I'll post this here in case someone has a solution that will be useful to me others.
Tried to get the live session of the new uEFI capable iso ( 9 April 2017 build ).
Always got to the grub menu, but the first couple efforts hanged - I let it sit for a minute or so just to see if it was slow, but no joy.
Finally went to completion, and auto logged into a live session, but the keyboard was dead (mouse worked) so I couldn't do anything.
This laptop - Toshiba 875D - isn't particularly user friendly when it comes to Linux uEFI - had some issues with Fedora and Ubuntu boot/live sessions as well so if you're shopping around might not be the one to get.
If someone knows a trick to get the keyboard going, please share the information in case someone else has the same issue.
Otherwise an excellent effort by Team VSIDO - (live session was smooth as silk on my non-uEFI machines)
