I am new to Mac and have recently got my hands on a new 17" MBP. The MBP is a 2011 model dating from about May. Not wanting to step 100% away from Windows I want to install Windows 7 as well and run Mac OS. I have tried installing Windows 7 32-Bit and it worked absolutely fine - no problems at all. However, when I tried to install 64-Bit Windows 7 I ran into a problem very early on in the installation. Before the part where you select the partition to install Windows on, I get a "Load Driver" message which reads: "A required CD/DVD drive device driver is missing. If you have a floppy disk, CD, DVD, or USB flash drive, please insert it now." I cannot eject the DVD to replace it with the Windows Support DVD that I burned (which I assume has the relevant drivers on), so I am a bit stuck. I tried googling and a few people suggested burning the disk at a slower speed, which I did and it made no difference at all. The fact that 32-Bit works lets me know I am doing things right, there must be something about the 64-Bit that the MBP doesn't like. Any help much appreciated. I have 8GB RAM and would like to use it all with both Mac OS AND Windows so 64-Bit is preferred. Thanks in advance.
