Cant boot into Windows after installing Ubuntu

nigwardtesticles

I wanted dual boot windows and Ubuntu so I followed this tutorial. I did everything that it said and installed Ubuntu. But when I restarted my PC it didn't show the GRUB menu and directly restarted to Ubuntu. Does this mean that I deleted windows? If I did delete it, how can I get it back?

I'm stuck so please help. Thanks

You should be able to go to a terminal and rerun grub to discover the other OS's on the machine.
Try sudo update-grub
