So after installing Ubuntu, I wanted to get rid of Windows. So I installed GParted and then looked through it. I deleted just 1 Partition and restarted my System.
Now ever since I installed Ubuntu(Which is today), everytime I booted-up my PC, it would automatically go onto Windows and then I'd have to boot-up Ubuntu from there. And since I've deleted 1 Partition, I cannot get back into Windows. All it shows is the Troubleshooting-Panel and what OS I want to boot-up(Luckily enough, I can still boot-up Ubuntu).
I really want to recover this Windows Partition. I'm really scared in case I can't get Windows back or I've broken a really important part of my PC.
