Wait. What this has to do with Slackware boot? You didnt mention anything related to dual boot in the beginning. Tell me exactly what you are trying to do?

I installed slackware about a week ago and I can't get it to boot up unless I use a USB thumb drive. Originally I was trying to get LILO to work, but I've given up on that. I got to the point where I get a grub splash screen with options to boot either Ubuntu or Slackware. Ubuntu works fine, but when I try to boot slackware, I get error messages.

One more thing- why do my device names keep swapping. It happened again. I think that's part of the problem. Remember when you had me do fdisk -l. I ran it again, look at this output and compare it to the last output:

You issue seems to be similar to what has been posted here: http://ubuntuforums.org/showthread.php?t=419118

Read the post made by Mann1ers

The way that I know of to avoid this is to use UUID which we have already done. Appears to be some setting in BIOS which might be causing this.

As far as dual boot is concerned I have never worked on Slackware. I am not sure how Ubuntu + Slackware dual boot works. I can give it a try though if you could paste the output of:

Code:
cat /boot/grub/grub.cfg

Is it still considered a dual boot if I have slackware and ubuntu on different hard drives?

You could try running the following commands:

Code:
sudo os-prober
then

Code:
sudo update-grub
and see if that helps.

Make sure that you take backup of /boot/grub/grub.cfg file before running above commands.

I don't know if this information helps but this is the fstab file in my slackware kernel:

Code:
/dev/sdb1        /                ext4        defaults         1   1
#/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

Where did you install Lilo, the root partition for Slackware, sdb1?
What's on the usb you say you can boot Slackware with?

Quote:

That's not much help. The os-prober and update-grub will give some output. What did you get? We know you still can't boot Slackware but it might help if you indicated whether you got errors from the commands or it indicated success and you still can't boot.

You can get much more detailed information to post by running the bootinfoscript. Just google it, go to the site, read the documentatio on using it, download it and run it.

The USB is a bootable thumbdrive that I created when installing slackware. If it weren't for that I'd never be able to get into slackware period.

It looks to me like you missconfigured your /etc/grub.d/40-custom file: The exec tail line is not the first line in the file as the comments seem to require.

If I read your grub.cfg file correctly, you have two Slackware boot menu entries. With which one are you having a problem?

The custom one seems to want to chain boot LILO on /dev/sdb, and the other attempts to start Slackware by loading and running the vmlinuz image, with the root=/dev/root option. That looks like it's just what LILO is doing, but - if that's the menu entry you're using, your problem may be (this is just a guess) that the root parameter is not being processed in the "correct" order.

grub doesn't use /etc/fstab -- that's for the os grub's going to boot, not grub itself. grub usually gets its startup from /boot/grub/grub.cfg. Since you can boot to ubuntu, I'm guessing grub's booting from /boot/grub/grub.cfg on the ubuntu disk. Post its contents? I don't know grub well enough (at all) to promise anything, but I've had some experience browbeating it into doing what I want and whoever does shoot this will need it.

You said sda and sdb have switched places. Did that happen just once, or every time, or only when you haven't laughed in the last five minutes, or what? Is there a /boot/grub/grub.cfg on the other disk too? (if so, post that one too). What happens if you wait a minute before trying to boot slack (hit an arrow key or something to stop the autoboot timer)? What version of ubuntu are you on? Also please post the output of `grub-install -v`. You may wind up installing grub-doc and spending some quality time with `info grub`.

Probably single quote should not be there in second last line of fstab:

UUID="54915623-8ff7-4b43-8c41-94485063590f /media/LinuxSlack ext4 defaults 0 0

Try with:

UUID=54915623-8ff7-4b43-8c41-94485063590f /media/LinuxSlack ext4 defaults 0 0

The first two lines in 40_custom are:
#!/bin/sh
exec tail -n +3 $0

I never touched those two lines. I can't boot into either of the two slackware entires. I don't know why there's two to begin with.

/dev/sda and /dev/sdb switch a lot. So far I've seen it happen when updating grub and when rebooting. I have LILO installed on slackware.

Try with:

I caught that error earlier and has been corrected.

In your grub from ubuntu:
menuentry "Slackware on sdb1" {
set root=(hd1,1)
insmod chain
chainloader +1
}

whether it should be 'set root = (hd1,0)' rather than (hd1,1) (since 1,1 is swap partition)?
