Windows is booting and functioning as well as Windows can. (Tongue in 
cheek, but no problems have developed recently, and I am sending these 
messages from the Windows installation on the problem machine.) The 
normal Linux boot process was to see the Windows boot menu, select the 
Linux installation, hit Enter, then see the GRUB splash screen with the 
countdown timer, which then booted the most recently installed kernel by 
default. (Which I've seen as normal.) But, what I'm seeing currently on 
the machine is just after selecting the Linux installation and pressing 
Enter, are just a black screen, with white text, stating simply "GRUB" 
in the upper left corner. I wouldn't exactly call it a prompt as there 
is no indication that it's waiting for any input, and nothing appears 
when I type. Doing the three fingered salute (control-alt-delete) has no 
effect, and in order to get the machine to do anything again, you either 
have to hit the reset button or toggle the power. Well, I take that 
back, I can play with scroll lock, num lock, and caps lock lights via 
their respective keys. :-)

Thanks Jacques,
