Inside the BIOS (press DEL or F4 when the computer starts up to enter the BIOS) there will be an option to find something called "boot" (mostly only appears when you are inside ''advanced settings'' in your motherboard), here you will be able to see how your computer boots up, typically a computer will only have one option; the hard drive, which will be called the same as what the hard drive is actually called, eg "KINGSTON NV1 1000GB M.2 2280 NVME SSD", this means that we have a working disk in the system that we can boot from.
However, sometimes it will also say "UEFI: PXE Ipv4 Realtek PCIe GBE", and if it is at the top of the queue, the computer will automatically try to boot on the Internet, and this can cause a problem when you try to start your computer.
It won't boot normally into Windows, and so the two have to be swapped so that the one called "Windows Boot Manager" is at the top, because that means it will be the first thing the computer tries to boot into, and since it does so successfully , it will not try the second method.
Below you can see how to fix it if it says UEFI.
