I'm trying to boot from an old Vista disk but I'm not getting anywhere. I think my best bet is trying to install windows from a usb instead. How would I go about doing that? Like I said, when my computer boots up I can't get anywhere since the hard drive is formatted. Thanks!
You can boot from any lan computer or usb too but for that you have to change your boot priority. You will find it in the bios settings. But to boot from usb you need a bootable usb drive having bootable iso file of ur OS.
