Thanks Han. I think it must have been a broken install as I was able to fix as per below:
For the record, after mounting rw and entering safe mode, I used the dpkg fix broken pages menu item which noted that there was a lot of installation needed. I did that and booting worked fine. I had previously tried using a bootable USB and chrooting and running apt-get dist-upgrade however this DID NOT fix the problem. Only the recovery mode did the trick. For anyone in a similar situation, press escape at the Grub prompt. Pick the safe / recovery mode and edit the kernel line and change ro to rw. Then boot up using that configuration and select the dpkg clean. Diagnosing the cause was difficult. It would be great if there was a way to force all the boot processes to debug to the terminal or a USB file / device. -- Karmic hangs during boot https://bugs.launchpad.net/bugs/450253 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
