RE: Dell Precision 7510 TB16 Boot Issues

So I got the TB16 to use with my Windows 10 Precision 7510. I've had issues with the USB devices dropping out randomly but I seem to have got that under control (for now).

It might be if the devices are intermittent, they would exhibit problems during a Pre Boot Scan.

I wanted to boot from a USB DVD drive that was connected to the TB16. But when I tried to boot the laptop got stuck on the Dell logo and wouldn't go into POST.

You are wanting to boot a UEFI capable DVD, such as the Win 10 Install media, connected to the TB16?  If that is the case, I can test to see if I can do it.  I am wondering if the Thunderbolt is connected to the PCIe bus if any device there will be checked for boot compatibility.  

I suppose you can boot from that USB DVD when connected directly to your system?
