"Select CD-ROM Boot Type:" error during Windows install
Which version of bootcamp 4.x do I need to install Windows 7 (64 bit) on an iMac7,1 with Yosemite?
Specs: 64 bit Core 2 Duo, 4GB, 16GB Flash, optical drive, Windows 7 install DVD
Everything goes fine until during the install process Mac reboots to install windows then:

Select CD Rom boot type:
I can't enter anything because keyboard and mouse are unresponsive and I assume the correct drivers were not loaded.
iMac is mid 2007 24" 64 bit (says profiler/other internal monitors). Have downloaded various boot camp versions, followed documented instructions, stood on my head and spit nickels, and still get same error (Select CD Boot ROM type). Made ISO file with Mac Disk Utility (create and change .cdr to .iso) Didn't work either.
After further review, seems that I misread Apple support table which show this model uses Boot Camp 4 for 32-bit Windows 7. Genius - bought install DVD for 64-bit :-o So I guess that's why it won't install.
Going to try suggested method of creating ISO from W7 store-bought DVD on Windows machine just for giggles and see what happens. Then probably go buy the correct DVD for 32-bit :-( Thanks for the info :-)
The problem you encountered occured before the Boot Camp drivers are installed. So, the drivers are not the problem. The correct drivers for Macs can be found at Boot Camp: System requirements for Microsoft Windows operating systems. In your case, the drivers can be downloaded from Boot Camp Support Software 4.0.4033. Also, the drivers can be downloaded using the Boot Camp Assistant. By the way, I used the same drivers to do a clean install Windows 8 (64 bit) on my iMac7,1 (20-inch, Mid 2007).
Your actual problem is with the DVD itself. As you might guess, it came with two ways to boot. You need to remove one of them. You are using a Windows 7 DVD. I was having the same problem with a Windows 8.1 (64 bit) DVD. The procedure to repair should be the same.
I used a windows 8.1 machine and a copy of the program oscdimg.exe
from Microsoft. The procedure should work just as well using a Windows 7 or 10 machine.
To begin, you will need to copy oscdimg.exe
to your desktop. There are many web sites where a copy of this file can be found. I used oscdimg.exe
Version 2.55 (x86). If you want to be sure you are using the same one I used, follow the steps below.
-
Go to the web site The Windows® Automated Installation Kit (AIK) for Windows® 7 and download the iso. This iso file is 1.7 GB in length.
-
Open the file
Neutral.cab
. If you are using a Windows 7 machine, you will need to burn the iso on to a DVD. The instructions can be found here. Open the new DVD to find theNeutral.cab
file. It is faster to copy theNeutral.cab
file to the desktop before opening it. If you are using a Windows 8.1 or 10 machine, right click on the iso icon and select Mount.Neutral.cab
will be one of the files in the opened folder. (Note: Opening the file can take a while.)One way to avoid burning a DVD would be to copy (or download) the iso file to a machine running OS X. The iso file can then be mounted by double clicking on its icon.
Neutral.cab
will be one of the files in the opened folder. You will need to copyNeutral.cab
back to a Window machine. I tested this using OS X 10.6.8. I assume this procedure would work using any newer version of OS X.Another way to avoid burning a DVD would be to copy (or download) the iso file to the
~/Downloads
folder of a machine running Kubuntu (or perhaps some other Linux). The following commands can be used to extract theNeutral.cab
to the~/Downloads
folder. You will need to copyNeutral.cab
back to a Window machine. I tested this using Kubuntu 18.04.5 LTS.cd ~/Downloads mkdir windowsiso sudo mount -o loop,ro KB#AIK_EN.iso windowsiso cp windowsiso/Neutral.cab . sudo umount windowsiso rmdir windowsiso
-
Using a Windows 7, 8.1, or 10 machine, extract
oscdimg.exe
from theNeutral.cab
cabinet file. The x86 (32 bit) version is namedF1_oscdimg
. The x64 (64 bit) version is namedF3_oscdimg
. Right click on the file of your choice and select Extract. Place the extracted file on your desktop. Rename the extracted file tooscdimg.exe
. (I did verify the correctness of this procedure by installing the entire package and binary file comparing the installed x86 and x64oscdimg
files withF1_oscdimg
andF3_oscdimg
, respectively.)
Next, make a new Windows 7, 8.1 or 10 installation DVD, follow these steps. The procedure was tested using a Windows 8.1 installation DVD.
-
Make sure a copy of
oscdimg.exe
is on your desktop. -
Place the original Windows 7, 8.1 or 10 installation DVD in the optical drive. If using a Windows 8.1 or 10 machine, then a Windows 7, 8.1 or 10 installation iso file could be mounted instead.
-
If you are using a Windows 7 machine, open a Command Prompt window by clicking the Start button , clicking All Programs, clicking Accessories, and then clicking Command Prompt. On a Windows 8.1 machine, look for the Command Prompt icon on the Apps page. On a Windows 10 machine, look for Command Prompt under Windows System on the Start menu.
-
Change your working directory to the desktop by entering the following command in the Command Prompt Window.
cd %homepath%\desktop
-
Assuming D: is your DVD drive or drive letter assign to the mounted Windows installation iso file, enter the following command. Be sure to replace the letter before each : with the drive letter of your DVD drive or mounted file. The file
new.iso
will be created on your desktop.oscdimg -n -m -bD:\boot\etfsboot.com D:\ new.iso
Note: For more information, see the Microsoft website Oscdimg Command-Line Options.
Using this command, on a Windows 8.1 (64 bit) DVD, produced the following output.

Burn
new.iso
on to a DVD. The instructions for a Window 7 machine can be found here. The same instructions can be used for a Windows 8.1 machine. For a Windows 10 machine, find thenew.iso
file in the File Explorer, then right click on thenew.iso
file and selectBurn disc image
.Note: The current 32 bit Windows 10 (20H2) release can be burned to a DVD or a rewritable (RW) DVD. However do to the larger size, the current 64 bit Windows 10 (20H2) release can only be burned to a dual layer (DL) DVD.
You can also transfer the
new.iso
file to a OS X machine and burn to a DVD using the Disk Utility. -
Finally, install Windows 7, 8.1 or 10 using the new DVD.
- After selecting CD as boot device, immediately press "1" on your keyboard and keep it pressed.
- When you see a black flash, press enter (without releasing "1"). This happens twice, press enter both times.
- Keep "1" pressed until you see the disc has actually began booting.
