Weird iMac error - stuck in Windows

[boxst]

I have a 2016 iMac 27” which was working fine. It has MacOS and a bootcamp partition with Windows 10.

Yesterday it started booting into Windows only. No apple logo, just windows. Bootcamp doesn’t think there is a Mac partition, file manager just sees the windows disk.

None of the normal key combination on boot work (recovery, drive selection, well anything). And what throws me is that even the ping and apple logo doesn’t appear.

Having scanned the internet it is a bit more common than I would have thought but no answers.

Any help appreciated.

By 'Recovery' you're referring to Safe Mode?

ETA Could you create a recovery stick from another Mac somewhere and try directly booting from that. See if you can get in to the preferences to see what the Startup order is maybe.

Booting the Mac with Command R.

Thank you for the replies. After a frustrating day and morning - fixed it.

I have no idea what caused it, but I plugged in a windows usb keyboard, restarted holding windows/alt P R (i.e. reset the NVRAM) and it booted.

Previously I tried different a wireless keyboard, wired (with a lightning cable) and it didn't work. So just one of those things.
