Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your log files attached to this bug report it seems that there is a problem with the disk to which you are trying to install Ubuntu. I'd recommend performing a back up of your existing operating system and then investigating the situation. Measures you might take include checking cable connections for your disks and using software tools to investigate the health of your hardware. In the event that is is not in fact an error with your hardware please set the bug's status back to New. Thanks and good luck!
