I have a Toshiba satellite c655d-s5200 laptop that was recently donated to me. It has windows 7 home premium OA pre installed with a product key under it but it won't boot up from the hard drive or Ethernet controller. I would like to know how can I boot the PC by using a CD/DVD as a bootable device. I have a blank CD disk with 700mb but don't have an copy or original windows 7 installation disk. How can I boot my laptop with jus a blank disk and using another PC under windows 10?
