    Can I boot into Wubi or at least recover Wubi files when root.disk is 0kb in size?

    I installed Wubi two months ago for an internship. It worked great all summer, but roughly a week ago I could no longer boot into Ubuntu. I get the GRUB screen.

    I've followed countless instructions on the web. I've run dskchk, I've tried using "ext2read" type software, I've tried running GRUB commands, etc. Nothing so far has worked (if you want specifics about how none of them worked, just ask). Today though I noticed something...

    My root.disk file is 0kb in size!

    It never occurred to me to check the size until I kept reading the same story about it over and over again. However, to my horror, no one seems to have explained how to fix it.

    So, is there a way to boot into Wubi again if root.disk is 0kb? If not, how could I go about recovering my files? The files I want to recover are nearly all ".cpp" or ".txt" files.

    IF the root.disk file is indeed empty, there is (1) nothing to boot into and (2) nothing to recover. Sorry ...

    I can't accept this as an answer. My entire Ubuntu hard drive couldn't have simply been wiped!

    Two questions (for anyone and everyone):
    Is root.disk the entire Ubuntu partition?

    Might the missing files show up in a hard drive recovery tool like photorec?

    Is it really DEAD dead? Are all my Ubuntu Wubi files that I spent a summer working on completely wiped from hard drive? Is there no recovery that will find them?

    If so, say so!

    root.disk isn't a partition, it's a file within your Windows partition.

    YES -- it's a file that acts like a Linux filesystem.

    Don't know for sure -- but probably not, as it is not a native Linux filesystem.

    Where was your root.disk stored? If your win7 and kept it in your Documents you might be able to use shadow copies

    Re: Can I boot into Wubi or at least recover Wubi files when root.disk is 0kb in size

    The root disk is installed on the c drive by default . To most Windows (defrag) disk tools the root disk is seen as series of clusters. There may be some third party applications that could affect, harm, or remove the root disk.

    I know a few Wubi users (Win7) and have never heard of the disk volume being reduced or removed without Wubi being removed and in that case there would be no Ubuntu option in the windows boot loader. Windows 7 system tools can identify Ubuntu as an unknown operating system.

    My root.disk file is 0kb in size!
    How did you verify this ? If this is the case I would be inclined to agree with Marks first response to the thread. If the root disk is 0kb it is not ok so knowing how that was determined may be important .

    Re: Can I boot into Wubi or at least recover Wubi files when root.disk is 0kb in size

    When I open My Computer in Windows 7 and navigate to C:\ubuntu\disks, it lists root.disk as being 0kb in size. Also, if I open root.disk in a text editor, it's basically a blank file.

    Could this information be inaccurate though?

    After checking with a Wubi user I found that you should see a volume thousands of Kb under C:\ubuntu\disks and in his system there is a swap volume as well. The root disk is definitely gone. I don't know if a recovery tool is an option with a Wubi installation or not.
