Bug Description

when installing Ubuntu 13.04 i386 image downloaded on 4 April 2013, the install asked me what to do with the drive. i choose to keep the existing partitions, but to format the file systems on those drives. The partition manager stated that this action was undoable at this time. Next i went to set up the keyboard, at which point the X server crashed due to a bug that likely has many bug reports already. when i went to reboot the system, instead of the old system, i was greeted by a Grub error 2. Booting to another Ubuntu live cd, i was able to see those two partitions, but found that the root file system contained Ubuntu 13.04 files.

The installer should not touch the existing system until the user is actually ready, as at the end of the install configuration. it especially should not do so after the partition manager tool clearly states that the actions taken there can be undone! fortunately, for me this is a test system that has nothing on it, but imagine if this was my main machine. what if i change my mind about installing Ubuntu before i finish answering the configuration questions? what if the power fails?

In past releases, nothing was changed on the old system until the user specifically presses an Install now button after the configuration questions are all answered. This is what I expected to happen this time.

I assume that this is done to install things in the background while the user is answering questions to make the total install time shorter, and that is OK. However, it is not OK to change this behaviour with out telling us in the installer, nor is it OK to explicitly state that the partition action is undoable when, once the user clicks to the next window, it becomes undoable.

This is a major issue because it can cause the loss of someone's system.
