UEFI Build Test

[gold_finger]

Looks like you're doing everything correctly, so not sure what is going wrong.

One thing I can't tell from pics is whether you formatted the drive you're installing to as GPT or not.  It must be GPT for UEFI installs.  Enter this command and see what it says for the LL drive:

Code:

sudo parted --list | grep 'Table'

Report back with what is shows for BOTH the Windows and the LL drive please.

I can't remember if you said what type of machine you're installing to or not, but if it's a small tablet type system or maybe even some small netbook it's possible that you're dealing with a 32-bit UEFI instead of the much more common 64-bit UEFI.  If that's the case LL won't install.  It's pretty rare, but there are machines with a 32-bit UEFI and a 32-bit Windows install on them.  Best way to tell what you've got is to boot into Windows and open up system info section of control center (or whatever they call it).  It should tell you what type of Windows is installed.

If it's 32-bit Windows, then forget about trying to install LL -- it won't work.

If it's 64-bit Windows, then I'm not sure what is causing the problem (assuming the drive you're installing to is formatted as GPT).  Maybe try again and this time tick the box to format the LL EFI Boot partition.  (I noticed the box wasn't ticked in your prior screenshot.  Honestly I doubt that will solve it, but who knows?)
