    Question Copy bootable CF and convert to vdi

    Hi

    I have been struggling with this all night.
    if I use
    dd if=/dev/sda1 of=/home/wizball/Desktop/access1/convert/cf.image

    to copy the CF it just copies the files it seems and does nto make a boot able vdi afterwards.

    If I use
    dd if=/dev/sda of=/home/wizball/Desktop/access1/convert/cf-card.img

    after mounting the cf to sda1 then it copies the cf and see,s to go on to the hard drive that is also mounted there.

    I have looked around the Internet for solution but cannot find one.

    I have managed to convert the image that is produced using
    VBoxManage convertdd cf.image cf.vdi --format VDI

    but it will not boot.

    I am connecting the CF card to the computer via usb.

    many thanks in advance
    Peter

    Hi Peter,

    You are trying to create an image of a CF and then convert it to vdi format.

    First step will be the copy. You do not need any virtual machine for this step. I suppose you have a physical computer running Ubuntu.

    You have to be sure that the CF device is not mounted (umount it if necessary). I will suppose that CF device is /dev/sdc. Then you have to type this command:

    Code:
    sudo dd if=/dev/sdc of=CF.image.dd
    You have to use a virtual machine with Ubuntu or other Linux distro for the second step.

    Define an additional virtual disk (.vdi) with just the same size of CF. Do not initialize it. I will suppose that the device assigned to this new virtual disk will be /dev/sdb.

    Copy the file CF.image.dd to a folder of the virtual machine and go to that folder.

    Then type this command:

    Code:
    sudo dd if=CF.image.dd of=/dev/sdb
    Shutdown the virtual machine.

    The file vdi will contain the image of the CF converted to vdi format.

    An alternative for step 2 (raw disk image to vdi conversion) would be to use the VirtualBox tools:

    Use this command if you wish to list the drives detected by the system:

    Code:
    sudo fdisk -l

    that is great thanks the the first part was a lot longer then I had seen before according to that command but seems to have worked.
