Help me create a grub entry for slackware

Raccoon1400 · 05-20-2008, 07:57 PM

I just installed slackware to an old desktop.
The desktop now tri-boots. (ubuntu, yoper, slackware 12)
I whiped out lilo so I could boot slackware with ubuntu's grub.
Here is my lilo entry for slackware. What would the slackware entry be for grub?

Code:

image = /boot/vmlinuz
 root = /dev/hdb5
 label = Linux
 read-only

Do you need more info?

not sure if you are using an initrd and I am not an expert on lilo but think pretty good on grub

not sure if you have a slack /boot partition or not....and other drives...read my signature pls

2) assuming all one partition and if ubuntu grub still in mbr and ubuntu or some other drive is on hd0 then try

title slack
root (hd1,4)
kernel /boot/vmlinuz root=/dev/hdb5

3) now I assume in wiping out lilo you can no longer boot slack?

in which case read my trouble shooter and try doing the commands to see if you can boot slack.

I suggest you may have an initrd....but based on vmlinuz...which is a symlink you probably have a symlink to initrd.img

The tab key is your friend.

4) if that gets too hard....boot ubuntu....manually mount slack's /boot partition or folder under slack's / and post the output of /boot....(for slack not ubuntu) pls

your entry booted, but gave an error about how the filesystem had to be initially mounted as read-only. I could continue booting after pressing enter. It gave instructions to fix it, but they were for lilo.
This is a default slackware 12 install. I installed it a few hours ago.
Here is /boot

Code:

root@duncan-desktop:/media/disk0/boot# dir
boot.0300                        System.map
boot_message.txt                 System.map-generic-2.6.21.5
config                           System.map-generic-smp-2.6.21.5-smp
config-generic-2.6.21.5          System.map-huge-2.6.21.5
config-generic-smp-2.6.21.5-smp  System.map-huge-smp-2.6.21.5-smp
config-huge-2.6.21.5             vmlinuz
config-huge-smp-2.6.21.5-smp     vmlinuz-generic-2.6.21.5
diag1.img                        vmlinuz-generic-smp-2.6.21.5-smp
map                              vmlinuz-huge-2.6.21.5
README.initrd                    vmlinuz-huge-smp-2.6.21.5-smp
root@duncan-desktop:/media/disk0/boot#

Okay. Fixed it. Your entry plus "ro" at the end of the kernel line.
Thanks.

glad you fixed it....can you report size of diag1.img....does this open with a multimedia app or could this be an initial ram disk image? (initrd)

I also boot Slackware with Ubuntu's grub. Here are my entries in Ubuntu's menu.lst for Slackware

Code:

# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/sda5.
title           Slackware Linux generic-smp (on /dev/sda5)
root            (hd0,4)
kernel          /boot/vmlinuz-generic-smp-2.6.24.5-smp root=/dev/sda5 ro
initrd          /boot/initrd.gz
savedefault
boot


title           Slackware Linux huge-smp (on /dev/sda5)
root            (hd0,4)
kernel          /boot/vmlinuz-huge-smp-2.6.24.5-smp root=/dev/sda5 ro
savedefault
boot

If you switch to the generic-smp kernel, and you should according to Slackware's changes and hints.txt, you will need to make an initrd. Follow the instructions in Slackware's boot directory to create the initrd.

The first entry above is for Slackware's generic-smp kernel. Note the initrd line. The second entry is for the huge-smp kernel which does not need an initrd.
See post #4 from this thread to use grub's interactive mode to boot any distro:

Don't know if it makes a difference, but I switched to the huge kernel entry.
