This happened to me on a Z790 Hero and Z890 Apex when the Windows 11 boot partition became corrupted.  This began happening after the Windows 11 24H2 update and continued off and on until I did a clean reinstall of Windows 11 24H2.  I was able to fix the problem temporarily by booting to a Hard Disk Manager 17 USB drive and repairing the boot partition.  However, it came back off and on until the reinstall resolved the problem permanently.

The problem was in the and that z890 bios dont support csm/legacy and cant read Mbr drive as bootable.

 

Michael Assuming you were doing what i am and trying to move OS drive to new MB.  Did you have to fresh drive the z890 and start from scratch with a fresh OS install or find a way to get the drive to detect some other way?

I was able to use a bootable Paragon Software Hard Disk Manager 17 repair USB stick to rebuild the boot partition.  However, that may have only worked because I'd created the repair USB stick in the Windows system it was repairing.  However, it's possible that Hard Disk Manager 17 or other standalone repair apps could repair your boot partition if you have another system where you can download them and build the USB stick.
