Hello @KEIJU
Abstract and seemingly illogical short questions usually lacking sufficient information get the response deserved.

Same as your previous question

You need to describe what you are doing in more detail.

If you have grub its configuration will be controlled by one linux only.
It you have other linuxes or Windows installed , and you want grub to put them in the boot menu, you should go into the Linux that controls grub and do update-grub. Then boot and you will see any other OS’s that it detects in the grub menu.
