Well,  it's been a couple of years, but as best I recall, I had two
brand-new 1TB drives, intending to use them as RAID-1, and the BIOS was
(should have been, it said it was) in legacy mode. I thought it was
pretty weird that Anaconda wouldn't let me proceed beyond partitioning/
fs creation without setting up the EFI partition.

Somewhat more recently, I got a new system at work, containing Win10
(not a factory installation, but freshly installed by my employer
'cause they don't trust factory installation) and it already had
UEFI in legacy mode by the time I got it. so when I installed C-7
on it, I had none of that garbage about requiring the EFI partition,
it just sailed smoothly past it. 

Go Figure!
