Bootcamp disk not bootable

I was trying to non-destructively expand my bootcamp partition. I began by shrinking my macOS partition using Disk Utility. This automatically created a partition in the remaining space called "Untitled."

When I rebooted after that (holding Option), the Bootcamp partition no longer appears as it used to. I tried resetting NVRAM, which resulted in no change.

In Disk Utility, when I select "get info" on the Bootcamp partition, under "Bootable" it says "no." I have also since deleted the Untitled partition and given the space back to my macOS partition.

How can I boot back into Windows? Continue trying to expand the partition? Please help.

The extra partition creation causes problems with the MBR on used on 2012 and older Macs. If you can see the files, that is good sign.

Can you install GPT Fdisk? Your situation is similar to windows 7 wont statrt - Apple Community.

It’s a MacBook Pro 13 inch, Mid 2012 running macOS Mojave and Windows 10. Both are fairly up to date but I can post exact version numbers later if you need them.

Yes, I can see the Windows files.

Something to add, I tried to select the Bootcamp disk as default and reboot through System Preferences > Select Boot Disk. On reboot, I see “no bootable disk found — insert disk and press any key”.
