Yes, exactly.

Unfortunately, it's GPT under EFI. I can access all my files through the 
F12 key on this Dell tower, be it Windows, Linux or FreeBSD, but if I 
allow it to boot with the Doze HDD in the system, it boots to that one.

I appreciate the good data, Manish. I'm going to make sure I've gotten 
all my files off the Doze partition and then wipe it completely. FreeBSD 
is going to be my primary host OS and I'll keep my other drive for 
whatever flavors of Linux I need to work with for work. Based on what 
I've hseen on these threads, MS is still saddled with a number of bad 
legacy architectural choices as well as poor management choices, and 
both of those contribute to the challenges the use of their OS brings.

I simply won't accept any contract that requires me to work with 
Windows. I've survived well enough without that skill set and I see no 
problem going forward.
