Grub wasn't updated in the recent 13.6 Trixie update nor it seems that 
is going to be updated now. The only issue I had related to Grub it was 
mentioned in this post:

https://lists.debian.org/debian-user/2026/03/msg00353.html

but it doesn't make my system not bootable and I never heard/suffered 
about issue with Grub in all previous Stable releases (at least from 
Squeeze). I don't have UEFI partitions installed in my system maybe 
something else broke your boot sector or maybe the boot sector was not 
properly updated and it still pointed to the no longer existing old 
kernel image.

If you also don't have UEFI the package "grub-pc" could have issue 
installing Grub on the correct drive's boot sector (see my post above).
