Okay, I've got XP Home and RedHat 9 currently on my system, and GRUB runs XP as default boot option, no problems here.

Now, I don't LIKE redhat, and it doesn't work so well with my system's hardware.. I have to keep it through the semester for a class though.

So I'm downloading Slack 10.0 .isos as I write this, and need to determine how I can triple-boot my computer.. I am a little confused as to some of the solutions I've seen, is it really as aggravating to solve this problem as I've seen others implement it? I've seen people who have a "boot-choice" tree for multiple OSes, so they get two choices each time they choose until they reach the distro that they desire to run, this seems to run against common sense, since GRUB's load screen has a lot of space for multiple choices (t looks like anyway,) and I'm pretty new to Linux, and I'm clueless about how to tweak GRUB as of yet..

So, in essence, I want GRUB to give me the options "DOS, Red Hat, Slackware" at the same time, with DOS as the default since I am still mostly using Windoze at this point in my learning experience.. Can this be done? If so, where can I research how to do this, or does anyone have a simple walkthrough to do this once I am ready to install Slack?

If you already have a menu.lst file, just add to it. Here is the important part of mine:

title Slackware, kernel 2.4.26
root (hd0,4)
kernel /boot/vmlinuz root=/dev/hda5 ro hdd=scsi
savedefault
boot


title Libranet GNU/Linux, kernel 2.4.21 (single user mode)
root (hd1,5)
kernel /boot/vmlinuz-2.4.21 root=/dev/hdb6 ro hdd=scsi single
savedefault
boot

### END DEBIAN AUTOMAGIC KERNELS LIST

title Windows on /dev/hda1
rootnoverify (hd0,0)
makeactive
chainloader +1

####title Memory Test
####root (hd1,5)
####kernel /boot/memtest86.bin

Thanks a bunch, seems much more straightforward a solution than most that I've seen..

As encouragement (you already have enough howto): Linda has the right idea. I've done essentially that to get the following coming up in grub each time I hit power (no quotes):

"Lx: Red Hat 9 2.4.xx-xx"
"Lx: Red Hat 7.2"
"Lx: Mandrake 9.1"
"Lx: SuSE 9"
"SMSQ (via W98)" [simulator actually]
"Win 98SE"

so even three isn't a limit.

Good luck,

I _have_ run into problems getting the (hdx,y) in the grub entries just right & can't remember right away what the problem and the fix was (or where the email is). However, I posted somewhere (with grub files and fstab) and got the answer.

I just posted today with more detail (especially about trying to get a reinstall of SuSE accessible from grub) in the new "SuSE" forum.
