It's possible you can fix this by unplugging a USB device or setting the PC's BIOS back to defaults. If that doesn't fix it, this boot disk will work around boot sector issues and missing boot files; but it won't make a difference if you have an incorrect BIOS configuration, a large number of missing or corrupt files, a bad hard drive, or Windows isn't installed.
It doesn't have to be blank, but whatever is on it will get erased. You will need a working computer to create it.
A smartphone or tablet won't cut it, if you don't have a working PC try a friend, neighbor, library, FedEx Kinkos, or Internet Cafe in your area. What if my other PC isn't Windows, but a Mac / Linux or another OS.
