However because the main partition has become RAW and corrupt, I cant re-allocate volume from there to create a new efi partition.(At least without formatting it). So far Ive tried to recreate a new efi partition for my OS drive through cmd in window installation media and boot from there. Everything in there has also become RAW and inaccessable. Through booting from window installation usb and another third-party recovery media, I found out that my DATA drive has become the new system Disk(with its own EFI partition) and relabelled itself as the new C drive, while the EFI partition in my OS drive disappear and combine itself with the main partition. I woke up only to see BSOD with winload.efi error everytime I tried to boot the thing up. After a power outage, my laptop suddenly decided to switch my OS(C:) drive and DATA(D:) drive overnight.
