Install Problem: Not finding boot device (Mint 10)
 
It seems this is an inherent Ubuntu error, but the fixes I tried for that don't work. I've posted about this on the LinuxMint.com forums but haven't got an answer yet. I've edited my posts somewhat below -- can anyone help here?
------------------------

I have installed Min 10 on an Athlon 2 GHz machine (Athlon XP 2400+ processor, FIC AZ31 motherboard). Apparently the MB or HD is a bit slow (HD ~ 1 year old). I'm getting an error when booting saying that the root device can't be found, and get pushed to a shell. There are two possible solutions also given on screen --

check rootdelay= (did the system wait long enough?)
check root= (did the system wait for the right device?)
Missing modules ( cat /proc/modules; ls /dev)
ALERT! (root drive ID) does not exist, dropping to a shell

This machine worked perfectly with Mint 7, I was just trying an upgrade. I am assuming the rootdelay is the most likely culprit. How do I change this from the shell?
*Note: original post said 900 MHz Athlon -- I upgraded processor over weekend to the 2400+

I've searched the forum and it seems that adding or extending the wait time is the answer -- but how? I've seen references to a "/boot/grub/grub.cfg" file and a "/boot/grub/menu.lst" file. I don't have either on my system. I have booted with the install CD and can read the hard drive (only one in system) and all partitions just fine. Fdisk -l works too. How do I add a bigger rootdelay??

Found this on an Ubuntu forum:
Users have reported slower than normal detection of SATA hard drives on systems with Intel D945 motherboards in Ubuntu 8.10. This may cause the system to drop to a busybox initramfs shell on boot with a "Gave up waiting for root device." error. Wait a minute or two and then exit the initramfs shell by typing 'exit'. Booting should proceed normally. If it doesn't, wait a bit longer and try again. Once the system boots, edit /boot/grub/menu.lst and add rootdelay=90 to the kernel stanza for your current kernel.

Only problem is my system won't boot after waiting a minute or two... or an hour or two either.... so I can't add the rootdelay.

Okay, investigated the bug. Found this site with a cure: https://bugs.launchpad.net/ubuntu/+bug/518582
The cure is simple --
Boot from the Ubuntu LiveCD and create a file on the affected partition:

sudo mount /dev/sda1 /mnt
sudo touch /mnt/empty_file

This solution works for an ext4 filesystem.

Only it doesn't work for me. I can't mount /dev/sda1. It's there, I booted from the live CD and checked with gparted. Gparted says "Couldn't find filesystem superblock". I opened a terminal and tried to mount /dev/sda1. Mount returns an error -- "special device /dev/sda1 does not exist". Well, it's there -- gparted finds it...

Can anyone help with this problem? I might just have to go back to Mint 7 or 8. Mint 7 worked perfectly on this machine. I really want to put Mint 10 on it though. This is mainly a dress rehearsal for upgrading a couple other machines -- which I won't do if this can't be solved. May as well buy something in a box that works. That would make my wife happy -- could then instant view with Netflix.

Is no one else having this problem?

I ruled out a hardware failure. Reinstalled Mint 7 and it runs perfectly. It seems like the problem is with the ext4 file system, especially with older hardware. I'm going to try to install Mint 10 with an ext3 file system and see if that helps.
-------------------------

I downloaded another Mint 10 ISO and tried that. No luck. Is this computer not enough power to run Mint 10??

Athlon XP 2.0 GHz (2400+), 1GB RAM.

The Live CD boots and runs okay half the time. After running a little while it will hang up. Used a different computer and ISO image for the last CD, and it seems to be worse as far as hanging up than the first one.
------------------------------

by farna on Thu Feb 17, 2011 11:02 am
I'm not getting any help here, but will continue posting in case I figure out the problem.
I downloaded yet another ISO image, this time from a European mirror. It seems to boot better. I installed it, but get the same error as the other installs. One thing I did note that might help someone though -- double clicking on the "Install" icon on the desktop usually bombs out. The computer tries to do something and quits, returning to the desktop. If I select "Install Mint 10" from the menu, however, it works fine.

Since the problem appears to be in the ext4 file system, I booted from the live CD and reformated the partitions using gparted to ext3.

I then proceeded to install Mint 10. Rebooted and get the same error as in the first post! So the ext4 file system isn't the problem, as the Ubuntu board alluded. It has to be in the Mint 10 (or Ubuntu) loader.
------------------------------

Okay, anyone have any bright ideas???

