You will need to change the boot options of the grub menu. Take a look a this thread:

Dual boot with windows as prime

In /etc/default/grub, the GRUB_DEFAULT=0 parameter can be changed to match your desired first boot option in Grub. If your Windows is 3rd in the list, you want to change that '0' to a '2', then you must run sudo update-grub to make changes permanent. When you reboot, your Grub will auto-select the third option in the list, and proceed with booting. Just remember '0' = 'first', '1' = 'second', etc..

bcdedit /delete [the Value from the Entry]

After that Your System should start normaly into Windows again. That was a short Describtion. I wrote here in a Thread a more detailed Describtion with Pictures if You want more Details:

Is zorin os support legacy booting?

Okay, I will try to describe my Way to delete Linux from my Dual-Boot System. For that I start into Windows. There I open the Disk Management.

In Your Case with the manually created Partitions You could have more than me. You make a right-click on the Linux Partition an choose the Option to delete it. In my Case stands there ''Volu…

I'm afraid I don't know that, but @Ponce-De-Leon's advice looks good. I would just re-install whatever OS I need and use the entire disk, so there's no chance for me to screw up

Try the GRUB CUSTOMIZER application which might do what you need to do with a GUI.
