Imaging Latitude 7290 (what is legacy external and how do I avoid it)
I am testing the Latitude 7290. I usually switch from UEFI to legacy. Now legacy is external only. I am at a loss. I finally got it to image through lots of trial and error but now it only tries to boot to the network and not to the hard drive. When I go into BIOS I have 3 choices. UEFI no secure UEFI secure and Legacy External. None of which show the hard drive as a bootable device. Thoughts and ideas are welcome. My supervisor believes this to be a driver issue. I think it's a BIOS issue. Help!
Also how long does it usually take for the drivers of new models to show up in the Driver feed?

1. you are right with the driver issue.
You need to build a new KBE with the right driver:
Download the hdd driver from Dell, unzip it and add it to \\SDA\drivers\kbe_windows_x64, recache the drivers and as soon as it is done create a new KBE.
2. the drivers for new models are avaiable as soon as they are staged, this means, if Dell provides the driver pack it will be made avaiable for all appliances which are in support. This is a midlevel driver injection so it does not allow you to boot a kbe to a system when the kbe has not the right drivers in it (I hope there will be a future solution to inject the nessesary drivers automaticly to ta prebuilt KBE, but right now you need to build it by yourself)

Hi, thank you for your response, but to be honest it did not really knew how to do what you did.
I found out in the BIOS there is an option under System Configuration -> Integrated NIC : Enable UEFI Network Stack.
So i enabled it, captured a new image and boot the machine -> booted to the onboard nic, uploaded it and able to deploy that image without issue.
I guess they have changed things....but really took me so many tries before finding this fix!

I don't have it, but looking at it's manual, I don't see it listed.
See:

VS.

I would discard the drivers, 100% not the issue...
Maybe try a dummy UEFI Imaging and confirm this is either a BIOS\Compatibility issue.
Contact the manufacturer to clarify what exactly is Legacy External.... I don't recall seeing that before. - Channeler 6 years ago
Did you ever resolve this issue?
I have the same problem with same Dell machine 7290
Captured the image, deployed it and no bootable devices found.....
Can you please help?

1. Create a new Post-Installation Task
a. Type: BAT Script
b. Name: UEFI Legacy Conversion
c. Runtime: SDA Boot Environment (Windows)
d. BAT Script: (Use the following)
bcdboot c:\windows /s s: /f UEFI
bcdedit /store S:\efi\microsoft\boot\bcd /set {bootmgr} device partition=s:
bcdedit /store S:\efi\microsoft\boot\bcd /set {memdiag} device partition=s:
bcdedit /store S:\efi\microsoft\boot\bcd /set {default} device partition=c:
bcdedit /store S:\efi\microsoft\boot\bcd /set {default} osdevice partition=c:
Bcdedit /store S:\efi\microsoft\boot\bcd /set {FWbootmgr} displayorder {Bootmgr} /addfirst
bootsect /nt60 s:
2. Duplicate your existing Single partition image
3. Remove the existing Legacy Preinstallation tasks (Single Partition, Format C, MBR)
4. Add the Create UEFI Partitions (built in) at the Preinstallation section
5. Add the UEFI Legacy Conversion task (created above) at the Mid-Level Section
6. Save
7. Deploy
8. Profit!
Please feel free to let me know if you have any other question - keri.saxowsky 5 years ago
After you capture the image, then you can boot into the Onboard nic, download the image and it till work. - yche 5 years ago
