Thanks for the info guys. Changing bios from auto to LBA allowed me to boot up XP again. Saved alot of work.

I tried to install Fedora some time ago, and ended up with the same problems that many others have, so I did what was suggested in many places:

Booted with a livecd, unmounted all hard disks and entered this command:
Now, Fedora still saw my /dev/hda6 , which is my /home partition, as free space. So I gave up and continued using MDK 10.
The other day I happened to look at diskdrake, and lo and behold, now even Mandrake sees the /home as free space, which is kinda amusing as it's always mounted and a fully functional ext3-partition.

Now this leaves me in kind of a pinch, as I dare not touch my prescious hda, because it contains all the really, really important stuff. And I spent a lot of time moving stuff around, formatting, erasing, resizing and creating partitions to get that prized separate /home partition.

Can I somehow undo my mistake, because I really don't know what that wicked sfdisk-command really does.

The problem is occuring because the way in which the disk geometry is reported by the Linux kernel is changed in its version 2.6 The geometry reported is called untranslated one and should be translated by the user space program ie. the installer.
This is what exactly is not done by installer and hence the problem.
A very simple solution is to use 2.4 kernel instead of 2.6 during installation. Mandrake does include a 2.4 kernel for installaton.
After booting from CD1, press F1 and type "alt1" and hit enter.
