How to boot Optiplex on a NTFS USB Key
Hi,
I open this post because there's something I don't understand in boot sequence of Dell Optilex.
I uses since months a USB Key wich is an extraction of a MDT Deployment Share. We use it to deploy computers that are out of our network. This key is formatted in NTFS because my iso file is bigger than 4 Gb. It has been made with unetbootin.
On Dell Laptops like Latitude, when I hit F12, I have an option UEFI Boot --> Kingston...... which allow me to start and install my image.
On Optiplex (tested on 3010 and 9020), I do not have this option. If I tried boot USB with Legacy, it does not work (not bootable error message). If I tried UEFI, USB key does not appear.
I've updated the BIOS without success
Is someone can help me with this issue ?
Thanks,
Christian.

Secure Boot Disabled
Legacy Bios Enabled
Legacy Boot Enabled.
F12 F12 F12 ...... 42 times if the usb flash was inserted BEFORE Turning on it should see it.

I verified the following points :
Secure Boot Section : Disabled
Boot Sequence/Boot List Option Section : Legacy
Advanced Boot Option section : Legacy Option Rom Enabled
USB Configuration Section : Enable Boot Support enabled
Hitting F12 sevral times, no UEFI Boot --> "My USB Key" option. Only USB Storage Device in Legacy Boot which does not work(selected boot device failed)
Also trying UEFI Boot Option without secure boot. Same thing, no UEFI Boot option for my USB key.
I've compared each screen between Latitude where it's working and my Optiplex. All options are the sames but the behaviour is not.
