    restoring grub after a "successful" hd clone

    I used GParted Live CD to clone my hard drive to a larger one, keeping the dual boot partition structure intact. This is the GParted view of the new hd after cloning, identical to the old one except for amount of free space:



    And here is the output from fdisk:

    Code:
    user@debian:/$ sudo fdisk -l
    
    Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
    255 heads, 63 sectors/track, 121601 cylinders

    Little did I know that the apparently seamless cloning operation would wipe out grub and prevent me from booting as on the old hd. The problem now is that I can't restore grub 0.97. For starters, I can't boot into Windows or Linux regardless of which partition above has the boot flag. (In that picture the Windows partition has the boot flag.) Next, I tried a standard recovery of grub. When I run grub from the GParted Live CD command line, I get this:

    Code:
    grub> find /boot/grub/stage1
    
    Error 15: File not found
    
    grub> find /grub/stage1
    
    Error 15: File not found
    
    grub> root (hd0, 4)
    
    Error 11: Unrecognized device string
    
    grub> root (hd0, 0)
    
    Error 11: Unrecognized device string
    The Linux partition definitely has /boot/grub/stage1 on it and that partition on /dev/sda should be referred to in grub as (hd0,4) right? What is going on and what can I do to fix it? I've seen related issues discussed but never this exact problem plus a solution. Thanks for any help~

    Re: restoring grub after a "successful" hd clone

    Are you sure you still have grub legacy & not grub2? You do not have both old & new drives mounted do you. Identical UUIDs will cause confusion.

    OK, thanks for the quick reply. Yes it is grub legacy and only the new drive was connected. Here is my results.txt file:

    Re: restoring grub after a "successful" hd clone

    Boot the ubuntu Live CD/USB. Choose "try ubuntu". When the desktop loads open a terminal and do this:

    Code:
    1. Type sudo grub. Should get text of which last line is grub>
    2. Type "find /boot/grub/stage1". You'll get a response like "(hd0,4)". 
       Use whatever your computer spits out for the following lines.
    3. Type "root (hd0,4)", 
    4. Type "setup (hd0)", to install GRUB to MBR
    5. Quit grub by typing "quit".
    6. Reboot and remove the bootable CD.

    Re: restoring grub after a "successful" hd clone

    Thanks, worked like a charm. That's exactly what I did at first, except I was using the GParted Live CD. In case anyone comes across this thread, here's the lesson: don't use the GParted Live CD to restore grub, use a regular Ubuntu live cd!
