How can I fix dual boot with Ubuntu after installing Manjaro alongside it?

Question

I installed Manjaro alongside Ubuntu and now it boots straight into Manjaro without the option of loading Ubuntu. How can I fix this? I'm not wanting to reinstall the grub.

Thanks to two of you. I found that if I hold c during startup the menu will appear. There's an edit to the grub file to make it happen automatically.

For permanent change edit:

/etc/default/grub  

place a # symbol at the start of line GRUB_HIDDEN_TIMEOUT=0.

Save changes and run:

sudo update-grub
