MDT 8450 No Bootable Device Found Dell Precision 5530

    Question

  • Hello, 

    MDT Version: 8450

    System being imaged: Dell Mobile Precision 5530

    I am running in to an issue where after the install Operating System phase, on first reboot the system is throwing a no bootable device found error.  BIOS and boot options do not display Windows Boot Manager.  I found the following Dell article, but this is in reference to an older version of MDT and the line to be replaced does not exist on my server.

    Boot Manager Not Found On First Reboot After MDT Install Using UEFI

    When I run the deployment on my VMware test VM, it runs all the way through without any errors at all.  I believe it has something to do with the UEFI BIOS as described in the article, as the VM is using legacy BIOS and has no issues, I just don't know where to start troubleshooting.

    Thanks in advance,

    Zak

  • Check your task sequence and make sure you are formatting the drive for UEFI to match the BIOS settings.

  • Should I disable the "Format and Partition Disk (BIOS)" step?  Both the BIOS and UEFI format options are enabled currently.  Unfortunately, this is a remote site and I won't be able to test until Monday when I have a tech on site to test the deployment.  I will follow up then.

  • Yes, I would disable that especially if its running after the UEFI formatting. And if you are only using this task sequence for UEFI its not needed.

  • Disabling the "BIOS" format and partition option didn't seem to make any difference.  It's still rebooting back to a no bootable device screen.

  • I would check the BIOS of the computer you are imaging and see what the boot options have been set to. If it is set to UEFI I would change them over to legacy and see if the system boots.

  • Try setting Secure Boot to Disabled in the BIOS (leave the boot mode as UEFI).

    We've been imaging some Precision 5530s recently and found that this worked.

    Cheers

  • Disabling the disk format task won't make the difference.

    If you look at the options on each of the disk format tasks, you'll see they each depend on the isUEFI property that gets set during Gather.

    > BIOS format task only runs if isUEFI = False

    > UEFI format task only runs if isUEFI = True

    Look in your bdd.log file and search for isUEFI to see if the property is being set correctly. Modify your UEFI/BIOS settings to get isUEFI property set as you want
