The quickest way to get a usable image is with oscdimg.exe from an already working Windows installation. Assuming D is your DVD-ROM, enter your 64-bit Windows 7 disc and type the following from a command prompt:
oscdimg.exe -n -m -bd:\boot\etfsboot.com d:\ win7x64.iso
Burn the resulting ISO and and Bob's your uncle. oscdimg.exe is a premastering tool from Microsoft part of the Automated Installation Kit for Vista and other packages but also available by itself via your favorite search engine.

Jimmetry said:Bumping... this is absurd. Not everyone has a Windows machine lying around. Surely there's a way to do it from a Mac.
What do I do??? Notice they say cannot open boot sector in 'D'.... even though I entered the dvd drive location as 'L'
oscdimg -n -m -b[COLOR="Red"][B]d:[/B][/COLOR]\boot\etfsboot.com l:\ win7x64.iso
where would it have copied it so I can burn the ISO to a dvd ??
I know this is an old thread but I came across this issue today installing Win7 64bit on my MBP. With jumping through all these hoops, it sounds like my MBP has a EFI32 and the newer Macs have EFI64, which caused this issue. Does this mean that 64bit Win7 wont run as well as 32bit? Since I have 4GB of RAM in my MBP, I want to use Win7 64bit to fully utilize the RAM.
64 bit Windows will run perfectly fine once you fix the disc to get it to work. I'm running Windows 8 Consumer Preview x64 on a MacBook Pro that I bought in 2007 and its running great.
Are you triple booting?
This solution is awesome! The Win7 installation doesn't even need to complete, it just needs to get far enough that VMWare recognizes that you have a valid Boot Camp partition. Super fast and smooth Win8.1 64 bit installation after that on my Mac Pro 1,1.Hi
I've installed bootcamp and i found a windows 7 stater edition in 32bits. Basically, you can do it with all the 32 bits windows.
I've installed the system, without any updates, etc... Just the basic.
After, i went back to Lion, and created a virtual BOOT CAMP machine in VMWARE.

If you have a Windows Install DVD and get this error; you can create an ISO image that can be burned with Disk Utility.
- Copy the contents of Windows DVD to a folder on Desktop named Windows7
- Open Terminal
- Change to Windows7 Folder using: cd ~/Desktop/Windows7
- This command on the next line will create and ISO named Win_Install on the your desktop:
- hdiutil makehybrid -o ~/Desktop/Win_Install.iso -iso -udf -udf-version 1.02 -udf-volume-name Win_Install -iso-volume-name Win_Install -eltorito-boot ./boot/etfsboot.com -no-emul-boot -boot-load-size 8 ~/Desktop/Windows7/

THANKS! Works for Mac only people!
Special thanks to jsuaggie above in post #69 for his instructions, they work great. If you are a mac only person, that has an older iMac and CAN NOT use a PC to setup your Windows install DVD properly his instructions work great. I have a genuine OEM Windows 7 Pro 64bit DVD that wasn't working, and after following his instructions, I am now installing Windows on the old Imac. This older iMac WAS using the 64 bit EFI firmware too. Once you have followed his steps, you can THEN proceed to go through the regular steps that Apple supply for you to setup Boot Camp using the supplied Boot Camp Assistant tool in OS X, just keep the now newly burnt DVD in the SuperDrive and you will be fine. I made an account just to share this I was so frustrated for many hours, thank you jsuaggie you saved my Christmas holiday!![]()
I actually found a way to do this without changing the disc at all! Yay! \o/
1. After selecting CD as boot device, immediately press "1" on your keyboard and keep it pressed.
2. When you see a black flash, press enter (without releasing "1"). This happens twice, press enter both times.
3. Keep "1" pressed until you see the disc has actually began booting.
