Ok, so here is the problem:
My second foray into the linux world was with Kubuntu, which I hated. I installed Kubuntu and used GRUB as my bootloader (installing it into the MBR). I recently decided Mandriva Linux is better and wanted to switch, but when I installed Mandriva (which has its own graphical version of LILO) GRUB did not go away. Naturally I could not boot any os because GRUB was configured to boot Kubuntu and Windows and the ndldr was replaced with Mandriva's LILO, so nothing worked. I managed to load Knoppix and modify the menu.lst file and restore ntldr so that GRUB was used to load windows and Mandriva, but now the need to erase that drive and reinstall Mandriva and I would really like to be rid of GRUB.
Additional Info
There are 2 hds:
The master is the one I want Linux on and the slave is where windows already is and I cannot remove the data on the windows drive.
Thank you for any help you can give

What you should have to do is install lilo to the master boot record of the first disk (which I assume contains Mandriva). Your windows section of lilo.conf should just look like Then /sbin/lilo and it should all work fine.

Look at B3 for how to install lilo from your Mandriva partition to the MBR of /dev/hda.

I have tried installing lilo into the MBR of the first disk during the mandriva install. The thing that gets me is that I have tried formatting the disk multiple times. Does formatting not erase the MBR?

I don't think formating does anything except wipe out the partition table (in fact, all the data you had on the drive is still there).

I'm not sure I understand the problem correctly though. You said you used knoppix to edit the menu.lst to make NTLDR be bootable. Grub should be unable to find the menu.lst because it should have been deleted when you wiped the Kubuntu partition.

At the time of Windows installion, was the windows drive the first hard drive or the second? (i.e. did you buy a second hard drive and put the new one as master and the second one as slave?)

When I originally bought the comp. the windows drive was master.
I restored ntldr using the windows recovery console. And the thing about not wiping out the /boot/grub folder is what puzzles me. The folder and data is still there (though I misspoke earlier, I had to create a new menu.lst, but that was it)

Okay. Is there anything else on the linux drive?

What I would do is:

1) unplug the linux drive completely and plug the windows drive into the master slot.
2) Make sure it boots, you should only see NTLDR. No grub, no lilo.
3) shutdown and plug the linux drive into master and the windows drive into slave
4) install Mandriva, be sure to put lilo into the MBR
5) Make sure Mandriva boots up, see if there's a windows option at boot time.
6) if so, reboot and try windows (I have a funny feeling it won't work because windows will think it is master, but that's fixable)
