Ubuntu 9.04 (Jaunty Jackalope) and Windows 7 dual-boot

In my previous post I talked about the problems I had while installing Ubuntu and Windows 7 on my Alienware m7700 laptop. It took me about three days of hair-pulling before I was finally able to get it to work. First, I burnt a new copy of the ISO for Ubuntu 9.04. Then, I enabled RAID on my system. I put the disks into stripe mode (the FastTrak Promise 378 does not support JBOD). This time, I got past the COMRESET error (ata3: COMRESET failed (errno=-16)) and was able to boot into the LiveCD. However, my joy was short-lived. The install would terminate (around the 40% mark) with the following message:

[Errno 5] Input/output error

This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.
