CentOS - Jan 2020 - CentOS 8 on USB disk

I did the dd if=CentOS-8.1.1911-x86_64-dvd1.iso of=/dev/sdd to a 16G USB
disk
then tried to use it on an install. The installer said invalid install
media.
Any way to verify if the "write" to disk was good ?  I got no errors
on the
dd.
I did re-download the iso and did a diff and there was no diff. So I think
my iso is OK.

Well after a closer look - Seems like the OLD 8.0 iso image is still on the
USB. Not the new 8.1

I have tried to redo the dd command to copy the 8.1 iso - I get no errors -
but it still comes up with the 8.0
I then tried to remove the partitions, save and recopy. still same old boot
menu.

Is there a trick to write over the UEFI stuff ?

What's your dd command?  Are you sure you are writing to the raw disk 
and not inside a partition?

Sorry for the noise... My machine must not be working. I copied the iso to
another machine, did the same command as always and worked just fine. not
sure what is up with my normal box. Has always worked before.
