Can't boot REDHAT since Mandrake 9.1 installed a new LILO

[Albert DE WINT <adwint pandora be>]

Hi Rick, hi Mark, hi Otto, hi other members of the list,

Today I installed Mandrake 9.1.
It installed a new LILO, completely neglecting my RedHat's GRUB.
I suppose it also has written a new MBR?

Now, I can't boot Red Hat anymore.  :-(
I'm both embarrassed and confused.

Here's my partition table:

Device     Boot Start     End     Blocks   Id  System
/dev/hda1     *     1    3616   29045488+   7  HPFS/NTFS
/dev/hda4        3617   14589   88140622+   f  Win95 Ext'd (LBA)
/dev/hda5        3617    4380    6136798+  83  Linux
/dev/hda6        9151    9163     104391   83  Linux
/dev/hda7        9164   14459   42540088+  83  Linux
/dev/hda8       14460   14589    1044193+  82  Linux swap
/dev/hda9        4381    4443     506016   82  Linux swap 
/dev/hda10       4444    9150   37808946   83  Linux

Before I installed MDK 9.1, I removed partitions hda2 and hda3.
(Both used to be dedicated to my former MDK 9.0, so I took them out.)

The partition table is  growing, and I can't figure it out, which OS is on 
which partition.
 
I was told Windows has this nasty habbit of overwriting the MBR. 
Aren't the Linux distro's supposed to have some respect?

Now I wonder how I can correct this situation.

I do have this nice floppy that used to boot RED HAT just fine, but now that 
one doesn't work neither.

Can you please give me a hint.

Albert
