Hi everyone:
I have a WINDOWS NTFS partition from which I want to reallocate space to my Linux one. Can anybody tell me how to do it, is it safe? I rather don't screw up my Linux box.

Cheers.

Some distros claim they can resize ntfs partitions. I never tried that. One would argue resizing partitions is a high-risk operation. But I did resize from within win2k using partition magic 8.0. Never had problems.
Anyway, I would start doing this by a live-cd, which is way easier than installing and configuring a program from scrach. There are three live-cd's aimed at maintenace that you can give it a try:

INSERT - Comes with the captive driver for ntfs rw access.
SysRescueCD - Lots of maintenance programs.
SuSE 9.1 live evaluation - Yast2 seems to be able to resize a ntfs part.

A bunch of live cd can be found in this great page:

on the linux-ntfs site you can get tools for resizing and other operations on ntfs-partitions.
threre are also HOWTO's and faq's . maybe you can try that.

There is a free program to resize partitions that works with most Linux/Unix Filesystems as well as Windows ones. It's QTParted-- a mouse driven gui front-end to the parted utility. There is a boot cd here:

http://www.sysresccd.org/

That contains it as well as a few other tools. I have used it with some success, but I advise (as everyone else does) to back up all the data that you care about before you attempt to modify any partition. There are some tools on that CD to help with backup as well, but I haven't really used them.

I'm looking back at above posts and I see that "bruno buys" mentioned it in his message as well.

Thanks a lot guys I really apreciated your replies. For me as newbie I guess first thing I will to do before atempting any procedure is to learn how to backup my linux data.
Afterwards I will give it a try to one of the tools you mentioned, some windows-based may be.

Good work
Cheers
