    Here's what you missed. Windows Boot Manager has nothing to do with booting the CD/DVD. It only uses to boot the HD/SSD containing Windows. For example: If you have 2 Windows Installed on 2 separate HD/SSD, You'd have 2 Windows Boot Managers listed in the BIOS and you must set the correct boot order of "Windows Boot Manager" to boot into the version that you want. Here's the screen shots:

    Boot order is set to: UEFI CD/DVD: UEFI-TssTCorp....... tells BIOS to look for CD/DVD First and boot mode is UEFI.

    Boot Priority is also set to: UEFI CD/DVD: UEFI-TssTCorp .... Tells BIOS to boot from this CD/DVD
    NOTE: There's only one CD/DVD in my PC so there's only one entry. But if I have multiple CD/DVD's then I have to select which CD/DVD to boot from

    Thanks for your response but yes I am already aware that the Windows Boot Manager simply boots the PC into Windows. If I access the F/W without inserting any disk, the options I have are in the following order - 1. Windows Boot Manager; 2. P5: <DVD Drive>; 3. P0: <System Drive>. If I swap 1 and 2 around and try booting I am told to insert a bootable media and reboot. If I now insert Kyhi's disk the following is the boot order I get - 1. Windows Boot Manager; 2. UEFI: <DVD Drive>; 3. <DVD Drive>; 4. P0: <System Disk>.

    To get Kyhi's disk booting up, I have to move 3. to position 1. This moves WBM to position 2. and UEFI: <DVD Drive> to position 3. One other thing you should also know is that when I want to boot from a CD or DVD it looks like I have to check the sequence every time otherwise I'm likely to get a result I don't want. What I DO know is that Kyhi's disk works fine if I set the sequence such that <DVD Drive> appears first in the list. If UEFI: <DVD Drive> appears first in the list the disk is ignored and the PC boots into Windows 10.

    I'm beginning to think I may have made a bum buy with this mobo but I'm stuck with it now. Anyway, I hope what I've said above makes sense as it is a bit awkward to describe particularly since I don't have any means of capturing a screen shot of my F/W.
