Thanks, Gordon.  A lot of talk on Googleland talks about setting the 
BIOS to legacy mode, so that's the way I went.  Centos 7 said nothing 
the contrary either... or doesn't say much otherwise.  But so, yes, 
taking your advice: I reset all default BIOS settings to previously 
(UEFI enabled, Legacy disabled) and then accessing the flashdrive at the 
top of the list.

However now booting again, the CentOS 7 menu items all lead to these errors:

Image too small
error: /images/pxeboot/vmlinuz has invalid signature
error: you need to load the kernel first.

Press 'e' to edit the selected line,  or 'c' for a command prompt.

Any suggestions as to what to do here?
