I went into the laptop BIOS, got brave, and un-checked PTT in the security section. BINGO!
I knew there was an issue with the BIOS 'handing off' to (any) operating system because, after the Dell Logo - it 'hung' unless I pressed either [F2} Setup or [F12] Boot Menu before the logo timed out.
Now, all three O.S.s (Win 10, RHEL 8, Debian 12) show up in grub and boot normally. 'Happy Guy'!
[I didn't really want to wipe RHEL 8 and re-install if I didn't have to - it wouldn't have helped anyway, now that I know this!]
