* What did I EXPECT:
- Boot record is loaded correctly.
- Windows boot manager is loaded, or "custom" boot manager is loaded.
- Boot manager finds and loads BCD storage archive (Boot Configuration Data).
- Windows Boot menu is presented, boot into windows.
- in a privileged cmd, bcdedit loads system BCD; easyBCD, if present, loads
system BCD.
- Boot tab in msconfig is "unlocked", and values are editable.
* What did I GET:
- Boot record is loaded correctly.
- Windows boot manager is loaded, or "custom" boot manager is loaded.
- Boot manager DOES NOT find BCD storage archive, some backup is loaded.
- Windows Boot menu is presented, boot into windows.
- In privileged cmd, bcdedit DOES NOT load system BCD, throws error:
C:\Windows\system32>bcdedit
No se pudo abrir el almacén de datos de configuración de arranque (BCD).
El sistema no puede encontrar el archivo especificado.
- EasyBCD is unable to load system BCD, offers to load alternative BCD.
- In msconfig, the Boot tab is locked and unusable.
Other side effects:
- Is not possible to change certain file or archive permissions in c:\,
c:\boot, and other places.
- Problems with backup software acronis, error on restore image "autochk.exe
program not found skipping autocheck"
is related.
- Problems with "custom" loaders
###################################################################
Conducted tests:
In a "locked" state, entered in Repair Mode:
No windows installation is recognized.
Startup Fix does not solve the problem.
In Repair Mode, tried to run from a repair console:
bootsect /nt60 c:
command success
still locked
bootrec /fixboot
command error:
"Element Not Found"
bootrec /FixMbr
command success, no point
still locked
bootrec /RebuildBcd
finds windows installation [c:] on sda1
option to add to BCD
command error:
"The volume does not contain a recognized file system"
still locked
bootrec /scanOs
command success
finds windows installation [c:] on sda1
still locked
Load system again, this time booting from sda directly (configure boot from
1st disk in BIOS)
Repeat steps above.
Still locked.
###################################################################
Found Workaround, Temporal Fix:
Load system again, booting from sda directly.
Launch administrative console, and run commands:
diskpart
select volume 1 (the system volume)
select partition 1 (the system partition)
active (make partition active)
System is now unlocked, BCD is found by loader, boot tab in msconfig is
unlocked and works
easybcd loads system bcd without problem, bcdedit command throws current boot
menu configuration.
The problem:
Everytime windows system loads through Grub2, system is locked.
If system loads "offline", system is unlocked.
###################################################################
Conclussion:
Grub2 loads the bootsector directly.
My guess is that grub2 doesn't pass the "active" parameter to the target
partition properly.
parttool (hdx,y) boot+ doesn't work as advertised.
parttool ---- boot+ should work as "makeactive" command from legacy grub.
