    Glad you got that sorted.

    Yes, you can either synch your bookmarks online - both Chrome and Firefox support that (I've only used it with Chrome) - or you can copy your firefox profile from /home/xxx/.mozilla/firefox/xxxxxx.default
    It should carry everything over to your new user.

    I'd recommend maintaining regular backups using the built-in backup tool - you can set it to backup automatically on a regular schedule and it's possible to encrypt e.g. if you backup to a remote site like UbuntuOne. I normally backup /home and then exclude things I don't want like ~/Downloads and .cache files.

    Possible Cause:

    A late July 2010 GRUB2 update is causing a "no such disk" error (in some cases it may have a "no such device" error followed by a long string of numbers) for some users of Wubi, resulting in an unbootable system.

    If the system does not display the original Windows menu, the most likely cause of the failure is that GRUB2 was installed in the MBR and/or on the Windows partition.

    Solution #1:

    Restore the Windows bootloader with the relevant Windows Recovery CD.

    This is exactly what happened to me. I got access to windows restored by installing Ubuntu from a USB-Drive again. However, when I do that, I can not use my USB-Mouse, a Network connection, and apparently my graphics card (screen resolution is very low).

    I would like to attempt Wubi another time, but how do I prevent getting this same problem again?

    It doesn't sound like you installed with Wubi - if you are installing from a USB stick it's likely a normal dual boot. The wubi/grub issue you quoted has been fixed for well over a year so is very unlikely to be your problem, even if you do use wubi.

    Re: Wubi megathread

    Hi everyone

    I am a complete novice ubuntu user and so the commands and what not are somewhat foreign to me

    I have had wubi installed for about a year and today, as i went to turn it on the first time i was having many crashes and what not. I restarted and was then shown a grub command line where i could press tab to view the available commands.

    i cant remember the exact command but i typed something like boot and got "no kernel loaded"

    I can still boot to my windows 7 partition and looking in c:\ubuntu\disks i have a folder called boot with another folder called grub which is empty

    i also have two files, root.disk and swap.disk

    please could someone assist me further? I have all my code inside here which isn't backed up (i no i no!)

    kind regards

    Ricki

    I would check if you can get the info out of it by using this: http://ext2read.blogspot.ca/ (run tool and open the root.disk).

    The root.disk could also be corrupted (I'd say this is likely) so you should run chkdsk and make sure it's still there. For info see here

    If neither of those work you might have to fsck the root.disk. Probably a good idea to consider moving from a wubi install to a new install as well either by migrating or fresh install if you've used it for a year.

First I recommend running "chkdsk /r" from Windows to make sure there is no ntfs corruption, then boot the live CD, mount the windows partition and fsck the root.disk:

    Code:
    sudo mount /dev/sda3 /mnt
    sudo fsck -f /mnt/ubuntu/disks/root.disk
    (-f means force check even if it appears clean)

    PS before you fsck, you could try to mount it to recover important data, but it's important that you unmount if before running fsck.

    See here for more info

    Sorry for reviving the old thread, managed to back up most of the files... but no luck, as I am still getting the dreaded message about unable to mount files in /etc/fstab.... indeed there is no useful infos in /etc/fstab

    EDIT(the following is with the install CD)

    aufs / aufs rw 0 0
    tmpfs /tmp tmpfs nosuid,nodev 0 0

    I tried to edit the /etc/fstab, but no luck:

    # /etc/fstab: static file system information.
    #
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point> <type> <options> <dump> <pass>
    proc /proc proc nodev,noexec,nosuid 0 0
    UUID= 04A6EE49A6EE3AB6 / ntfs relatime,errors=remount-ro 0 1
    UUID=E694F09F94F07381 / ntfs relatime,errors=remount-ro 0 1

    /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0


    as I am getting the same message

    Any hints are welcome

    In fact

    upon restart I get this content in /etc/fstab

    EDIT (this is in command line without the install CD)

    #use 'blkid -0 value -s UUID' to print the universally unique identifier
    #for a device: this may be used with UUID=as a more robust way to name
    #devices that works even if disks are added abd removed.See fstab(5)

    /host/ubuntu/disks/root.disk / ext4 loop,errors=remount-ro 0 1
    /host/ubuntu/disks/swap.disk none swap loop,sw 0 0

    More hints are welcome, thank you

    First you need to migrate the wubi install to a partition install. Once you've migrated you can remove Windows safely.

    Re: wubi cannot mount, what is the next step

    letank, please add a link to your original problem. I can't recall what happened.

    Editing the /etc/fstab on a live CD won't do anything for you, and marking 3 ntfs partitions as root (/) is incorrect (and random - random stuff usually does more harm than good).

    I'd by publishing your bootinfoscript results. And also confirm what you have done to remedy the situation (fsck, chkdsk etc.).

    But if you have all your data and you like Ubuntu, you could also just reinstall and set it up as a normal dual boot (not wubi).

    Thank for any infos. Still using 9.10 because the Ubuntu partition did not have enough memory to install 10.

    Thanks for editing the code tag. Too early too late to get things straights.

    Running from the cd live I can see the windows and other partitions except the Home partition/folder. After searching and reading, I am a bit confused. It boots to windows without a problem. Do I need to reinstall... redo the grub, I found the root file. Too many bits and piece to connect to make it clear.
    Here are the details of the original post

    Ran chkdsk without founding issues.
    Cannot find good infos on how to write the /etc/fstab file, especially because the system is read only and I have not been able to change the permission, and as you mentioned I have no clues on how to do it right.

    and post 946 has the result of bcdedit. Yes I am clueless.
