Seems to me that

Code:
set root='(hd0,1)'
should be

Code:
set root='(hd0,0)'
from reading your attached grub.txt

I am just judging from the gparted picture though. I use grub legacy to mutiboot/chainload grub2 distros though and kernel line I always use UUID= instead of /dev/sdx.

Your gparted output looks like you have your / filesystem on sda1 w/sda2 as an Extended and sda5 as your swap. No problems with that.

Quote:
set root='(hd0,1)'
The above entry is correct in Grub2 as it counts hard drives from zero but partitions begin with one while Grub Legacy counts drives and partitions from zero. You could boot the Live CD and run the 'blkid' command without quotes to see if is shows the sda1 uuid as "ca4b9caa-cb82-4d9a-a4ce-1ce5ccb0e6da ". I doubt that is the problem.

I have several different version of Grub2 on different operating systems and all of the menuentries for the Linux distributions installed have this line: insmod ext2, they all boot even though they are all ext4 filesystems so I don't think that is a problem either.

That would seem to be the problem and there are numerous sites with info and most of them indicated it worked on 10.04 but not later versions. I doubt any Grub2 modifications will do anything to help.

Hi,

Just checked it again and it seems to be loading ok for me...but yes it is a different file since reinstalling Lubuntu 10.04...not sure why it appears empty for you.

Yeah, this is what I found when I was looking into it...I did try earlier versions to start with but they won't even boot as a live CD, they comeup with the cmov error...but lubuntu 10.04 boots fine and appears to install ok as well.

I did try installing wary puppy as well at one point but that didn't seem to want to boot either...I can't remember what the error message was now but something along the lines of "non-ms skip" but that was using grub4dos

grub.cfg looking good to me. insmod ext2 is there and gparted is also showing ext2.

The output of df -T was made during installation? I wonder cause of the aufs filesystem for root.

My last try on this would be to go with a seperate /boot partition with say 250MB or even smaller. Formated ext2. The rest for / and swap. Whatever the installer does. Reason for this http://tldp.org/HOWTO/Large-Disk-HOWTO-4.html.
Or maybe lilo as a bootloader if available. As far as I know it goes into the mbr as one.

Hi,

I did the df-T command after having done the re-install.

As for using a /boot partition...how would I go about doing this? I assume grub would need to be installed on it...but it usually says that it has to be installed on a linux partition doesn't it?...not sure on how to go about all this?

After the reboot or after the installation was finished? Stupid me. It's after the installation finished cause your system does not boot

Linux Partition for me is just some number inside the parition table. Should be 83 or 82. Its more about the filesystem which should be ext2 so grub definetly can use it. (I'm laying low here just so nothing interferes with the boot process).
So during install you would use gparted and create at least 2 partitions.
The first with say 250MB, ext2 filesystem and marked bootable.
The second with the rest, fs should not matter really so take what gparted has as default choice.

The first parition should be mounted under /boot. The second one for /.

This is all to be extra sure that no bios limitation or similar interfere with grub finding and accessing its partitions. Not sure about this all but worth the try.

Hi again,

Ok, well I think I have done as suggested but still no dice I have attached the latest grub.cfg file and gparted screen.

The grub folder is located on the first 250mb /boot partition

Starting to think this may be one of those annoying problems that never get solved

There is no problem with your partitions or with the grub.cfg file you posted including the earlier one. I think you can modify your partitions, filesystems and reinstall grub as often as you want and it won't make any difference. The problem is with the 'cmov' instruction. The link below at the Ubuntu forums has a little info on it. As I indicated earlier and you seemed aware, this problem supposedly started with version 10.10 and apparently worked with previous versions?? Seems Puppy Linux works, maybe others also??

So even though I am using lubuntu v10.04 you still think it's probably a cmov issue? I did get the cmov error when trying to install newer versions of lubuntu but v10.04 installs without giving me the cmov error, so I assumed that was not the problem?

As previously mentioned, I did try wary puppy at one point but similarly it installed but gave an error on boot...can't remeber exactly what it was though, but I can always try wary puppy again if you all think it's worth another go?

Thanks

As well as Wary Puppy, I think Bodhi and Crunchbang would also work.

AntiX 13 uses a i486 32 bit kernel also for older hardware.

So you have installed Lubuntu and it appeared to complete successfully, no warnings or error messages or problems indicated during the installation, correct? You are not able to boot from the hard drive and do you still get the 'unknown filesystem" error? Your earlier post indicates you have grub in the mbr as well as on sda1. If you are getting some other error, what is it?

Hi,

Yes, lubuntu 10.04 did install successfully without any warning or errors. When I rebooted I was presented with:

verifying DMI pool data
error: unknown filesystem
grub rescue>

This happened every time I installed it using the various suggestions above

I did however have some success after "rokytnji's" suggestion of using Antix 13.1.....this installed perfectly first time and boots ok....I don't know if it will do what I need it to do yet or not...but at least it boots.

It would still be good to work out this lubuntu error though so if anyone has any further thoughts...please let me know

My thanks to everyone for their help and suggestions so far...it's very much appreciated

Cheers

I could say AntiX is Debian Based. Lubuntu is Debian Based. Ergo: anything Lubuntu can do AntiX can do.

But I won't say that because of obscure mistrusted personal Ubuntu ppa sources available on the net.

I have however in some cases installed Ubuntu debs in AntiX and they worked jujst fine when a Debian deb
was not available for download. AntiX has a synaptic package manager which should fit most users needs
and the first thing you should do after a AntiX install is

Code:
sux
enter, type password,enter

Code:
apt-get update
let it finish

Code:
exit
hit enter

Code:
exit
hit enter

open synaptic and install away.

Edit: though with the hard drive space you have. I would not install any thing heavy.

Ok, well Antix seems to be doing what I need so I guess its all sorted. Still can't quite figure out why lubuntu 10.04 didn't work though?

Anyway, never mind...thank you all so much for your help and support....it's very much appreciated

Cheers
