1 Answer 1

During the install you are asked to partition that part of the disc you want Ubuntu on. At least 1 of these partitions has to be named / (ie. root).

Example image:

enter image description here

The ext3 partition in the image needs to have a mount point name / for the system te continue the install (assuming the 1st one had windows on it (NTFS) and the 2nd one being swap).
