Comment 4 for bug 1507448

Ditto - just ran into this exact same issue attempting to install Kubuntu 16.04 onto an external SSD drive. My internal hard drive had full drive encryption on it and so it was completely trashed and I lost all data on it. Like the guy mentioned in the original post, the whole problem could have been avoided with a simple warning telling me that the guided option will install the boot loader on a different drive than I selected to install Kubuntu on and I should choose the un-guided option to customize that.
