Hey guys I really need help on this one... I just downgraded my Toshiba Satellite P75-A7200 to a version of windows 7. But unfortunately I picked the basic version on accident instead of the professional version like I intended to do. Now basically the issue im have is getting the laptop to boot off of the DVD install disc. I still have my BIO's set up the same way I did to downgrade in the first place and it will just not boot. Also, the laptop will not connect to the Internet even when plugged in with an Ethernet cable. If anyone has had experience with this or think the could help me please get back to me as soon as you can thanks a lot guys!
