Hi. I'm David, and I'm happy to help you.
See the article below for instructions on how to start your computer in safe mode.
At the "Startup settings" step, press 4 or F4 to start Windows in Safe Mode.
Below are instructions for creating installation media on a USB flash drive.
(You will need to create the installation media on a working Windows computer.)
(You can create the installation media on an empty USB flash drive with at least 8GB.)
- Download the Media Creation Tool from the link below;
https://go.microsoft.com/fwlink/?linkid=2156295
- Double-click on the downloaded file to run the tool;
- If prompted by UAC (User Account Control), click on "Yes";
- Read the terms and click "Accept" if you agree;
- Leave the "Use the recommended options for this PC" box checked and click "Next."
- Select "USB flash drive" and click "Next".
- Connect the USB flash drive you want to use, click the "Refresh drive list" link, select the USB flash drive, and click "Next";
(Note that the files on the USB flash drive will be deleted. Make a backup of the files if necessary.)
- Wait for the procedure to finish and click "Finish" when the USB flash drive is ready.
If you would like more information, please give me details of what is happening so I can understand the situation.
Feel free to ask back any questions.
