No grub when install manjaro

I do that I can select windows or Manjaro manually but not grub appears

Are you referring to the Grub “menu” screen?

If that’s the case, you can change the GRUB_TIMEOUT and GRUB_TIMEOUT_STYLE options:

Post for reference:

No kernel selection menu during boot up even when i have 3 kernels installed

What is your GRUB_TIMEOUT_STYLE option? Look under the file, /etc/default/grub By default, it boots straight into the latest kernel, unless you interrupt the process with LEFT-SHIFT quickly enough. Otherwise, you need to change the value of the following options and sudo update-grub once again: GRUB_TIMEOUT_STYLE GRUB_TIMEOUT An example might look like: GRUB_TIMEOUT_STYLE=menu GRUB_TIMEOUT=10
