I experienced two issues trying to install Ubuntu 14.04 x86 on my old laptop today:
- ubi-partman crashed (I clicked Continue)
- Installation hung Getting the time from a network time server
I encountered these issues booting from DVD and then clicking on the Install Ubuntu button in the installer.
Fortunately I did not encounter either of these issues when I rebooted and then clicked Try Ubuntu in the installer and then installed Ubuntu from the Live DVD session.
