I'm installing Windows 7 on my Mac via Parallels. During installation I'm getting. "A required CD/DVD drive device driver is missing." message. Doesn't give me any option to proceed further. What am I doing wrong? p.s. I hit same message using bootcamp. I'm using Macbook Pro OS X, Core i7. Trying to install Windows 7 Pro 64bit.

This error commonly occurs when the Windows 7 DVD, or the ISO image used to create said DVD, is corrupted. I see this at work once every month or two so know it well. Re-download the Windows 7 ISO image to use with Parallels. Also re-burn the new ISO image to DVD if you still need a physical disc (for Boot Camp). If this error occurs with a retail DVD try and ask for a replacement or check that your optical drive is in full working order (having tried using a CD/DVD lens cleaner on it first). |

Everyone seemed to think that re-burning the disk would fix the issue. It did for a lot of people. But I had a purchased copy that I didn't burn. The fix for me was to let Windows boot up. You'll see the black screen with a progress bar where the windows installer starts up. Start tapping F8. You might have to hold Alt/Option while tapping. I tried both just to be sure the menu would pop up. Then select: Disable Driver Signature Enforcement. Doing that let me continue through the installer. |

You are using the USB flash drive option. Avoid booting from a USB flash drive; use a bootable DVD for installation and this will never happen again. |
