I just installed Ubuntu 13.10 from USB flash (with Universal-USB-Installer-1.9.4.4). It´s well done. But I got boot problem when I restarted my notebook (Acer Aspire 1410, 2 GB RAM, 250 GB HD, Intel Celeron)

The message appeared on screen:

Gave up waiting for root device. Common problem:
  - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system for the right device?)
  - Missing modules (cat /proc/modules; ls/dev)
ALERT!  /dev/mapper/ubuntu--vg-root does not exist. Dropping to a shell!

BusyBox v1.20.2 (Ubuntu 1:1.20.0-8.1ubuntu) built-in shell (ash)
Enter 'help' for a list of built-in commands.

and prompt (initframs)

How does it solved?

I'm experiencing something similar after upgrading from 13.04 to 13.10. I haven't solved it but can get it to boot by doing the following.

From the initframs prompt try typing "ls /dev/mapper" and see if your root volume is listed. If it is not listed, try waiting 10 seconds and run ls again.

If it is now listed, type "exit" and it should now find the root device and boot.
