    It seemed a safe bet to assume your problem was due to the GPT mix. Either way, providing the output to the requested information will help us to help you. If you don't have a bootable CD you can also reinstall with Wubi and when you get that error, drop to a terminal Ctrl+Alt+F2 and get the output from
    Code:
    sudo fdisk -lu
    Then you can post the results here. Also, the following can provide useful info...
    Code:
    sudo parted -l
    sudo blkid
    (the above commands specify lower case -L, not -1)

    PS if you have wubi installed on C: and the other drive is plugged in you can just run the commands from your wubi install.

    You could've said to press CTRL ALT F2 from wubi earlier ! I'll go over on that PC now and try this.

    From the install, just open a terminal (Ctrl+Alt+T). You can use Ctrl+Alt+F2 but then you need to login and it will be harder to cut and paste (unless you capture the output).

    You can also run the bootinfoscript.It wasn't really clear whether you had a current install going

    It's not a wubi issue. I see you found another thread to post in. I haven't seen anything that might explain this. I have an i915 intel chip (on a different computer) and didn't have any issues except the brightness keys. Here is a thread on this which may or may not be relevant: https://launchpad.net/~kamalmostafa/...l-mjgbacklight

    Just found a bug report that relates to your issue: https://bugs.launchpad.net/ubuntu/+s...el/+bug/805586 (doesn't show a workaround, but maybe someone there has some suggestions)

    Re: Wubi megathread

    Hi there,

    I installed ubuntu 11.04 (32 bits) from Windows XP using wubi. It was working fine for two months until 2011/09/15. Today, when I try to boot Ubuntu (selecting ubuntu from the boot menu with Windows and Ubuntu) it does not access to the grub menu but to the grub> prompt line.

    I have run ubuntu live CD and mounted /dev/sda1, where I have the ubuntu directory. However, I cannot access to ubuntu/disks directory (although I can to ubuntu/winboot or ubuntu/install). When I do:
    Code:
    cd ubuntu
    ls -l disks
    I get:
    d????????? ? ? ? ? ? disks
    -rwxrwxrwx 1 root root 0 2011-07-15 11:18 install
    -rwxrwxrwx 1 ...
    and
    Code:
    cd /ubuntu/disks
    bash: cd : disks: Input/output error

    Do you have any idea about how can I fix this?

    Thank you in advance,

    PS. I can boot Windows but I cannot access to c:\ubuntu\disks either.

    Re: Wubi megathread

    juanvi,

    Your symptoms sound like a damaged filesystem to me. I recommend running CHKDSK in Windows. (You can do this from a Command Prompt window or by navigating a maze of GUI options that ends in one to check the disk's integrity -- I don't recall the exact phrasing, though.) You may need to run CHKDSK two or three times.

    I always get a bit nervous about serious disk damage like this, so if you have the capacity, I recommend backing up everything important that you can from the disk before you run CHKDSK, just in case the damage is so bad that CHKDSK actually makes matters worse.

    If I've suggested a solution to a problem and you're not the original poster, do not try my solution! Problems can seem similar but be different, and a good solution to one problem can make another worse. Post a new thread with your problem details.

    Re: Wubi megathread

    Thanks srs5694,

    I was already running windows chkdsk and, as a result, ubuntu/disk directory has disappeared!! The only output I got from chkdsk was that a corrupted sector was deleted or something similar.

    Now, when I select ubuntu in the windows boot menu, it appears a grub menu with a list of kernels and Windows Vista ¿? (I have XP). But instead of a purple background as usual with ubuntu 11.04, it is white over black. When I select any of them, e.g: 2.6.32-21-generic, I get:

    error: file not found
    error: no argument specified
    error: no such a partition
    error: you need to load the kernel first
    Press any key to continue...

    If I press a key, it goes back to that grub menu.

    I am starting to think I have lost the work I have done on ubuntu

    juanvi, check this out: http://ubuntu-with-wubi.blogspot.com...-rootdisk.html

    Hopefully there is a \found.000 folder with a dir0000.chk directory and your files will be in there.

    Re: Wubi megathread

    Thanks bcbc!

    I found exactly what you told me. I copied the content of this directory as c:\ubuntu\disks, rebooted and I am writting now from ubuntu.

    I really appreciate your help!

    Question Re: Wubi megathread

    I haven't found this problem listed here but maybe someone can help me. I'm running Wubi on Ubuntu 11.04. While I've seen in the introduction to this thread that major problems with Wubi have been corrected for my version I do see one bootup issue that I'd like to know if it has to do with Wubi or something else. I get a busybox message on booting. I'm told the system is "dropping back to a shell". After hitting the exit command a few times I finally boot up into Ubuntu. It's a nuisance but better than my present Win7 startup problems which take hours if not days to resolve. The message contents also state something about not finding the root. My bootlog results txt file doesn't seem to indicate any of this...

    Code:
    ============================= Boot Info Summary: ===============================

     => Windows is installed in the MBR of /dev/sdb.
     => Windows is installed in the MBR of /dev/sdc.
     => Windows is installed in the MBR of /dev/sde.

    When it is said that Wubi is installed inside of windows I don't quite understand that. When I did install it from Win7 I chose in the installation to allocate space for Ubuntu inside another partition on that main drive. Wn7 is on another partition altogether. What can I do to eliminate this bootup snag? I'm thinking of just reinstalling using a livecd and backing up all my current packages and settings. A chore but maybe I don't have a choice if I want a trouble free boot??
    When in doubt, check it out!

    If all else fails, check the plug!

    Re: Wubi megathread

    I see you have 4 drives; which one is set to boot first in BIOS?

    I don't see any immediate problems in the boot script, but let's wait and see what bcbc thinks about the situation.
