Comment 80 for bug 1265192

There are several options in ubiquity that will wipe the whole disk but this is not mentioned in the option description. The patch I'm attaching changes the descriptions for the *_format actions to better reflect that those options wipe the whole disk, including other partitions and operating systems.

The generic text is:

 _Description: Erase whole disk and install ${DISTRO}
 <span foreground="darkred">Warning:</span> This will delete everything on the disk, including other partitions, other operating systems, all your programs, documents, photos, music, and any other files.

I would prefer to get rid of the duplicate messages and just display a simple "your whole drive is going to be erased, everything will be gone, all of your data will be deleted". imho ubiquity is trying too hard to display a custom message, and instead opening the possibility of fault and misinterpretation, by trying to identify what the user has installed and only reporting that (eg. trying to detect a Windows partition, then telling the user Windows will be replaced). There is a possibility of confusion if ubiquity fails to identify a drive or partition (eg. does ubiquity identify encrypted partitions from other operating systems? Does it identify Windows Dynamic Disks? Has anyone ever tested this?) and then simply says "Update Ubuntu" or "Replace Windows", when what it is actually going to do is erase every partition on the drive.

The bottom line is that, if the whole disk is going to be erased, then ubiquity should say so. The old simple message "Erase disk and install Ubuntu" was at least clear that the disk was going to be erased, but now different messages get shown depending no what ubiquity detects on the hard drive, and then the whole drive is wiped without the user being told that was going to happen.
