Comment 16 for bug 45989

This just happened to me in an upgrade from 9.10 to 10.04. The installer confuses my two hard drives, switching the labels from dev/sda to dev/sdb and vice-versa. It had also installed / (root folder) folder on my backup drive (where I keep backup of my /home partition). This ultimately led to a loss of important data because I had become confused about what had occurred. It also installed the MBR on the wrong drive (my backup drive) which caused me to have to repair the MBR.

This was REALLY frustrating.
