lilo and grub booting problems

[pevsner]

I installed ubuntu-studio for recording as I get a lower latency than a patched realtime kernel on salix/slack. Now I am having boot issues :-
liloconfig.log =

Code: Select all

Boot image: /tmp/lilosetup/mnt/sda5/boot/vmlinuz-3.2.0-23-lowlatency
Fatal: Setup length exceeds 31 maximum; kernel setup will overwrite boot loader

What's also wierd is the ubuntu install is actually on sda6.
Grub via sg2conf grub completes properly, output=no errors, but only has the boot to salix option.

Code: Select all

sg2conf 1.1.14.1

fdisk -l output:

The ubuntu grub worked, but currently ( after patching rt kernel for salix - cause ubuntu's just too bloaty and crazy dependancies - and I would prefer to use slack) I can't boot into it, even of the 12.04 cd ).

Help would be appreciated.

Simply put: your kernel is too big for the version of LILO you're using.

Two possible solutions:
1) Get a smaller kernel, or use the bzipped version instead
2) Newer versions (>=23) of LILO up the kernel size limit to 62 units from 31. You should upgrade to try to fix it, but I'm going to guess that if your kernel is too big, it's about 5-15x too big, not 2x too big.

Cheers.

Thanks mimyers,
I upgraded to the latest lilo 23.2, which didn't report any errors, but still wouldn't boot the ubuntu-studio.
Oh well, the ubuntu-s grub finds salix ok and works, grub won't boot the ubuntu-s on salix.

[mlmyers]

Hm. When you say "it doesn't post errors," are you talking about when you load Lilo into the MBR, or are you talking about at boot time? Also, how are you switching back and forth between Grub and Lilo so frequently?

Oh well, the ubuntu-s grub finds salix ok and works, grub won't boot the ubuntu-s on salix.

Does this mean you're also switching between the Grub Ubuntu distributes and the one that comes as part of Salix? I'm a bit confused by this statement. Can anything anywhere boot the Ubuntu? If so, you should see if Ubuntu distributes an automatic Grub conf tool. If not, try running Slackware's Lilo conf tool, after backing up your current /etc/lilo.conf. It sounds stupid, but you never know.

Good luck!

What I did in the end was.
Installed grub (via ub-studio disc) on it's own partition rather than mbr, booted back into salix and added a chainloader entry in lilo.conf pointing to ub-studio partition.
# Linux bootable partition config ends

Code: Select all

other = /dev/sda6
	label = studio

This will be my method from now on.

I'm a noob and just about everything in this post is greek to me. However I had a similar problem with Mint and Salix. I installed Mint 13 1st then Salix. I didn't install lilo at the prompt. I then rebooted to Mint and ran Grub customizer. It detected and allowed me to choose what it would display among other things. I hit save and rebooted. Voila!!!! Dual boot Mint 13 & Salix.

Simple and smart!
