I am presently rebuilding my old system for my girlfriend just to have. She has purchased a new hard drive and a new case. I'm basically moving my old system to the new case and installing Windows fresh on the new hard drive. The problem is that the IDE DVD drive will not read the Windows 7 disc. I think it is because it is dual layer. Now, I was going to install Windows XP instead and call it a day but I do not have the SATA drivers disk nor do I have a floppy to install them from. I am having quite the dilemma right now. I have taken the dual layer DVD drive from my new machine and put it in the old one but I am not able to boot from the SATA DVD Drive for some reason. Does anyone know if this is possible? I want to be able to boot the Windows 7 disc so I do not have to install the SATA drivers independently and to also be able to reap the benefits of the 64 bit processor. Can anyone help me please?
