To be safe, it is better to try with a bootable CD.
Question 1
What is your current boot method? UEFI boot or Legacy boot?
It's "Both" [UEFI first]
Question 2
In the bios, does the USB HDD appear in the list of bootable devices?
It appears properly identified as the correct disk model and size. In the case of a Leagacy external sata ssd the boot the Select-Alternative-Boot menu just bounces back. The net is FULL of simlar complaints but I have found no fix so far. Secure-Boot is disabled. I booted the Tumbleweed install DVD in a usb port of the laptop and installed TW to a sata ssd plugged into another usb port. Under booting I had grub2-EFI specified. This disk won't boot either in the T470, slows down the appearance of boot menus to 5 minutes for a menu to appear! When I eventually select the otherwise properly identified ssd the next step also takes forever but eventually the selection menu comes back on exactly as it does in the case of a Legacy disk above (except it takes MUCH longer). To be continued, I'm trading the T470 in for one with 1tb ssd (seeing that I may have to forget about just plugging a 2.5" sata ssd into a usb or thunderbolt port the same way that I can do with my entirely Linux desktop).
