To play the game, Secure Boot needs to be enabled in the BIOS settings. However, my system drive uses the MBR partition style, and turning on Secure Boot will result in a boot failure（BTW, many people enable Secure Boot directly without checking their partition scheme first, only to end up with their PCs failing to boot.） This means I’d have to reinstall my system just to play EA games. Forget it, I’m not worthy of the premium Battlefield series.

at very first check if you run a HDD or some older hardware 'settings', be sure to switch your Disk formation from
MBR into GPT
.. then:
update BIOS/UEFI to 'latest' Firmware (highest priority, always)
in BIOS/UEFI switch 'Legacy/CSM' to 'UEFI'
create fresh factory default keys (Key Management), depends on BIOS manufacturer
enable 'Secure Boot'
reboot your machine, and wait
update your OS afterwards to scan/check/fix possible (compatibility) issues
verify gamefiles
