What is the difference between the two Ubuntu partitions on the laptop
(the one that when booted is ok and the one that is not)?

Are you using wired ethernet or wifi?

On the one that fails look in /var/log/syslog and see if anything
obvious is there.  Both when the network fails and during boot when it
sets up the interface.
