So, in my mac, I don't have an os. I think I tried every way to fix it. I tried to boot from a USB but my mac sees USB in Disk utility in recovery mode but not on starup. I tried reinstalling OS X but I see the macOS Installation Couldn’t Be Completed. And now when I try to reinstall I can't see my hard disk. I really don't know what to do and really need help. I hope someone can help me...

Hi,
If your MacBook Pro has intel processor, resetting NVRAM could solve the issue.
Reset NVRAM or PRAM on your Mac - Apple Support
If it doesn't help, you'd better make Genius Bar reservation if your local retail AppleStore is open or find opened local Apple Authorized Service Provider to install macOS on your MacBook Pro, as far as I know, it's free.
Genius Bar Reservation and Apple Support Options - Apple
