I have a P70 and external Samsung T5 SSD. Currently, I have Window 10 pro installed on main HDD (Toshiba) T5 is connected to Thunderbolt/USB-C port (With USB-C to USB-C cable) (Windows see the drive) When I reboot and go to boot menu (F12) T5 SSD device does not show up.
If I connect T5 SSD (with USB-C to USB3.0 cable) the T5 device will show in the F12 boot menu.
I do not have an OS installed yet, I was just testing to see if/when the device shows up as option.
Is booting a device from Thunderbolt/USB-C port supported?
I found an older post saying no, but that was from 2016 with older BIOS. Is this supported in latest BIOS?

The answer still seems to be "no". I took a UEFI-formatted bootable usb-c thumb drive and it did not appear in a P70 boot menu. The same thumb drive can be used to boot an x1 yoga gen3

Does anyone know if Lenovo plans to support booting from USB-C port?
P70 has two USB 3.1 Type-C ports (Gen 2)
Samsung T5 SSD has one USB 3.1 type-C to C cable and one USB 3.1 type-C to A cable
(cables support USB 3.1 Gen 2) (According to Samsung packaging on box it shipped in)
When I tried T5 SSD with type-C to C cable, the drive did not show up in F12 boot menu.
When I tried T5 SSD with type-C to A cable, the drive showed up in F12 boot menu. I have not installed an OS
on the T5 yet. Using the type-C to A cable would have transfer speeds of USB 3.0?
It would be a nice option to be able to boot and have transfer speeds of USB 3.1
Seems this was brought up 2 years ago;
