Need help reinstalling os x have tried everything.

So i stupidly wiped my hard drive of everything. Now i get the flashing folder on start up and I’ve tried every control possible to get it to boot to disk utility, network install won’t load when i press N on start up the globe symbol flashed like 4 times then the ? folder will appear, Tried to boot off usb it can’t find the usb. Thought i may have damaged the HDD when erasing it so i bought an SSD. I formatted it to HFS+ on my windows computer so the iMac would recognise it but i’m getting the same results as before.

I have literally tried everything, every command, every way to boot and still nothing.

This apple is about to become a pear when i throw it out the window!
