Just to ask if some else has seen this strange behaviour:
I just updated the system ( as usual via CLI pacman ) and noticed a new grub version.
As usual ( since kernel 4.18.x ) GRUB os-probe takes 12 minutes to check all the HDDs, so I let it run .
But after rebooting in the GRUB menu was updated but it lacked MS Windows and some other HDD Linuxes.
Putting in context:
I have 1 SSD ( Manjaro installed ) and 3 HDD; each HDD has their one local GRUB MBR installed.
I am commenting the detail in the SSD GRUB MBR boot installation.
I know that Manjaro is a bit picky with GRUB so ..
The update action did add and entry for "RED Core Linux" in another HDD (with a GPT table ) but missed the MS Windows in their own SSD .
The same grub-update action from Anti-X 17 ( with an older GRUB version, pointing to the local HDD with a GPT table ) did got correctly the Windows and other linuxes ...
Any comments or ideas ?
