Ubuntu Installer Cannot Detect the CDROM Drive

When the Ubuntu installer attempts to detect the CDROM drive you will be greeted with the following message:

Unable to locate local CDROM

To overcome this hurdle you will need to do the following:

  • press [F2] when the DELL logo is displayed to enter the BIOS.
  • Arrow down until you reach the "Drives" section.
  • Press the right arrow to expand the list.
  • Continue to arrow down until you reach the section "SATA Operation" and press [ENTER].
  • The default setting is "RAID AUTODETECT / AHCI". Select "RAID Autodetect / ATA" instead then press [ESC]
  • save your changes on exit and reboot.

After the PC reboots, the Ubuntu installer will successfully detect the CDROM drive and the installation will push on uneventfully.

* Setting the System Clock using the Hardware Clock as reference…

On Shutdown: -

* Saving the System Clock time to the Hardware Clock…

To resolve this problem, the argument of --directisa will need to be added to every occurence of hwclock in the following files:


Now when you reboot your shiny new DELL 8400 you will not get any lockups from hwclock any more.
