If your manufacturer is not listed below, you can use the common terms in the next section. Use the guides below depending on your manufacturer to get you started. You will need to access your system’s BIOS menu so that you can disable CSM on your system. Disabling CSM will allow you to enable UEFI on your system which is needed to install the most modern compatible Operating Systems.

Hence, CSM helps emulate a BIOS environment that is compatible with your current OS. UEFI is fairly new and in case you have CSM on your system you are likely using a legacy OS currently unsupported by your UEFI system.

Unlike the errata which says "intermittent booting problems", my issue is consistently reproduced with no other result no matter what I do.
