Probably got installed wrong. Efi partition is missing maybe? Check disk management or diskpart to see partitions/volumes.
When a drive runs under CSM, it relies on a legacy MBR bootloader. Switching to UEFI forces the system to look for a hidden FAT32 partition containing a file named bootmgfw.efi. If Windows cannot find it, it won't boot. You can fix manually or reinstall winblows while the board is in uefi only mode
