i cant boot lilo on slackware, grub doesnt allow i to
 

basicaly ive tried to install slackware but ive allready had kubuntu and windows installed, lilo wont apear,

It would help if you supplied some more details...
- Did you have Grub as a boot loader?
- Where did you install lilo? On the Slackware partition?
- Does anything appear at all? Just your original Grub menu?

These are all my guesses, so please correct me!
If they are all correct, you'll have to edit your Grub configuration.
I'm no expert in Grub (I use Lilo) but take a look at your menu.lst file at /boot/grub in your kubuntu install and add the required lines for your Slackware install.

If you inform us where you installed Slackware (drive, partition) we can tell you which lines to add.

i had it installed on the slackware partition, but then i wrote it over THe MBR, it alowed me to boot on slackware but not un kubuntu, it could not find the kernel (it looked for it by the name of the slackware kernel), then i rename, the folder an then it said it was looking for the original kubuntu kernel(?????!!!!), basicly it couldnt load any modules so xorg didnt start, among other problems

Post your /etc/lilo.conf. It's hard to understand exactly what you've done, although I realise English isn't your first language.
