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).

Looks like I didn't burn the ISO correctly. When I "connected" parallel's to downloaded image file, it worked. Thank you for the tip. –  dev.e.loper Sep 12 '11 at 15:53

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.

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.

I went through all the post, tried most of them and a lot of them were not making any sense. Unfortunately I cannot come up with the exact way I solved the issue but here is what I did.

  1. Delete your actual VM, it is no good.
  2. Update your Parallels Desktop, I am working with 8.0.18608.
  3. Create the VM using a brand new downloaded ISO for which I used a download manager (ex. Folx)
  4. Recreate your VM, it workes just fine for me.

Honestly I don't think the iso file is the problem. If I were you I would try with the one you have right now. After I updated my Parallels it wasn't working until I realized I was still trying to install with the VM I created with the previous version. When I deleted and created a new one it worked.

So if you are reading this, just update your Parallels, delete your VMs and start over, don't worry about configuration it didn't do anything good for me, IDE or SATA. Just make sure you start fresh.

Hope it helps, cause for me, none of the other posts helped.

Actually I have found out that this also occurs if you are using usb3.0 ports. If you only have usb 3.0 ports you need to go into the bios and tell it to treat them as usb 2.0 ports in preboot
