Selecting reboot doesn't reboot

[AJenbo]

When putting the karmic cd in a windows xp machine and selecting to demo and install full system, pressing the button to reboot does nothing.

Summary: When the Ubuntu 10.04 beta 1 disc is inserted in a Windows machine and the user runs wubi.exe the installer application does not reboot the machine when "Demo and full installation" is selected.

Hardware: Tested on Windows 7 32bit netbook and 64bit desktop. User Account Control enabled on both, set to default levels.

Steps to reproduce:
1. Insert the Ubuntu 10.04 beta 1 desktop disc.
2. If prompted, select to run "wubi.exe" otherwise open the CD Drive and select "wubi.exe"
3. At the UAC prompt select "Yes" to allow wubi.exe to make changes
4. When the Ubuntu Menu dialog opens, select "Demo and full installation"
5. The dialog prompts "Reboot required" select the "Reboot now" radio option
6. Click Finish

Expected results:
The Ubuntu Menu closes and the machine restarts into an Ubuntu Demo or Installation

Actual results:
The "Reboot now" dialog closes and returns to the Ubuntu Menu. The machine does not reboot.

Thank you Ryan Maki for the much better description of the issue.
Mine was tested on a XP machine, and I have a report from some one else on a help forum who experiencing the same on his Windows Vista machine.
