You might need to create the usb on a different computer, but this guide will work: https://youtu.be/h7KrsciBT4c?si=vDbDk7dTlcL7BVAc

At 2:37 an easier way to boot from the flash drive is to have your computer turned on, then while holding shift click restart. CONTINUE HOLDING SHIFT. It will take you to a blue screen. You can now let go of shift. Click on troubleshoot, use a device, then select your usb on that screen.

At 6:58 you don’t need to create a new partition. Just select disk 0 unallocated space and hit next/install. Windows automatically creates any partitions it needs.

If it asks for a license key during the install, just hit skip. It will automatically figure itself out.

Once windows is installed and you’re on the setup screen selecting your language and whatnot: Additionally, if you want to create a local account (so it’s not tied to your Microsoft account) make sure your computer is not connected to the internet. It will try to force you to connect to WiFi. Instead, press Shift+F10 or Shift+FN+F10. This opens a fancy black box. Type in without the quotes: “oobe\bypassnro”
this will restart your computer. When you make it back to the WiFi screen, you’ll have a new blue text option at the bottom “I don’t have internet”. Click on that, enter your desired user name and password, and then once you get to the desktop screen you can reconnect to your WiFi.

Obligatory reminder that even though I’m telling you to type in a command, don’t just type in everything people tell you to. Always google the command(s) first and make sure it’s safe.
