[GTALUG] Making a UEFI capable debian USB net-install

[Michael Galea]

Just completed an install of debian on a Lenovo T480 running windows, 
for dual boot.
The install was made more complex by the fact that the T480 doesn't have 
a CD, and that the laptop booted win10 in UEFI with secure boot.

I was very surprised by the differing consensus of how to generate a 
UEFI bootable net-install. A simple dd of the image to the usb stick did 
NOT result in a UEFI bootable image. What did work, was formatting the 
usb stick vfat, and extracting the install iso onto it.

I found this to be a clumsy workaround. Does anybody have a better method?

Also, the literature was rife with warnings of Window's tendency to blow 
away the the linux bootloader (although some claims were made that this 
is less likely under UEFI). Does anyone have any experience with this, 
and what what is a likely recovery procedure for it?
