Hi everyone. I want to install windows 7 on my iMac 24'' (mid 2008) but my optical disc drive is broken. I tried to install it with an USB flashdrive, but the system don't recognize it as a bootable device. I have the windows 7 ISO, vmware fusion, refit (i searched on the interet for the solution but i couldn't find any). thanks for help !
iMac, Mac OS X (10.6.8)
***Solution That Worked for ME***
I had a similiar problem where I wanted to install windows on a macbook pro (early 2009) that had a broken optical drive, using a bootable windows 7 USB, but the mac wouldn't recognize the USB because it only checks in the optical drive.
Solution:
1. Download the Windows 7 ISO file here: http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325 /
2. Use Windows 7 USB DVD Download tool (found here http://www.microsoftstore.com/store/msusa/html/pbPage.Help_Win7_usbdvd_dwnTool to make a bootable windows 7 USB. (this has to be done on an exisiting windows machine, but there are googable solutions to do this process using just a mac)
3. Also transfer a copy of the ISO file to the mac
4. Use Daemon Tools Lite (free, found here: http://www.daemon-tools.cc/products/dtLite) to mount the ISO file thats on your mac. (open daemon tools, click quick mount, click the iso file, very easy!) This tricks bootcamp into thinking that a windows 7 install disk is inserted.
5. Run Boot Camp, I chose to skip downloading the drivers and did that separately here: http://support.apple.com/kb/ht5634 by cliking on the macbook pro model and then the number in the grid to download the boot camp drivers to a separete usb. Once windows was installed, it was easy to open the USB and run bootcamp settup.
**THE TRICK**
6. When the computer restarts after bootcamp finishes, insert the bootable windows 7 USB into the mac when the screen is black, and then hold down the C key as soon as you hear the mac turning on sound. This command tells the mac to boot from USB.
I did not find any discussions of simply pressing the C key to boot from USB in similiar threads, and people just said that you need the disk if your mac has an optical drive. I finally found this trick out here: http://support.apple.com/kb/ht1533
The windows installation should now be running, and all thats left now is to choose the Bootcamp partition when it asks, and to click on it, click drive options, click format, and then click next to continue on with the installation.
Hope this helps anybody that had the same problem as me, I did a lot of googling!

Thank you in advance
Do you get any error messages?
Hey loner,
Thanks for the quick response. I havent gotten any errors. When i boot it goes to thr mac os bootloader screen (i geuss) and aftet a while it goes to a black screen with a cursor blinking. I jusy realised that i havent ried to type, i assumwe that windows setup would start automatically. Do i assume right?
The black screen with blinking cursor indicates that OS X has handed control to the Windows side. It should bring up the Windows Installer without you having to type anything. If you power down your Mac, power it back up and hold Alt/Option, what selections do you see?
It only shows the os x and network connection thingy.
sudo bless --folder /Volumes/BOOTCAMP --legacy --legacydrivehint disk0s4 --setBoot --verbose
Try this and see if it will boot from the BOOTCAMP volume.
output:
EFI found at IODeviceTree:/efi
Mount point for /Volumes/BOOTCAMP is /Volumes/BOOTCAMP
Common mount point of '/Volumes/BOOTCAMP' and '' is /Volumes/BOOTCAMP
No BootX creation requested
No boot.efi creation requested
Can't statfs /Volumes/BOOTCAMP
Boot didn't work, also nothing new in "alt" screen. Just a blinking cursor in an endless black void
Can you post the output of

Can you see files in Finder on this Bootcamp volume?
yes I put in the windows 8.1 decompressed and I tried with a copy of the USB tool
1. Can you provide a bit more detail on what you mean by "Decompressed W8.1"?
2. Is the USB tool what is created by Microsoft's Media Creation Tool?
3. Is it possible to post a screen shot of the NTFS partition from Finder? If you right-click on the Bootcamp partition on your desktop and click on Get Info, what does it show? Remove any personal information as you see fit.
Of course I can
1. I downloaded an iso of windows 8.1, mounted it and copied the files to the bootcamp partition. I also made a windows 8.1 usb tool with BCA and copied its contents to the bootcamp partition when the aforementioned trick didn't work.
2. no via BCA
3. yes! 🙂
3. yes 🙂
For item #3, unless you have the $WinPEDriver$ directory on the NTFS partition, you will be using generic drivers. The larger problem is Tuxera. Can you uninstall Tuxera temporarily and check if the Bootcamp volume shows up in System Preferences -> Startup Disk?
