How to fix formatted c drive

[jastly02]

I was trying to format my c drive (My computer drive) so I can install Windows 10 from my usb drive, because my computer had a lot of problems wrong with it. but it was a GPT partition so I couldn't do it, so now whenever I start it up, I get the BSOD (The Blue screen of death) any way to fix this? Also:my computer is a HP Stream Model: 11-r015wm

easiest way to do it is get a windows usb installer from the media creation tool. let the installer do the cleanup/format. if you dont mind losing all the HP partitions that came with your laptop and ull lose all the HP recovery functionality, just format the system partition. but looks like you already deleted all the partitions hence the bluescreen? :/
