[Bug 808015] Re: Installer Crashed Errno5

[Brian Murray]

This bug actually has all the information necessary to determine the
problem.  In syslog we see the following:

This generally indicates an error with your media, however given your
statements regarding the work you've done it likely isn't the media but
possibly the drive itself.  I'd try cleaning the drive and or checking
the cables that connect it to your motherboard.

  days now, I have tried different CDs thinking making the info got
  corrupted during the burn, I have slowed the burn speed down, I have
