have been trying to install Ubuntu 12.10 (64 bit) in my new laptop which has Windows 8 already installed. Initially the usb is booted using efi. But after I select either "Try Ubuntu" or "Install Ubuntu", a blank screen appears.
After searching about that I included
nomodeset option. Then it tries to boot, but hangs in between the process. The last few lines of the output are
*Stopping System V runlevel compatibility [ok] *Stopping anac(h)ronistic cron [ok]
and it's in the same status after which I am forced to shutdown the system.
