I want to uninstall mandrake 10 so i can install suse linux 9.1.
Booting from the suse cd does not work because i dont have the boot floppy.
Does anyone know how i uninstall mandrake???

Uninstalling is quite easy. If you're dual-booting with Windows use a Windows boot disk and run fdisk /mbr or from Linux lilo -u (as root), but the second option will only work if LILO was installed only once (if you have changed your LILO configration, it will not work). If it's a Linux-only machine, you don't have to remove LILO.

Now you can remove the partitions (or only format them if you wish to keepr the scheme; if you have separate /home and wish to keep your configuration and files, don't format it).
All the partitioning can be done during SuSE installation, so the most important thing will be to boot it somehow.

Suse doesnt require a boot floppy. Are you sure you burned your ISO correctly, or is this the storebought version? If it is the storebought, check the documentation. It makes a note of booting from CD2 if for some reason CD1 doesnt work. I guess it was a know issue...
