I wanted to reinstall windows, but my usb flash with windows flash wont boot

So I think probably my files are corrupted so I wanted to install windows again. Through windows installation flash I changed the disk format to gpt through cmd where I wanted to install windows. So after this I restarted my pc and started booting through the flash. And it just won’t boot but like 2 minutes ago it booted normally. Now it is stuck on loading screen with windows logo. Any help would be great.