Boot from a liveCD and reinstall grub2 using these instructions:

https://help.ubuntu.com/community/Gr...0from%20LiveCD

use METHOD 3 - CHROOT

before exiting the chroot update your initrd with

Code:

update-initramfs -u -k all
then update grub again

Code:

update-grub
and exit chroot with <CTL>-d or type exit

farna 02-18-2011 04:27 PM

This didn't work. I can't mount /dev/sda1 (my root/boot hard drive). fdisk -l finds the drive, the extended partition, and the swap file partition, but when I try to mount the drive I get a "special device doesn't exist" error.

andrewthomas 02-20-2011 06:54 PM

Go to

http://bootinfoscript.sourceforge.net/

Follow the instructions and post the results with your reply

Larry Webb 02-20-2011 08:12 PM

You keep saying trying to mount the drive after you have already mounted it, try this and see if it will help you.

sudo umount /dev/sda1

sudo mkdir /mnt/sda1

sudo mount /dev/sda1 /mnt/sda1

Now using the /mnt/sda1 will take you to the partition of sda1, I do not understand what you intend to do once you are there. Your computer should have enough to run ubuntu 10.10. I do not understand, if Mint 10 works then ubuntu should work. Use Mint, it uses ubuntu repositories I believe and they say a remake of ubuntu. The motherboard may be old enough to give some I/O errors. I would rather think that ubuntu may have a different default monitor resolution or frequency that is causing your problem.

farna 02-21-2011 05:01 AM

I'll see if I can get the Boot Info Script downloaded on the machine in the next few days.

Larry, I never mounted the drive. I can install and run Mint 7 with no problems at all. The video card and monitor are fairly recent, that's not an issue. Mint 10 (based on Ubuntu 10.10) boots and runs from the Live CD with no issues. It just won't install and boot. Once running from the Live CD Mint 10 doesn't find the hard drive. fdisk does, but Mint 10 won't mount the hard drive. It installs from the Live CD with no errors reported.

Larry Webb 02-21-2011 06:25 AM

I ran into a similar problem with a Suse install on an computer I believe it was an intel 915 but not sure. On their install on Suse 11.3 they use a 1440 X 900 resolution that my monitor would not handle. You can adjust this before the install. The boot info script would be the first thing to look at.

farna 02-21-2011 08:23 PM

Larry, screen resolution doesn't appear to be an issue. The Live CD boots fine and uses a high resolution --1280x1024, 17" LCD monitor, Radeon 9200 Pro video card (I think it's 256MB).

Andrew, the results from boot_info_script is below. It says something about Windows being installed, but Windows has never been installed on the hard drive in this computer as far as I can recall. I had to replace the HD shortly after I started running Mint 7, and never installed anything else on it. I'm new to dealing with Linux much on this level, don't really know what I'm looking at/for here!!

Have you tried adding a file system parameter?

Code:

sudo mount -t ext4 /dev/sda1 /mnt
If it doesn't work, your best bet may be to zero out the drive and start fresh.

syg00 02-22-2011 12:45 AM

Do you still have the Mint 7 CD ?. Run that up and re-run the bootinfoscript. A quick look at the script makes it appear that it relies fairly heavily on the blkid output.

farna 02-24-2011 08:24 AM

Syg00, here is the Boot Info for Mint 7. I booted from the Mint 7 LiveCD then ran the script, Mint 7 wasn't installed. Note that Mint 10 is reported as the OS installed on /sda1. Do I need to install Mint 7 then run the script?

Code:

If it doesn't work, your best bet may be to zero out the drive and start fresh.

I see from your post that sda1 is ext3, so if you try to mount with:

Code:

sudo mount -t ext3 /dev/sda1 /mnt
Does it mount?

Nope, that's fine.
Shows that Mint7 can read everything o.k. - must be a problem with mint 10 (I run it {N.B. - LMDE} with btrfs o.k. BTW). Raise a bug against it.

No, still doesn't mount! I get "special device sda1 does not exist". That's when booting from the Mint 10 LiveCD. Mint 11 is supposed to come out in May, so I think I'm just going to give up on 10 and wait for it.

Just for giggles, what is the output of 'mount' with no arguments from the liveCD environment?
