    Coming to the issue of migration, I created sda 5 of about 45GB & a small sda 6 of about 1.5 GB for swap as detailed in this thread:
    http://ubuntuforums.org/showthread.php?t=1519354. This is in addition to sda 1, 2 & 3, where Windows 7 is installed.

    When I tried to execute the command for "migration with swap file" in the Terminal, as detailed in the above thread,It says sda 6 is not a swap partition. What does it mean? All the sda's are NTFS formatted.
    I responded about the script error in the other thread. In future, you should just ask in one or the other

    Regarding Wubi going to a grub prompt - you should run and post the results of the bootinfoscript so we can figure out what happened.

    Boot problem

    Hello,

    Till now, I had successfully been using my Ubuntu 11.04 installation, installed through Wubi. Now recently, I was having some network problems, and booted on to Windows to google something up. When I restarted to test the latest development on the network problem, I was greeted by the following message in GRUB2:

    error: no such device /ubuntu/disk/root.disk
    error: no such device /ubuntu/install/boot/grub/grub.cfg
    error: no such device /grub.cfg

    (REST OF THE ERROR MESSAGE IS NOT EXACT, AND IS FROM MEMORY)
    Cannot boot from Ubuntu disk image.
    Please make sure that you have not removed the Ubuntu installation.
    This could possibly happening due to a corrupted Windows NTFS filesystem, and can be fixed by running 'chkdsk /r' in Windows.
    NOTE: GRUB2 quickly displayed the error message and went into command line mode, so I couldn't grasp the message. To reproduce the above, I typed in 'configfile /wubildr.cfg'.

    Now, I tried running both: 'chkdsk /r' and 'chkdsk G:' but it didn't work. Then I read somewhere that perhaps they copy the files in a hidden folder 'C:\found.000\'. However, this folder didn't exist.

    Now, I have some very important files in the Ubuntu installation, and I want it back. Please someone help me?

    Regards,
    Shikhin

    Hi and welcome to the forums Shikhin

    The first step in trying to figure out what is going on would be to post the results of the boot info script here.

    There is a link at the bottom of my post with instructions.

    If you need to download and create a LiveCD/USB, you can find the images and instructions here:

    I used Puppy Linux, and here is REPORT.txt:

    And somehow, even though I have enabled "View Hidden Files and Folders", I couldn't see found.000 in G drive. However, using Linux I found it. Now the only question, is, I found the following files in it:


    - root.disk
    - swap.disk
    - /boot/grub (empty directory)
    Where do I copy all of these files in the Ubuntu folder. If you can respond quickly, .

    Regards,
    Shikhin

    Re: Wubi megathread

    Hi,
    Here is what you need to do:

    Move the root.disk and swap.disk files back to sda3 (G drive I assume) and place them in their folders with the following structure:

    \ubuntu\disks\root.disk
    \ubuntu\disks\swap.disk

    Next, make a backup copy of the root.disk to an external medium such as a USB stick in case this happens again.

    Finally, reboot and see if everything is normal again.

    You may need to apply solution # 1 to problem # 2 from the main post (but first see if Ubuntu boots normally).

    If not, run the boot script again and post it here please.

    Thanks.

    Re: Wubi megathread

    Hi
    Just wanted to update the forum. Solution 1 worked for the problem 2 for me.

    I have 10.04 of wubi. Is it worth moving to the latest ubuntu (11.xx)
    If so how can do it without losing my data in 10.04

    thanks
    Karthik

    You'd have to upgrade twice. First to 10.10. Then upgrade to 11.04. There are potential problems you'll face:
    1. Wubi booting problems after upgrading to 10.10 (see post #1)
    2. General upgrade errors... some users have problems with upgrades for numerous reasons (hardware, software, custom config)
    3. Space issues. Upgrades require a certain amount of space and despite the upgrade process checking beforehand, some users have run out of space (so make sure you have plenty available).

    In general, it is advisable to backup your files (especially the \ubuntu\disks\root.disk and C:\wubildr) before upgrading.

    You might also consider moving to a regular dual boot. You won't be immune from upgrade issues, but it's generally more stable.

As far as i know the installer will chose the bit format appropriate for your machine and download extract and install. Try it this way and it should be fine.
    Greenbean,
    I try to install wubi on win7-64 but permission denied.
    Why?
    I download wubi from ubuntu official site.
