background
The last two days I saw Manjaro upgrade quite frequently, and this morning I also saw Grub update. Of course, this is not the point. The thing is that when I started up tonight, I noticed that there was no boot boot interface, because work and family need Win10 system (dual system) by default, but this time I entered the Manjaro login interface
Anticipate the future, please continue to watch patiently

Ha, really when I tell a story?
Let's deal with it directly. I believe everyone's time is precious!
The following content comes from: Manjaro community forum, because my English is ordinary, I directly trust the original text to avoid misleading
After the most recent update on 8th March 2021, the Grub menu disappeared.
I managed to get the menu to reappear by running the following command
sudo nano /etc/default/grub
and then editing the grub file and changing the following
GRUB_TIMEOUT_STYLE="hidden"
to
GRUB_TIMEOUT_STYLE="menu"
sudo update-grub sudo grub-mkconfig -o /boot/grub/grub.cfg
However both my Windows 10 (on the same SSD ) and my 2nd (backup) Manjaro installation on a second drive HHD do not appear in the Grub menu anymore. They are both on GPT partitioned drives with EFI boot.
After running os-prober I get the following
sudo os-prober /dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi /dev/sdb5:Manjaro Linux (20.2.1):ManjaroLinux:linux
I can boot into both Windows 10 (SSD) and my 2nd Manjaro installation (HDD) if I choose the appropriate device from the BIOS, but they no longer appear in my Grub menu.
If anyone can help that would be greatly appreciated. This exact problem has also occurred on one of my separate machines which is much older, Windows 10 was lost from the Grub boot menu.
Still no Win10 boot?
After going through the above process, do you find that the Win10 boot menu does not appear?
This step is very important
Manualy add the line GRUB_DISABLE_OS_PROBER=false
to /etc/default/grub
Run sudo update-grub
Remember to add a command, then regenerate the menu configuration file, and then restart to see if it is back?
Enjoy!!
