Hello,
If you're trying to reinstall Windows, you have three options. You can reinstall Windows from Settings, using an ISO, or with a USB. All three options will reinstall Windows, but one requires a USB, the others don't.
To reinstall Windows from within Settings, open it, and then navigate to System > Recovery > Reset this PC. You can select to either keep your files and apps or remove everything. Then, you will be asked if you want to do a cloud reinstall or a local reinstall. If you have a strong network connection, I recommend going with the cloud reinstall. However, if you have a metered network connection or have OEM specific apps that you would like to keep, go with the local reinstall.
To reinstall Windows using the ISO, go to https://microsoft.com/software-download/windows11 and then scroll down to where you see "Download Windows 11 Disc Image for x64 devices". Select your language, and then download the ISO. This ISO will be about 7 GB, so depending on your Internet connection speed, it will take a while. Again, if you have a metered connection, you will want to go with the local reinstall from within Settings. Once the ISO is done downloading, open the ISO (mount it), and then open setup.exe. If you see a prompt for User Account Control, simply click "Yes". Let Windows Setup load in, and then when you are asked to check if the settings are correct, select "Change what to keep", and then select the option that you will like. Then, click "Next", then "Install", which will start the install process.
If you would like the steps for the USB reinstall (clean install), please let me know, and I will be happy to provide them. In both the steps mentioned, make sure that your laptop is plugged into a power source so that it won't die during the reset process. If you have any questions during the process, please let me know, and I will be happy to help!
I hope to hear back from you.
