I am using debian-live-503-i386-kde-desktop.img. When I use the Restart Computer button, I get the usual shutdown messages until I get the message to remove my USB drive and hit enter. When I do this I get the message to continue with Ctrl-D or Press enter for maintenance. Ctrl-D just repeats this message. Pressing enter brings me to a shell prompt. If I do shutdown -r now it comes back with the above message.
Please advise me on how to do a successful reboot.
