Hello, thank you for reaching out to Microsoft Q&A.
See the video at the following link for guidance on how to create a USB bootable installation media:

Make sure you repair the boot configuration files as suggested by the AI assistant.
bootrec /scanos
bootrec /rebuildbcd
bootrec /fixmbr
bootrec /fixboot
Note - Performing a clean install will delete all of your files, apps, and settings, so instead of selecting Install now, choose the Repair your computer option to troubleshoot and fix the issue without erasing your data.
