Can’t boot into Ubunt after installing side by side with Wondows

So today I installed Ubuntu on a partition on my Hard drive, which already had windows 10 installed. When I boot up my laptop windows boot manager automatically boots into windows. I have heard that I need to enable GRUB but I’m not even sure how I can get back into Ubuntu. I tried enabling UEFI in boot options but I can only see windows boot manager and not an option to boot into the Ubuntu partition. Any help would be great.

Edit: Laptop model is Dell Inspiron 3542 – Ernie
