No bootable device for Windows 10 after update of Linux kernel 4.4.7 on Fedora 23

I have switched to Legacy Mode, disabled Fast Startup on Windows 10 before attempting installation of Fedora 23. The installation ran successfully, albeit with a network driver error unseen before, which gets fixed after replacing the original one with a newer driver.

Post-installation (at that time the keel is 4.4.6) I have rebooted twice with UEFI and Secure Boot enabled to ensure the Windows 10 continue to run properly. Booting into another OS requires me to change the boot mode in BIOS - Legacy for Linux, UEFI for Windows. The grub menu caot show Windows 10 in Legacy mode, and in UEFI mode my laptop automatically boot into Windows 10.

I left Windows untouched ever since. After updating the keel to 4.4.7, I found that I caot boot into Windows again. A "No bootable device" error pops up every time under UEFI, hence the Windows caot be booted in any way, though my Fedora 23 continue to run smoothly under Legacy. I am using Acer Aspire V15 with GPT partition table. I wonder if a re-installation of Windows would work; my personal data (/home) is stored in a separate partition than the Fedora system (/) and Windows. Please help. Thank you.
