Comment 10 for bug 1302158

I also experimented this "bug" with the final version of 14.04 LTS but with a weird scenario :

1. You change the boot order in the BIOS to use USB Stick first, Hard Disk second, CDROM third or even disable boot from the CD
2. You forgot that you left a Ubuntu 12.02 LTS or 13.10 install CD or whatever old version of Ubuntu in the CDROM drive
3. You prepare a USB stick with the final version of Ubuntu 14.04 LTS and you insert it in a free USB port
4. During the boot (and following the Boot Order) the boot loader of Ubuntu 14.04 LTS will load (choose language etc.)
5. The correct Linux Kernel shipped with Ubuntu 14.04 LTS media will load the correct Ubuntu Installation aka 14.04
6. When Ubuntu will try to access the media it will not load the files from USB stick but from the CDROM...
     so Ubuntu 14.04 will load the files from 12.02 or 13.10 or whatever version presents on the CDROM
7. You will get the message "No kernel modules were found. This probably is due to a mismatch between..."
8. At the end you can fix it by "eject"-ing the old installation CD or use the same kind of installation media during the installation (obvious but not evident to figure out what was happening in my case)

I assume you might also experiment this kind of bug if you have an old Ubuntu CD in while booting the server with MAAS (PXE)

If you want I can create a new bug report with this weird installation "bug" scenario.
