Create Windows install disk option in Lion Bootcamp?

I followed that guide and installed windows 7 on the disk. Now I am trying to boot from the usb and I can't seem to make that happen. I downloaded rEFiT to see if that would help and it hasn't. What should I do?

EDIT:

I am going back through boot camp to see if that will work.

Went back through the Boot Camp Assistant and selected the option to install windows 7, allowed 20gb of space and click partition. it finished and now I have a windows device, but I still cant install windows from the flash drive. I have all the install files on the drive via UNetBootin

Thank you for this thread i got it to work wierd thou that numerical order makes the difference you guys are a godsend

What string is for Imac 11.1 late 2009?

For 10.6 and earlier,( Lion is similar but the windows are a little different.)

Apple Menu (upper left, Apple icon) About This Mac/ More Info.....(at the bottom)/ Make sure Hardware is selected, then your looking for the Model Identifier-----iMac x,x

Read all the posts and add your numbers where it's requiered. Just copy past another line in and delete their model and add yours. You may need to use the coma instead of a "dot" in order for it to work. iMac x coma x

<string>IMAC111</string

<string>IMAC11,1</string

dont't working

You need to look on the "Boot ROM Version:" filed rather than the "Model identifier" for me it is Boot ROM Version: MBP81.0076.C2 so the string would be MBP81.

I add 2 strings

<string>IM111.0034.B02</string>

and

<string>IM111</string>

DONT WORKING

(grey option USB)

Oh, yes, this worked like a charm with my MacBookPro3,1

I don't know if it is important but I repaired permissions with Disk Utility.

Thanks a lot, great work, brilliant!

This ordering tip worked fine for me

I'm having same problem... the check box is greayed out. I have my 8GB usb 2.0 Flashdrive plugged in and a windows 7 IOS on my desktop. I'm running Lion 10.7.3 and have a macbook pro late 2010 model. I want to vbe able to use a flashdrive to boot off to install windoes 7...

I looked in the package contents and found this in the info.plist:

It may be relevent but I don't know...

Hope Apple looks at this forum post soon and fixes it... 😀

Macbook Air 3.2

I bought Lion just for this feature and it's greyed out.. Simple explanation "why" from Official Apple Support would be nice

great man, great !!! 🙂

Thank you very much for the solution, this worked.

Of course, as someone else pointed out, the order of the entries seem to be important.

This is how I made this work

My System: iMac 27-inch, Mid 2011 Mac OS X 10.7.4

About This Mac -> More Info -> Sytem Report

Note: Model Identifier: iMac12,2

Copy: Boot ROM Version: IM121.0047.B1F

Finder -> Applications -> Utilities -> Select Bootcamp -> Show Package Contents

Select Contents -> Get Info -> Unlock -> Change Sharing & Permissions to Read & Write for all 3 Names

Contents -> Select Info.plist -> Get Info -> Unlock -> Change Sharing & Permissions to Read & Write for all 3 Names

Info.plist -> Open in Xcode -> DARequiredROMVersions -> Create an item and add in the right logical order. In my example added IM121 after IM61

<string>IM41.0055.B08</string>

<string>IM42.0071.B03</string>

<string>IM51.0090.B03</string>

<string>IM52.0090.B03</string>

<string>IM61.0093.B01</string>

<string>IM121.0047.B1F</string>

<string>MP11.005C.B04</string>

<string>MB11.0061.B03</string>

<string>MBP11.0055.B08</string>

<string>MBP12.0061.B03</string>

<string>MM11.0055.B08</string>

Scroll to the USBBootSupportedModels -> Added my model in the right logical order, but notice I did not add IM122 I added IM120

<string>IM120</string>

<string>IM130</string>

<string>MM50</string>

<string>MP60</string>

<string>MB80</string>

<string>MBP90</string>

<string>MBA40</string>

File Save -> Open Bootcamp if all worked you should now see 3 options on the second screen.

Hope this helps!
