Windows 8 BIOS questions

I am working with a Win8 Lenovo laptop, running into BIOS options I'm not familiar with.

1) On previous operating systems, in the boot startup section, I am accustomed to listing the CD drive as choice 1, and the hard drive as choice 2--and that's all.  But on this system it has the 'Windows Boot Manager' at the top of this list.  Do I need this included in the boot sequence?  If so, why do I need it?  What is it for?

2) I get the impression that the UEFI setting is designed to protect the operating system from threats.  But one time when I was trying to use an Acronis boot disk to recover a computer set for UEFI, it would not let me boot up on the Acronis disk, and I'm just guessing it is because Acronis is running on Linux on the boot disk.  (I think I read that somewhere, but I'm not sure.)

Anyway, it is safe and OK to routinely set the boot mode to Legacy rather than UEFI?

Leave things, BIOS, alone. All is okay, as it is.

Legacy is safe. But no need. Don't touch it. Don't repair what is not broken. Please. :-)

Since I am the person who has to service my customers, I need an understanding about these issues that I did not deal with previously in Win7.

So in regard to Windows Boot Manager, I still have these questions: Do I need this included in the boot sequence?  If so, why do I need it?  What is it for?

And having been set at UEFI DID appear to 'break' my ability to boot up a Linux recovery CD, so I need a better understanding about UEFI vs. legacy, please...something more in depth than 'don't touch it'.

Windows Boot Manager appears as the default in a UEFI BIOS.  You can still boot from Linux CD's if you press the button before Windows starts (after BIOS splashscreen) and select to boot from CD.

So, is there a compelling reason to leave Windows Boot Manager in the boot sequence?  Does it somehow benefit me?  Or, does it make sense to go back to the Win7 approach, where I would list only the CD and the hard drive?

And also looking back at the Win7 BIOS setup: Is there a compelling reason to have it set to UEFI, or is it fine to set it to Legacy?

It seems you are thinking that the BIOS options are a part of win8. That is not the case. So win8 has not introduced UEFI nor secure boot or anything. All the options that you see are BIOS/UEFI related and will be described in your computer mainboard manual.
