You'll have to be more specific. Exact system specs would be helpful. And exactly what is it doing?? Blank screen? The loading circle continuously spinning? Hard drive activity light blinking? Freezing on boot? Doing absolutely nothing when power button is pressed? You have to be as specific as possible.
Go to https://www.microsoft.com/en-us/software-download/windows10 and download the Media Creation tool by clicking on "Download tool now". Find the downloaded file in File Explorer, double-click it and follow the instructions. You will be prompted for your USB stick. Please be advised that all data on the stick will be deleted. When the process is complete, put the stick in the laptop, press the power button and when the HP logo is displayed, press the ESC key and look for something like "Boot Device Options" and press the appropriate key. The USB stick may show up as a USB hard drive. Use the up and down arrow keys to select it and press "Enter".

As has been mentioned, sometimes the devil is in the details.
For instance, if you had a Dell System and had replaced the NVMe drive, Win 10 would install but a reboot would not be able to see the drive due to the SATA controller being set to RAID.
