    Problems dual boot, Help!!

    I have read already few threads related to my problem, but no one was sufficient to solve it.

    I had windows 7 in my laptop and I decided to install Ubuntu 11.04.

    During the installation I split a big partition of 400gb (which only 100gb used by windows) in 2gb swap and 100gb ext4 for ubuntu. However, the 400gb partition that initially was labeled as 'type' 'ntfs', now doesn't have any type and under the field 'Used' there is written 'unknown'.

    There was no way to go back to the previous state and I completed the installation. Since that I haven't been able to boot Windows 7 anymore. In the GNU GRUB, besides the Ubuntu lines, I have 2 new options:
    Winfows Recovery Environment (loader) (on /dev/sda1)
    Windows 7 (loader) (on /dev/sda2)

    where the command for booting the second one is:
    Code:
    setparams 'Windows 7 (loader) (on /dev/sda2)'
    
    insmod part_msdos
    insmod ntfs
    set root='(/dev/sda,msdos2)'
    search --no-floppy --fs-uuid --set=root 9A .... 4B
    chainloader + 1
    and if I try to boot it the windows boot manager says: 'Windows failed to start. .... The boot selection failed because a required device is inaccessible'

    Moreover, if I try to boot Winfows Recovery Environment (loader) (on /dev/sda1) it ends up in Acer eRecovery Management where I can only completely restore system to factory defaults (where all C: drive will be deleted). The other options are not available!!!

    The situation of my disk is the following:
    Code:
    Disk /dev/sda: 500.1 GB, 500107862016 bytes
    255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes

    /dev/sda6       226691072   976771071   375040000   83  Linux
    Please help me!!! I really need to have windows back without loosing any file, and very soon (I need to finish my thesis).

    Thank you so much,
    Davide

    ps. Ubuntu is running properly and I will not have my windows cd for the next 3-4 weeks.

    /dev/sda1 2048 27265023 13631488 27 Unknown -----> Gone wrong??

    It seems your main Windows 7 ntfs partition has gone wrong, unfortunately that can happen when resizing.

    In future I recommend backing up important files before you proceed with such an operation.

    You can safely try a program called testdisk to make an assessment on the unknown partition although the outcome is not a definitive answer as to the recoverability of the partition.

    sudo apt-get install testdisk
    sudo testdisk

    Quick steps

    1. no log
    2. select your disk
    3. Intel / PC Partition
    4. Analyse
    5. Do a 'Quick search' on the unknown partition

    If a quick search fails you could try a deeper search.

    What does test disk report on the unknown partition?

    ok! I am running it now, but it seems a bit slow. I will write here the results as soon as it finishes.

    Anyway... Do you think I will be able to recover my data?

    Thanks

    Re: Problems dual boot, Help!!

    If all else fails, boot a live linux CD, hook up an external USB drive (if you have one) and copy the pertinent data to it. Then do a windows 7 system recovery, and put it "back to factory defaults".

    At least you'll have your data to put back in.

    Just backup your C:\Users folder, and any others off of root which are important. Check your C:\Program Files for any other applications and potential data first.

    How can a live linux CD access the data that was in windows? And what should I actually do? I can run ubuntu, but I can't mount that partition!

    Thanks

    a live cd runs form the cd so there will be no hard drive mounted so u can mount and extracct to a usb

    The OP's NTFS partition is being registered as unknown, Ubuntu cannot therefore mount it.

    Waiting for the testDisk I run the boot Info Script and this is the result:

    Re: Problems dual boot, Help!!

    Code:

    If /dev/sda1 is your recovery partition, then I think you should stop the test disk analysis.

    /dev/sda2 = the 100MB Windows 7 partition

    The rest are your Linux partitions.

    Are you sure you resized your windows partition? It looks more like it was deleted.

    EDIT: Infact Looking at the partition file sizes using your fdisk output, with sda1 at about 13GB is certainly does look like a recovery partition. I apologize for sending you on a wild goose chase.

    Yes I did, or at least I though!!
    What should I do now to recover the data and run Windows?

    Thank you so much for your time.
