I want to boot my PC but don't have a 2nd PC or laptop in general and now I can't create a CD or stick for booting what should I do now
If you haven't installed a Win yet, you have to make sure that you get a boot stick somewhere so that you can install from the Win
There's no way around it
You can also order a Windows 10 installation medium (e.g. USB stick, DVD, etc.) from the Internet.
Otherwise, ask a friend if they could create it for you.
Either with a friend etc. Or buy a bootstick
