I'd have to google what the acronym stands for but it's a utility in 
UEFI which allows 'legacy' booting, that is, booting via the MBR.

not sure what you mean: that's where some of the partitioning code 
used to lodge. I forget the details but something like BIOS jumps to 
code in the MBR which knows the partitioning scheme. UEFI, replacing 
BIOS, uses a different process. details cloudy. the crucial code is in 
a uefi-boot partition.

I don't like it defaulting to NetRunner since I wanted it to default 
to grub and then I could manage everything there. I'd like Windows, 
NetRunner (soon Maui?) and Trinity. I may remove NetRunner in the 
longer run but it's been fun and useful.
