Clean install of high Sierra

I did a restore from an AirBook that has slightly different hardware then the target. I did a full TimeMachine restore. The entire computer is now super slow. I want to wipe the target one and start over . Don’t I have to create a bootable USB OS? What are the steps ?

This is the steps I usually take.
1. take a backup if you are worried about any data lose.
2. You need to create a bootable drive of macOS High Sierra , before reinstalling the OS again. Go to the Mac Store and download the OS install
3.Restart computer and hold down Command-R to open in recovery mode.
*Click on Disk Utility in the OS X Utilities
* Select your Startup Disk, and click Erase tab at the top of the window
* Click Erase to confirm
This will delete everything from your disk
4. Reinstall a new copy of macOS using your bootable drive you created.
