i can't install clear linux on dualboot with android

because clear linux does not occupy grub I cannot create an entry for recognizing the android bootable partition, could anyone help?

if you are on UEFI then you could probably choose to boot on the Clear Linux or Android ESP (inside your BIOS)

cannot create an entry where? in the boot menu? what is your bios/uefi version?
what device is it?

Maybe you could take a look at

and I believe you want to take a look at
