1. It states to change the BIOS setting to UEFI BIOS mode prior to installing. Although the disk will install windows 10, without changing the BIOS mode. The following Windows 10 Pro functions will not work.
* Secure Boot
* Seamless Boot Experience
* Network unlock for Bitlocker for systems Trusted Platform Module (TPM)
* eDrive support
I did the F2 key thing to get to the BIOS. Changed the CSM Boot to UEFI Boot, hit ESC. It then instructs to select Security -> Secure Boot and
then Enabled. To save change and exit BIOS setup, press F10.
I was able to do the switch to UEFI Boot, but there is not a selection to Enable it. ...

Question; if I leave the enabled part of it out, will it be OK to install the Windows 10? Not certain if the any above listed items is important or not, but figured I'd try and do it right.
2. When ready to install Windows 10:
* Instruction states to Make Sure Your Computer is turned OFF.
* Press hold the F12 key, and then turn on the computer to start the Boot Menu.
* Load Windows 10 Pro Recovery Media in the optical disc drive.
* Select ODD in the Boot Menu.
* Follow the on-screen instrcutions to complete the set up.
Question; After completing the install. Do I have to change the Boot Menu to whatever it was origionally?
Thanks in advance for the help!
