Create Windows install disk option in Lion Bootcamp?

am currently running Lion on my late 2010 Macbook Air. The new bootcamp has an option to create windows 7 installation disk from usb and iso. I have both but bootcamp won't let me select that option, any ideas?

If I go to FAQ on bootcamp support page, it says

Support for the Windows 7 ISO installer Install Windows with an installation disc you provide or, on Mac computers that do not have an optical drive, with a USB flash drive that contains a Windows 7 ISO image downloaded from Microsoft. The Boot Camp Assistant will offer to create this image on supported computers.

Is my MBA not supported by bootcamp assistant to create usb install disk>

MacBook Air, Mac OS X (10.7.2)

I have a late 2006 iMac with a failed SuperDrive. Apparently the firmware is too old to boot from USB flash drives, even using refit. I know that the USB flash drive with the .ISO is working, because I have no problem in booting it from a PC.


Now, what magic needs to be done to get Boot Camp Assistant to recognise a perfectly valid mounted .ISO? :-) I know, the problem is that it needs to reboot from it.


An alternative would be to format a small, bootable partition on the hard disk instead, boot from it, install Windows on a different partition, and delete the small partition. This is actually how I have installed Windows and Linux on old PCs for the past decade, when they had neither a working CD/DVD drive and could not boot from anything not directly connected to the motherboard. How to do the same on a Mac eludes me. I've even tried to install Windows from Parallels on an empty, Windows-formatted partition, but Parallels refuses to create a bootable partition that way (it just creates a virtual machine inside that partition).

Thank you so much for the contribution. I think I'm closer to be able to install Windows 7 using BootCamp... However, after all this, when it boots from the USB drive, a black screen with white letters appears saying something like there is no bootable device, that I should connect one and press enter. Of course this isn't true, because I have the bootable USB I just created thanks to your detailed and perfectly explained instructions.


I know this is a relatively old post, but do you have any idea about this? I've been trying to isntall windows for weeks with no luck...


Thanks in advance

This is how you fix it.

Go to disk utility and select your hard disk drive. (Your big drive that holds Mac HD)

Mine is 500.11 GB bla bla bla

Anyways look at the rectangle where your drive is to the right and if you look in the bottom right corner there is three little lines, drag those up so there is room for windows, then run bootcamp 🙂

DO NOT follow this advice, it is incorrect.


Use Boot Camp to create the Windows Partition, never use disk utility.

As @Csound1 said, only use Boot Camp Assistant to make a Windows partition, it does more checks to make sure that it will work right with Windows. Disk Utility is fine for making partitions for the MacOS, storage, etc.


@CFD.12, You should really just make another post for your problem as it should get a lot more attention as a separate issue. Make sure you list your model/year computer you have so we can give more detailed information.

Make sure you explain what you have done so far, what exact problems your having and any other information you think is needed.

If you haven't yet try searching for something like "No bootable device" as it may have your computer model listed with a fix, it seems every one has a different fix sometimes.


If you haven't yet here's a few places to look for information:

Boot Camp main page.

Boot Camp 4.0 FAQ information.

and the Windows 7 FAQ.
