I have installed WinXP and RH9 in my machine. I would like to try Mandrake 9.1 but i dont want to delete any of my OS. I there any way of resize my RH9 partition for install Mandrake without RH9 stop working??

How about the swap partition?? I have to make a new one??

Take a look at "parted" and yes you can use the same swap for each OS (not xp obviously).

The Mandrake 9.1 installer will be able to re-size the RH partition. It claims to be able to re-size Windows partition as well, including NTFS. I used it to re-size a Windows FAT32 partition without problems. It is a graphical partitioning tool which is very easy to follow.

once tried to install Mandrake 9.0 in a machine with WinXp and RH. I resize the RH partition with the Mandrake installation tool but RH dont start any more. Just Mandrake 9.0 and XinXP. I really like to try Mandrake 9.1 but i dont want to lose RH9.

That was probably caused by Mandrake's installer overwriting the bootloader. This could happen again when you install Mandrake, but all you have to do is make an entry in the bootloader for your RH installation. Before you install Mandrake, copy your lilo.conf to your /home directory. After booting into Mandrake, you can copy the applicable RH lines from your old lilo.conf to your new one, and you should be OK. You would then need to copy the newly completed lilo.conf to your RH /etc as well, so that you can make changes to the bootloader from RH if you want to.

Boot into Mandrake and change fstab for Redhat's partition. Also change LILO or grub to include Redhat.

You don't need to make a new swap partition for Mandrake. It will use the same partition as Redhat's.

Hmmm... not as simple as it seems. Look here for an explanation of the pitfalls of using Lilo in this fashion:
