Well, assuming that you are using LILO, here is what you can do. Boot off of the CDROM for slack. Once it loads up, you get to a login. Login as root. mount your root and boot partions (assuming that they are separate -- I personally like it that way.)
mount -t ext2 /dev/hda2 /mnt/linux/boot
mount -t ext2 /dev/hda3 /mnt/linux
that is how mine would look should I dual boot (I dont but thats beside the point I suppose...)
now do a
that should reinstall lilo. If you get any errors, it should say. If you dont get an error, eacho bootable partition should show up. if you see just linux, you want to edit /etc/lilo.conf to include the partition that includes Win2K.
As for just making floppies -- I dunno. May be able to skip up in the setup and go straight to it. I do know that skipping straight to lilo's setup is not allowed. I don't know exactly why on that one. You should be able though, to get into slack and get most of this done just fine. I do know that RedHat is very simple, and thats what I have got addicted to as of late. But I had used slack quite a bit, and in fact started using slack back when I first got into linux.
