    I am having an issue with the deploying an image on a Toshiba laptop it seems to corrupt my image

    image store corrupt unable to locate mbr

    I have able to deploy successfully this image to other machines prior this one but now getting this message. When I look at the image on the fog server it now says 0.0 bytes but before this error started, it said 149.5 GB


    Now When I try to deploy this image on a different machine other the Toshiba it works just fine…, And now the image does not say 0.0 bytes but now back to the original image.

    @cnkpadobi well that is sure one way to fix the issue!! Thank you for the clarity.

  • @george1421 Pull the 500GB out of the computer

    @cnkpadobi So how did you resolve this?

  • Got this resolved… Thank you

    No did not know it had to 2 disks on one show up in the UEFI bios… which is the SSD 256. My image does not have multi-disk but just has two partition.

    @cnkpadobi Well… This is an interesting device you have there…

    According to lsblk that device has 3 hard drives. Well 2 and the flash drive.

    /dev/sda = 250GB disk
    /dev/sdb = 16GB disk (flash drive)
    /dev/sdc = 500GB disk

    Is it safe to assume this is your intent to have a computer with 2 physical hard drives?

    Does your image contain multiple disks?

    @cnkpadobi Its possible if the toshiba sees the flash drive as a hard drive.

    One way to get an answer is to setup a debug deploy. Just do a normal deployment to that computer but before you schedule the job select the debug check box, then pxe boot the target computer…

    Wait you are using a usb drive to boot FOS. Do you have a menu item #6 it was like a debug boot? If you do select that and that will drop you to a command prompt on the target computer. Once at a command prompt key in df -h and lsblk and post the results here. That will tell what FOS thinks its seeing for local storage.

  • Hmmm so how would it point to the d2.mbr instead of the d1. I am deploying it now on the new machine… Would that have something to do with the flash drive fos?

    The thing that sticks out here, is that FOG is trying to deploy to disk 2 (d2) instead of disk 1.
