If you get this error when trying to install windows 7 64bit on your Mac, then follow this guide.
“Select CD-Rom Boot Type:_”
Steps:
1 – Create 3 folders c:\windows7iso c:\windows7exe c:\windows7dvd
2- Download this .exe file and put into c:\windows7exe
3- Download a Windows 7 ISO from the ActionPack or MSDN website, or create an ISO file from your Windows 7 DVD. Move the ISO into the c:\windows7iso and unzip the contents (into the same directory) with MagicISO
4- Move .iso file out of c:\windows7iso (to anywhere else)
5- open a dos prompt, change directory to c:\windows7exe and type exactly as shown :
oscdimg -n -m -bc:\windows7iso\boot\etfsboot.com c:\windows7iso c:\windows7dvd\windows7dvd.iso
Now burn the windows7dvd.iso file to a DVD and proceed to install windows 7 on your mac!

Welcome to Fluxbox, im afraid we have no affiliation with the Linux window manager, so if your looking for that, turn around now.
Thank you, worked like a charm
I was unable to figure out how to use imgburn to extract the contents of an ISO file…
Easiest way, actually just burn it to a CD… or download a copy of MagicISO, which will let you explore the contents of an ISO easily enough !
this worked great, thank you sir. aye sir. thank you sir.
Hey there, Just to let you know this worked like a charm! Thks!
I cannot get to the “c” drive as there is no windows yet. What do I do to get back to Mac?
Holding alt/option during boot will bring up the boot loader. Should show you an Apple logo and a hard disk logo, use the arrow keys to choose the apple logo and off you go on another OS X Adventure…
where exactly do you create the c:/ folders if using a mac? am i supposed to create those folders in the boot camp drive? Or s this disc meant to be created on a windows systems and then used on a mac…?
Afraid the only way i know of doing it, is to create the disk using a windows machine and then use it on the Mac… sorry friend !
I did on my PC, works great, thanks!
“unzip the contents with imgburn”
How would I do this? Thanks for any help!

10x good work :)
After 2 days of pain and digging the internet, I tried this solution and guess what? It works!
I really don’t know how people come up with these kind of hacks though, but I’m glad they do :)
Thanks a bunch!
Does anyone have the iso where we can just download it, i dont have a windows machine
Can you take screen shots and post them ??
Beleive it or not, This fix got me a job :)
Thanks and a million credits to the poster and the creator of this fix. Cheers!!!
I may be as dumb as a bag of rocks, but I (I think like Phil) cannot find ANYWHERE where Imgburn EXTRACTS files from an ISO. So can I just copy the files after I’ve made it into a disk?
Hi friend! Greetings from Spain, you solve my problem and I can install my new W7 S.O.
The problem I found, is that I can´t make a new bootcamp partition (I´m using snow leopard and has two years old) and I need to reinstall the complete S.O.
And when I reinstall all the SO, I found that MacosX can´t install the windows 7.
But you solve all my problems.
If I found people in Spain with the same problem, I link to your blog.
Thanks !!!!
Using imgburn, u can just extract the files into the same location as the ISO file, it’s been a while since iv had to do this, but if ur having trouble still I might be able to redo it and post a video… Seems this is a pretty popular guide and could do with some clarification :)
The windows 7 .iso I downloaded from ms? What windows 7 .iso? and what’s ms? do you mean Microsoft? I haven’t downloaded anything like that – but I’m going to try and use the Windows 7 disk I have to do this. If it doesn’t work I’ll post another comment.
I’m a Microsoft partner, thus I have access to an online portal which has Microsoft software available as ISO files… I’m guessing u could just create an ISO from a CD…
Okay, I will try that.
It worked :) Thank you very much, sorry for my probably stupid question!
You can *not* extract ISO-Files with ImgBurn!
http://forum.imgburn.com/index.php?showtopic=2981&#entry34586
And ur right… Article updated, trusty magicISO :)
You can also extract ISO-Files with 7zip (Freeware).

After burning the disc with success … I have put it in the Mac and restarted holding the option key down. It brings me to the drive select screen yet the disc isn’t recognized.. Only my hard drive is recognized. Wtf?? I checked the contents of the disc and the file is there and is recognized on my Mac.
Im not sure what to suggest mate, can you try again, maybe the disk got corrupted somehow and isnt being reccognised by the boot system…
It’s been years since I needed to reinstall windows 7 on my Macbook Pro. I couldn’t remember for the life of me how I got w7 installed in the first place. Thanks for this page.
One note though, if you have the original w7 installation dvd, you don’t need to make an ISO out of it just to unpack into c:\windows7iso. You can just copy the content of the dvd straight into that directory. So you don’t really need MagicISO for this step.
I used my w7 desktop machine. w7 has a built-in ISO burner so I was able to create the mac-bootable installation disc without downloading extra software. Hope this simplify things a bit for others.
Thanks. This solved the problem I was having installing the Windows 8 Release Preview on my six years old iMac.
You are the man!!! TY for this!
Excellent Post. Able to install Windows 8 RTM 64 bit successfully on MacBookPro. Once again thanks to the author.
Thank you soooo much!!!! This really worked!!!:D
Thank you for your help. This worked on 32-Bit Windows 8 RC for my Macbook 2,1. I used Winrar to unzip in Win XP.
I used this tip to install Windows 8 Pro RTM on a MacMini 1,1. I wasn’t able to use the linked version of oscdimg.exe on my Windows 7 64-bit PC due to its incompatibility with 64-bit Windows. But I got an updated version of oscdimg.exe from the Windows 8 Deployment kit (free download here: http://www.microsoft.com/en-us/download/details.aspx?id=30652 ); it’s included in the Deployment Tools in that package.
The command line then worked as written (replacing a Win8 ISO for the Win7, obviously).
Do I use 8′s in the dos prompt and windows folders if i’m trying to install windows 8?
Thanks! Just as an extra, you can add the flag -l to define a custom volume label for the ISO image (which will be the name of the disc when burnt). Do not put a space between the flag -l and the name.
e.g. “oscdimg -n -m -bc:\windows7iso\boot\etfsboot.com c:\windows7iso c:\windows7dvd\windows7dvd.iso -lWIN7_EN_DVD”
will name the ISO/disc WIN7_ENG_DVD.
Also, the Mac wouldn’t boot Windows when using a DVD+R and a non-standard disc name. After using a DVD-R and changing the disc name to GRMCULXFRER_EN_DVD (the original name), it booted fine.
Thank you so much for this help! I just applied it to my Windows 8 64-bit version, and it worked perfectly.
I was stuck at the same question as everyone, else. I should mention that I changed the folder names suggested into windows8iso etc.
I can’t give you any details about my computer, but for the record, it’s not a Mac.
THANK YOU!!! Worked like a charm!
How do you create the folders in step one? I think I know to do everthing else accept step 5. any help would be appreciated.
How do you do step one? I think I know how to do everything else except step 5. Any help would be appreciated.
Step 1, just right click on the c drive and goto “new > folder” then name it to whats defined in the insructions…
or you can open a command prompt, hold down the Windows Key on your keyboard and press R, when the box appears type “cmd” and press enter, you should get an dos window appear, in that type the following;
1) cd \
2) mkdir windows7iso
3) mkdir windows7exe
4) mkdir windows7dvd
Thats it, done :)
Step 5 is all done through a command prompt, just do the WinKey+R and cmd thing again… all done from that dos window !
Thanks, I spent days and lots of my download allocation to get this working. So thank you very much!!! :)
