Thanks! But I did a re-installation of linuxmint! The problem was that I wanted to separate the "/boot" and the "/ " because of reading it on a site. Apparently those 2 belong together! ....I have 2 HDD in SATA, unplugged my second HDD to be sure to install on the first one. After installing I tried aMsn again (that was installed by default) but it told me that there was a newer verser and that I had to download it! Because of the fact that I had an older version my webcam couldn't be configurated. So my question again is:
1) How can I uninstall aMsn? When I do this with synaptic, will there be dependencies left on my drive of the old aMsn? will I still need them with the new version (0.97R) of aMsn? or how can I delete them?
2) Synaptic Package Manager contains dependencies where I have no knowledge about. I even don't know what they're used for. I was told that when you install a package, the dependencies needed for those packages will install by themselves if necessary. Is that true? So when uninstalling packages, the dependencies will leave to? No orphan packages anymore?
3) After uninstalling aMsn, how can I easily install this from their site? Because we've got a lot of possibilities! For Linux, windows, packages, etc..... I know that the packages has to be compiled, but I'm not that far yet in understanding building packages! If I take the tar.bz for Linux, I have to open a terminal and type the code: tar -jxvf <filename> but never the less it won't be configurated! In Ubuntu I had Gdebi to install my packages. I found Gdebi in System Tools here in LinuxMint, but it can't see my desktop!?It is empty! So I suppose I have to cut and past the packages, downloaded on my desktop, in my home folder? (How come Gdebi don't see anything on my desktop?)
4) How to configure aMsn for the best? In preferences you find a lot of things that you can change and install, but to have audio possibilities or webcam images (because I suppose that the two still don't work together?) how to do this? What should I use for sound preference? The Snacklibrarie installed by default? or another one? what is the code for that? The other items above, about the home folder, email command, etc.... where can I find all that? The help is apparently not installed, for nothing of all my applications I saw, so how to install help function for my complete OS?
Well, I hope that someone can help me on at least one of these items.....

That would be great!

Thanks a lot.
