You'll have to reinstall grub, to Ubuntu's root, /dev/sda7, (not sure how to do this), then put this in lilo.conf:

Code:

other = /dev/sda7
  label = Ubuntu

Then run, as root:

Code:

lilo

brianL,

Thats how I do all of my multy booting systems... Each OS has its own boot (grub, lilo, etc...) as it was stand alone and all I have to do is set lilo (In my primary OS) to point me to the drive and thats all.... Very simple!
Good recommendation!

To reinstall grub in ubuntu:

He's asked the same question in the Slackware forum.

To reinstall grub this needs to be run from root:

Code:

grub-install /dev/sda7

or whichever the partition Ubuntu is on.

brianL · 01-10-2011, 10:36 AM

Boot up Ubuntu as a live CD to do as Anisha instructed.

But at this moment I cannot boot into Ubuntu. How could I reinstall grub?

brianL · 01-10-2011, 11:01 AM

Like I said, boot up from the Ubuntu CD, choose the "Live" option.

I gave you the link and it explains everything and is all done from a live cd.

If me.... I would boot in to slackware chroot to the ubuntu drive and ran grub from there grub-install /dev/sd*. BOOM HEAD SHOT!

Be warned: Ubuntu will want to install / to an ext4 partition.
I don't think lilo can boot ext4 (grub "legacy" couldn't either (but maybe things have changed), hence the move by ubuntu to "grub2")

You should be OK if you make sure you use an ext3 partition for / or install grub2

A HOWTO for (re-)installing grub2 is here

It's booting plenty of Slackware 13.1's on ext4.

You could also use LILO to boot Ubuntu directly. First you mount it to /mnt/hd, then you go to its /boot directory and look for its vmlinuz file name as well as the initrd file name. Let's assume its Linux image is vmlinuz-ubuntu and its initrd is initrd-ubuntu.gz.Edit lilo.conf and add something like:

Code:

image = /mnt/hd/boot/vmlinuz-ubuntu
initrd = /mnt/hd/boot/initrd-ubuntu.gz
root = /dev/sda3
label = ubuntu
read-only

Don't forget to add the /mnt/hd (or whatever point you choose to mount on) to the lilo.conf. If you don't do that, LILO won't be able to find it. Then you run lilo.

Thank you, this worked. But I've got several more quetions and I made another post.
Thanks to all of you guys!

Great. Two messed up threads + another one closed. All for one problem.
