Dear all,

I am using Microsoft MDT to image computers, i have created a media resulting in an ISO file. I have burned the ISO to the USB stick using rufus http://rufus.akeo.ie/

I can install my image on all the laptops i have tested Latitude E4300, E4310, E6230, E6320, E5400

When i try with an Optiplex 7010 (USB boot is enabled in the bios, Bios is version A12), the USB stick looks like it's not detected at all, no errors, it just boots straight to disk even if i tell the boot sequence to boot to USB.

The USB key is formatted using NTFS and the Optiplex is set to BIOS Legacy mode.

Any ideas what my problem is?
