Thanks for your answer!
MY LINUX CONFIGURATION - LACK OF GNOME AND KDE
The following is the result of using those commands (it is only my translation because I've got other language version than English):
Code:
Choice=U=Unknown/I=Installing/R-Remove/P-Clear/H-stop|Start=N=None/I=Install/C=Config/U=Unpack/F=NotConfigured/H=HalfInstalled/W=Wyzw-czek/T-Wyzw-zp/I/Errors?=(none)/H=Stopped/R=ToBeReinsalled/X=Both(State,Errors:capital letters=bad)
||/Name Version Description
+++-===
ii grep 2.5.3~dfsg-6
GNU grep/egrep and fgrep
Packet to template gnome not found.
(And the same for kde).
MY CONCLUSIONS
It looks like, surprisingly, I have installed neither gnome nor kde. This is surprise for me because I followed ordinary installation of Debian, withouth changing anything (except partitions, of course, because I've got now both Windows and Linux).
WHY I NEED LINUX - TO COMPILE CODE AND EXECUTE PERL SCRIPTS
I need to have Linux because I've got some problems with compiling CMU Sphinx from Windows. (It is described here: ht tps:/ /sourceforge.net/projects/cmusphinx/forums/forum/382337/topic/3439692 (remove two spacebars from URL) so if you can help me, I would be very greatful). Installing requires compiling some source codes, running some Perl scripts and so on. It didn't work in Windows (as explained in the link) so I decided to check it in Linux.
PRIVILIDGES OF LINUX PARTITIONS IN DEBIAN AND KNOPPIX
I found DVD with Debian and CD with Knoppix. But it looks link I need to download Ubuntu DVD because neither of them is helpful for me - Debian because of not having graphical interface (it is minor issue) and not having automatic mounting pendrive (major issue). And Knoppix because it cannot unpack anything to Debian ext3 partition (because only owner of ext3 partition, i.e. root of Debian, have got all privilidges, "others" have got right only to read. I guess I can somehow change it under Debian, i.e. create group of Knoppix users, add it to groups connected with this partition, change privilidges or something like this). Unfortunately I'm rather used to Windows, than Linux

. I guess I need to improve my knowledge about Linux soon

MOUNTING LINUX PARTITIONS UNDER WINDOWS AND FORMATTING PENDRIVE FOR EXT3
I also tried something else, i.e. access to Linux partitions on my disk under both Windows and Mandriva. Unfortunately, under Windows my attempts didn't help. I installed Total Commander with plugin wfx_ex2fs_1.3. It has got one additional field in "Network places", i.e. Linux-drives but it opens only hda6 and hda8 which are, surprisingly, empty. The other way was to format pendrive with the use of Partition Magic 7.0 and it can see only my disk (all Windows and Linux partitions) but it doesn't see pendrive. The third approach was to format pendrive for ext3 with the use of other programs than PM7. I installed SP27608. It is "HP USB Disk Storagte Format Tool, V2.1.8 and it should enable me formatting pendrive for ext3 - it doesn't. The fourth approach was to access ext3 from Windows in other way than TC7 with plugin. I installed Ext2IFS_1_11a.exe and it sees three additional disks in My Computer but it cannot open any of them - it wants me to format those.
SUMMARY OF MY PROBLEMS
So please help me

:
1. first of all with this (if you can): ht tps:/ /sourceforge.net/projects/cmusphinx/forums/forum/382337/topic/3439692 (remove two spacebars from URL)
2. how to mount pendrive (which is FAT32) under Debian / how to format pendrive to ext3 under Debian
Thanks in advance for your help!
Greetings
