Accidently deleted volume c while reinstalling windows 10

My pc was lagging very much in task manager the disk usage was 100% and slowly slowly some win32 files were deleting automatically but I was not aware about it and I thought to reset my pc but it was not happening it was showing win32 don't have such file. Then I researched about it and I came to know that its better to reinstall windows . So accidentally I deleted volume c and while installing its shown that windows can be install in gpt file.

So how I install windows now please help me. I have not told anyone in my house and I don't have money to give my pc outside for repair. Please help me.

Your thankfully
