How to disable UEFI ??

[Brian Cluff]

Same here.  I find UEFI to be superior to BIOS, but secure boot, can be 
problematic, but mostly because of who has to sign the boot loaders.

Most people that I have run into actually just have a beef with not 
having the familiar MBR style of booting, but that just comes from a 
lack of experience with proper UEFI boot experience, and not realizing 
that the way UEFI boots things is completely different to the way BIOS 
boots things... like not realizing that you are required to have a EFI 
partition on your drive.  Most of the time that I've seen an unbootable 
UEFI system is because the whole system was partitioned without that 
necessary partition, so the system will be fully installed, just without 
any way to be booted.

Once I wrapped my head around the way UEFI boots systems I found it to 
be a much better system than the old MBR method that tends to only allow 
the last system to load to actually boot... especially if that last 
system is windows.
