Windows 10 won't boot from grub

I currently have Linux Mint installed along Windows 10, and both have been working harmoniously together for a good 6 months. This morning, I attempted to select Windows 10 from the grub menu as I do every morning, and was greeted with the error

/EndEntire
file path: /ACPI(a0341d0,0)/PCI...
error: cannot load image

Press any key to continue...

Apparently one of the most common causes of this error is not having secure boot disabled; however I'd already encountered this program the first time I installed Linux and hence secure boot is still disabled. boot-repair has also been suggested, so I installed and ran that. After running boot-repair, my grub options had expanded to

Linux Min 18 Cinnamon 64-bit
Advanced options for Linux Mint 18 Cinnamon 64-bit
Windows UEFI bootmgfw.efi
Windows Boot UEFI loader
EFI/ubuntu/fwupx64.efi
EFI/ubuntu/mmx64.efi
Windows Boot Manager (on /dev/nvme0n1p2)
System Setup

Selecting either Windows UEFI bootmgfw.efi or Windows Boot Manager yielded the same error as before. However, selecting Windows Boot UEFI loader resulted in a BSOD-like screen along the lines of

Recovery
Your PC/Device needs to be repaired
There is an invalid object in the Boot Configuration Data store
Error code 0xc0000034

I'm hesitant to proceed with further troubleshooting on my own as i'm rapidly getting out of my depth and don't want to make things worse. Do i need do something along the lines of running bcdboot from a Windows Live CD, or is this a problem with grub?

For historical purposes, I thought i'd mention I bit the bullet and ran

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

from a Windows install medium. This did the trick - Windows now boots via Windows Boot UEFI loader in grub (grub itself was not corrupted at all).
