    11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    Pew! I'm not sure where to start on this problem...

    A couple of months back i deleted my windows partition (sda1) due to a nasty virus (typical fate of an Win isntallation, isn't it). I then got myself a new HD and installed windows on a different physical HD. After a lot of help i got grub to detect the two disks, but there was still some reference to sda1 left: Every time i booted ubuntu there was a message during the ubuntu loading screen that "sda1 is unavailable or missing" and then options "S" for skip search or "M" for manual recovery.

    Now to the issue...

    I have now upgraded from 10.04 to 11.10 and when the "sda1 missing" message appears and I press "s", nothing happens: The dots under the "ubuntu" screen fills up and then stops loading. All i can do is hit the power switch.

    Due to an issue with an new graphics card, i cannot access failsafeX via recoverymode. But i do however get an command-line via recoverymode as root. So here's what i need help with:

    Can someone please post the code for removing the old reference?

    I got a tip while back that it's probably a reference in /etc/fstab but i'm not good with the terminal... I'm pretty sure that the bootloader is grub legacy and the distro is of course 11.10

    Anyone? Help would be much appreciated...

    It probably is fstab has an old entry. Or with drive order changed, you may have something mounting by device(/dev/sda) rather than UUID.

    Post this and we can give specific suggestions.

    The two map entries are there to trick windows that it's installed in the first hard drive. Not sure that it means anything to you...

    So.. My problem is that somewhere there's a reference to sda1, which doesn't exist and this somehow makes my ubuntu not to boot properly.

    Anyone with pointers to solve this problem?

    It's the reference to sda1 in your fstab file:

    -----------------------
    To edit the file, if you can boot the recovery mode:
    Code:
    nano /etc/fstab
    Remove the line or place a # symbol at the start.

    If you cannot boot to the recovery mode, boot a LiveCD to the Desktop (Try It), then mount your Ubuntu partition and edit the real fstab file:
    Code:
    sudo mount /dev/sda6 /mnt
    gksu gedit /mnt/etc/fstab
    GRUB2

    Retired.

    Re: 11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    Thanx for all the help guys!

    I first tried drs305 1st option. Unfortunately, i couldn't figure out to save the changes, there was commands at the bottom but i couldn't use them.

    I was forced to hit the power switch and go for option 2. And that one worked! Yay!

    Still can't boot an x-session though. Now it ubuntu just freezes before the login screen instead

    The reference is gone though, so for this matter the issues solved...

    Re: 11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    I would appreciate some help with a similar issue I have after upgrading from 10.10 to 11.10 (lubuntu).
    10.10 worked fine after install and after the updates loaded. Then after I did a reboot after the upgrade was done, the screen goes to psychedelic snow and my Caps lock and Scroll lock lights keep flashing - nothing happens.

    I've made a copy of the boot record similar to the original query using the live CD, but am too much of a rookie to know what is going on.

    I do have to note that I previously tried to install Xubuntu 11.10 and Kubuntu 11.10 from a live DVD - with the same problem.

    History of the drive is it started with Ubunutu 8 and upgraded all the way to 11.10, then I tried a dual boot with openSuse. This did not work so I played around with openSuse that worked fine (apart from sound), which is why I decided to go back to the good old trusted Ubuntu.

    Hope someone can help.

    Re: 11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    ehamman,

    Your files look okay except for one thing. Several of your boot files are located pretty deep on the disk. Older BIOS can't 'see' that far (137GB limit) onto the disk until after an OS boots. This may be your problem.

    Boot to the Grub menu, press 'c' to get to the grub prompt, then run the following command:
    Code:
    ls (hd0,1)/boot/grub/core.img
    ls (hd0,1)/boot/vmlinuz-2.6.35-32-generic
    They should return "core.img" / "vmlinuz-2.6.35-32-generic" or "error: file not found."

    If it doesn't find these files, you will need to either shrink your linux partition to less than 130 GB or so, create a separate /boot partition within the first 130GB, or update/check your BIOS to enable large drives (perhaps listed as LBA option).

    If Grub does see the files, you can boot the LiveCD and try to reinstall Grub:
    Code:
    sudo mount /dev/sda1 /mnt
    sudo grub-install --root-directory=/mnt /dev/sda
    Don't use the partition number in the second command.

    You can also try Boot Repair. You can install it on the LiveCD and let it try to fix things. See the link in my signature line.

    Re: 11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    Thanks for that drs305
    I've done the check through grub and it sees both files.
    I've also tried the re-install of grub, but that did not work either.
    Have then gone the route to reduce the partition where my linux reside to 100GB and no luck there as well. This is the only operating system that I'm trying to install so no issues with windows or the like.
    I've actually tried to reformat the drive and rewrite the MBR as well ans still not luck. After the grub menu I am greeted by a snowy screen, the black and then when it is suppose to kick in the operating system I get a red flashing screen with my Caps lock and Scroll lock lights flasing on the keyboard. Boots fine from most liveDVD's, but just not from the HDD anymore.
    I've checked the Bios Rom is ASUSTeK EZ Flash B325. Running on a P5N-MX motherboard, V0202 dated 12/17/2007.

    I'm not worried about a complete re-install at this stage, just want to find some way to get up and running with the drive and an OS.
    The one thing I find weird is that even though it says I got a 500GB HDD, when I get into Gparted I can see only 465GB allocated.

    Thanks anyway - I'll just have to keep searching or just buy a new drive I guess.

    What I have noticed as well, when I try to boot on the rescue/safe boot, then just after it tries to "loading initial ramdisk" it goes into the flashing fit - this time a black and white vertical striped screen.

    Re: 11.10: GRUB Legacy: old reference makes ubuntu freeze during boot

    May also need other parameters which just requires experimentation or search for similar systems and similar issues with solutions.
