ONE of my computers won't boot Ubuntu 19.04 (only) thumb drives

Hi, All:

Perhaps this SHOULD be a worry before Thursday's release. Please advise...

For years, I've used UNetBootIn to burn draft Ubuntu .iso files and test 
or install them on our computers at MMS, for our client Ubuntu users, 
and at our monthly FOSS User Group meetings in Natick, Massachusetts, USA.

That worked for draft desktop Ubuntu 19.04, too - until about two months 
ago. It still works on two of the three computers on which I test. But 
since SOMETHING changed, I get a black screen, or repeating attempts to 
read the thumb drive, on a Dell Inspiron 11-3157 netbook. (One of the 
working computers is a near-identical Dell 11-3147 netbook!) I can still 
boot and install successfully on the balky netbook, too, with Ubuntu 
earlier than 19.04 using the same thumb drive or any other.

Newer .iso downloads and burns don't help. Other burner programs 
(Startup Disk Creator, MultiWriter) don't help. Burning on a different 
computer doesn't help. Burning onto other thumb drives* doesn't help. 
(Although they ALL work on other computers.)

*- I've seen ONE exception. Less than two weeks ago, a friend burned the 
daily .iso using his current Fedora and its default burning app, and 
that thumb drive DID work on my netbook. (Sorry; I don't have it, and 
don't know which app.)

Any ideas? Might this affect other users out there?

Thanks, from
