Hello to everyone. I'm new to this forum (so sorry if I break the rules). I have Pegatron A15 modding work that I have unlocked and added Turkish language. I have unlocked it, but when booting Windows in UEFI format it freezes and when I shut down the PC sometimes HDD, USB and PXE disappear (only EFI Shell remains). Some are bricks. How can I solve this problem (Sorry for bad English. I translate with Google Translate)?

Thank you to everyone who has helped. :)

BIOS: AMI APTIO IV (4) UEFI BIOS
UEFI Specification: UEFI 2.0
UEFI Specification Architecture: AMD64 (x64)
BIOS Version: 303
