If it is an ntfs corruption issue, you can run chkdsk /r from windows on the drive containing the ubuntu installation and then try to boot again. You can access your data by booting from a linux live CD / USB, then mounting the appropriate windows partition, then mounting the /ubuntu/root.disk file therein using the -o loop mount option.
e.g. assuming your windows partition is /dev/sda1 (change it as appropriate): mkdir windowspartition mkdir wubi sudo mount /dev/sda1 windowspartition sudo mount -o loop windowspartition/ubuntu/disks/root.disk wubi #your files are now under the dir wubi ls wubi #to undo everything sudo umount wubi sudo umount windowspartition -- wubi install unusable - Buffer I/O error on device loop0 https://bugs.launchpad.net/bugs/204133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
