Set up dual boot with Windows 10 loads into windows without grub

I made a 20GB partition for Endeavour and managed to get it installed but don’t know how to get grub to show up. I should add that I can change boot order to get into Endeavour

Usually it’s Windows that doesn’t show up in the grub menu. Is this a UEFI system? Did you make sure secure boot was turned off in the UEFI BIOS and it’s best to turn off fast boot in UEFI also. If you can get into Endeavour after checking settings and then run sudo grub-mkconfig -o /boot/grub/grub.cfg

I managed to fix it by swapping the boot order putting Endeavour first. Should’ve updated this sooner but yes yes and yes to your questions.

Just mark it as solved.
