Hello guys. I have a real problem that I dont know how to deal with. I try to reinstall windows on my Toshiba Satellite laptop from usb stick. I used Windows 7 USB DVD download tool for booting the usb flash stick. I tried both WIN 7 and WIN 8.1 installation. In bios I set the priority for USB. But when I save and exit, it just loads the old windows every time and no installation starts. I tried also my dvd with WIN 7 installation, it still loads the old win. I have done this before and I know that these installations are good, because they run on my other pc like a charm. Please give me some advice!
