It happens quite often unfortunately, so it may be more helpful if after boot a message window is display informing users of this
When I saw I could start the install process for a dual boot system from inside Windows for Linux Mint 14 it seemed especially convenient, and it was. Installed. Rebooted. Configured the installation. Rebooted. And, surprise! Re-installation!
There was absolutely NO prior notice to the installation process from inside windows that it was temporary, that was on the option below the Windows installation option. There was absolutely no notification on the first boot to Linux Mint 14 that I needed to select the "Install Linux Mint" ISO icon on the desktop to finalize the installation before making any changes to the system. Since even changing the background image was not preserved, a minor change but glad I did not make larger ones before that discovery.
I understand the convenience and need for temporary installations, but proper notification and enlightenment for first time Linux Mint users like myself would have been nice and it was a hard Aprils fools day joke 24 days late.
I write this regretfully as my first post in honor for other first time users to hopefully save the them from it by also recommending with xenopeek a message window after initial boot informing users of this, maybe inconvenient for frequent temporary installs, but far easier to ignore a window warning than to loose all changes and every downloaded file on reboot.
I have to say though I am greatly impressed so far with everything else. For Linux Ive been using Red Hat since 2003 and it was high time to upgrade to a newer kernel and GUI. And thank you everyone who has participated in making the superb distribution of Linux,
EDIT: PS And Thank you encarnae and xenopeek for your posts here. They are the first things I read after searching for why I had lost everything on the re-boot and how not have it happen again.
