Since an attempted windows update the the pc is inaccessible and goes to a blue screen language selection and then into the troubleshoot options. There isnt a factory reset option available with the available options (none of the other option will repair it) how can I reset this?

I've tried using a windows 10 usb install and it wont boot from it despite me sestting it as first boot option.
