I had to do a re-install of Windows 10 on my older laptop (HP X360). I used the Windows Media Creation Tool to install a basic system. Everything seems to be working and I have installed most of the programs, address book and Favorites that I need. BUT, one thing that I don't understand is when I power on, I get a screen with two OS options to boot. One boots after 6 seconds and boots into the new install. If I select the other, it fails to boot, I think it is trying to boot a USB stick. I have the BIOS set to boot to the default boot manager first and USB second and DVD third. There must be a BIOS option that would stop the two options, but I don't know what it is. I would appreciate any advice.
