I have tried to format my computer, to then install windows 7. I have tried with both of cd and a USB to boot up. When i tried to boot with my cd, the cd/dvd room didnt show in the booting options, but when I tried with the USB, nothing happend and the computer started to drive normally. I've read that the booting options wasnt able make permanent changes, and a link about how to change it. The link didnt say me anything about how to fix it. Right now im using a HP Pavilion dv6-7030eo.
Does anyone have an idea how to fix it ?
