Dualboot without windows option in bootloader

[The Low End Theory]

Hello, I would like to install Ubuntu alongside my existing Windows 8 install, but I want my PC to boot directly into Ubuntu without hitting a boot selection menu, is there a way to set this up so that I could run a command in Ubuntu to reboot into Windows?

Thank you.

Is this UEFI or BIOS install?

Not sure with all the grub updates if this still works or not.

Title/Name must match exactly to system as found by os-prober. copy from here:
gedit /boot/grub/grub.cfg
