I am preparing my desktop pc for sale and was just trying to do a clean instal of Windows to get rid of my file history .
I have just tried to re-instal windows 10 from a USB thumb drive but come up with a message "Operating system wasnt found. Try disconnecting any drives that dont contain an operating system"
I am able to get to the BIOS by pressing F2 but not sure what to do next
The PC was working well before I tried this
Thanks in advance
