Following the recomendation by Reed9 I Installed Linux Mint 7 in a multi-boot system (Windows Vista-Linux Mint).
As suggested by MikeTbob I have created 4 partitions for Linux Mint
(5 GB(SWAP), 15 GB for the system Linux Mint 7 (EXT3), 15 GB (EXT3), 13 GB (EXT3) ) .
I liked very much Linux Mint 7. Now I have two questions:
1) Does there exist some applications in Linux corresponding to MiKteK, Technicenter and WindEdt (LaTeX) which I need for writing mathematical papers?. I did a search in the web and apparently there is a version of MiKteK for Linux but I couldn't save it for some unknown reason.
2) I cannot access the two last 15 GB (EXT3), 13 GB (EXT3) partitions (When trying to access I see a folder with the title "lost+found" but get the message "You do not have the permissions to view the contents of "lost+found"" when I try to access there), what's happening there?.
Many thanks for Reed9 and MikeTbob. Linux Mint 7 is really friendly.
