Description DYM 2019-09-06 10:51:07 UTC

Bootloader has forgotten how to boot from BSD-labels without MBR or GPT.

It is reproduced both clean install on the BSD-label, and when upgrading to 12.0

Replacing the loader from 12.0 with the loader from 11.2 (simple overwrite) solve problem.

Comment 1 DYM 2019-09-06 12:08:07 UTC

After installing the system on BSD-label, before replacing the loader on the screen:
====
BTX loader 1.00  BTX version is 1.02
Consoles: internal video/keyboard
BIOS drive C: is disk0
BIOS 638kB/3603392kB available memory

FreeBSD/x86 bootstrap loader, Revision 1.1
Startup error in /boot/lua/loader.lua:
LUA ERROR: cannot open /boot/lua/loader.lua: no such file or directory.

can't load 'kernel'

Type '?' for a list of commands, 'help' for more detailed help.
OK
====

To replace:
1) booting from ISO FreeBSD 11.2, switching to the shell.
2) Mounting the root partition of the disk:
# mount /dev/ada0a /mnt
3)Copying the loader from 11.2:
# mv /mnt/boot/loader /mnt/boot/loader.12.0
# cp /boot/loader /mnt/boot/

After replacing the loader, the load is normal.
