well...in your case i would do that from RH.

- boot RH
- mount your Slack -part. ( mkdir /slack ; mount -t ext3 /dev/hdxx /slack)
- edit the lilo.conf file ( probably in /etc ) as follows

add a new linux section :
-------
image = /slack/boot/vmlinuz <---fill in the name of the kernel-image in the /slack/boot )
root = /dev/hda4 <-----fill in the / partition of Slack.
label = Slackware <---the boot-menu item
read-only
--------

save the file and run " #lilo "
should say smth. like : added redhat; added Slackware; added windows.

make a boot floppy before you do that. ( #mkrescue )

Um, yeah. So, sorry, but I was mistaken. I am using GRUB. How do you configure GRUB? I have opened /etc/grub.conf in Vim, but it is all nonsense to me.

well...grub ??? thats all nonsense to me also......

if i were you , i would use lilo ( but...i'm not you ).
if you want to use grub, i think you can post the config-file for someone who knows grub....

Sorry about that, I boot Windows so little anymore that I have not really thought about my bootloader in a long time.
What would I do to use LILO over GRUB?

well....from Slackware.....

-just type " #liloconfig "<---choose expert
-start w. new header
-add linux partition
-add windows partition
-install in mbr

you now are able to boot Slack. or win.

mount the / partition of RH. ( see post #31 )
then edit the /etc/lilo.conf -file ( see post #31 )
run " #lilo "

look at the output ( adding slack...etc )

that's it.

Alright, so I got LILO working fine. But when I added the RedHat bit into lilo.conf using Vim, RedHat does not show up on the LILO prompt.

I can not really post the file here, because I am currently using a different computer. I can not boot RedHat (as I said), and Slackware apparently does not have a GUI today. And windows... <shudder>

So, I have tried various things so far, and none of them are working. Also, for future reference, how do I set the default boot?

Never mind, I got it. Thank you very much, especially egag. I really appreciate the help. This LILO thing will take some getting used to, but then again, if I let that scare me, I would still be using Windows. So thanks a bunch.
