[SOLVED] Can't boot into Arch after updating Windows 10

I'm dual-booting Archlinux and Windows 10 on my desktop, but after a lengthy update (weirdly enough Windows 10 decided to update on its own after I specifically set it to NOT do that), I'm no longer able to boot into my Arch install. The bootloader (systemd-boot) is still being run, but apparently the boot process tries to check  the "Windows Recovery Environment" partition with fsck and it fails with:

:: performing fsck on '/dev/sda3'
:: mounting '/dev/sda3' on real root
mount: /new_root: unknown filesystem type 'ntfs'
You are being dropped into an emergency shell.
sh: can't access tty; job control turned off
[rootfs ]#

I've been searching for a similar situation but found nothing. I've disabled Fast Startup on Windows and tried to update the bootloader with a live USB install (after chrooting into my install). I've confirmed that /dev/sda3 is indeed the Windows Recovery Partition. Can I safely delete it or reformat it?

@jasonwryan That is not the issue, the boot order hasn't change, the bootloader is doing its thing correctly.

@loqs Thank you, that showed me that the issue was indeed with the boot entry file, which was pointing the bootloader to /dev/sda3, which now is sda4 as the Windows update created thr Recovery Partition.
