I'm trying to install ubuntu 17.10 onto a Dell Latitude E5580 from a usb stick onto which I've burned the 17.10 iso using gnome-disks. I've done exactly the same thing with the 16.04 iso and it worked fine (and still does). The problem is that when I hit F12 and boot options come up, the stick containing the 17.10 iso is not seen. When I do exactly the same thing with the usb stick containing the 16.04 iso, bios sees the stick under UEFI options, and I can boot to the stick. As far as I can tell the two sticks have the same structure. I've tried the same thing on two almost identical Dells, and the problem is the same on both. I've also loaded the 17.10 iso onto a different usb drive, with the same problem.

One difference that I do notice is that the 17.10 iso is on a usb3 drive while the 16.04 iso is on a usb2 drive. Could that possibly be the source of the problem, and if so, why? Isn't usb3 supposed to be better?

Here's the output of fdisk -l. sdb1 contains the 17.10 iso, and sdb2 contains the 16.04

When I mount the drive sdb1 containing the 17.10 iso, all of the ingredients for booting seem in place. Here's the content of the mount point:

Could somebody please suggest why my BIOS is not seeing the sdb1 drive?
