Here’s a side tip for those Latitude 10’s… the dock can only support two USB devices at a time. This machine SUCKS.
I’ve also seen that in my case anyway, the only USB port that sees a USB device (pre-windows) is the front dock USB. So, how do you put the keyboard in the front USB to boot to the BIOS, and choose the flash drive (which also has to be in the front port)??? Well, to free up a USB port, pressing the Volume UP button on the side of the tablet, and I mean pressing it rapidly non-stop, is the same as hitting F12 on your keyboard. That’ll get you to BIOS and you can then see your flash drive which is in the front port. All this, providing that its a working bootable flash drive. As I’ve said, my OS boots up fine through the flash, but not Clonezilla. Hope this helps.

For those of you with Dell Latitude 10 (ST2 or ST2E) tablets… Dell has verified over and over that this model will NOT boot to PXE. Their tech team will not modify it to boot to PXE. The next model coming out will be able to. Had a Dell Slate do the same thing…three bios updates later, it would boot to PXE. These will NOT. They are not going to modify them to be able to. I’ve been trying to Clonezilla these $(%*&@# and yes they do freeze at the GRUB screen. I’ve been able to create a bootable USB drive to install my OS so that all works…I think its to do with the x86 32bit architecture that’s causing Clonez problems. I will be speaking with a “level III” tech today to get more info on capturing this image. For now, I am NOT going to set up a server with Server 2012 and MDT just for hits model to boot. I’ll post more replies as I get them.
