While widely discussed, you pick a mode and stick with it.

Changing this mode can cause issues. It is not a problem by design. That is, I expect such but without writing a book on UEFI... Plenty on the web so keeping it short. Expected.

what operating system
Apr 17, 2015 7:02AM PDT

do you want to use? If it's not W8 or W10, you can just leave in Legacy mode, even for 64 bit software. There's no requirement I know in windows or linux forcing use of UEFI unless it's on an OEM system. I've loaded EFI capable Linux versions on standard BIOS type motherboards (same as Legacy) and not had any problem doing it nor using it.

The next thing to think on is the type of Partitioning on the hard drive is used. Is it MBR or GPT?

The shortest tutorial on this.

1. Wipe the drive clean.
2. Set the bios mode you want.
3. Boot the OS DVD.

If the OS doesn't support, UEFI, pain.

their UEFI BIOS requires them to enter drives as boot in 2 places. Also the "protective MBR" may have been corrupted and if so then you need to get the program "gdisk" and fix that, or use the software the drive manufacturer has to create a blank GPT setup on the drive.

It's Microsoft and Intel that's dumped this UEFI on us, so I'll let the Intel guy try to confuse you more. If he says the word "simple", shoot him.
