Bootcamp without Optical disc drive

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!

You can re-run the Gdisk steps and do them correctly and test.

Hey, for the people out there who are having trouble with this subject, I'll give you my solution. I have an early 2006 iMac that I installed bootcamp on by creating a bootable usb on a windows computer and holding down the c key when my mac turned on. One day, that didn't work. It really sucked. I has been months now, but from other forums, I got this figured out. First, download this file from my dropbox https://www.dropbox.com/s/rekxut9ogimv7z6/refind-bin-0.8.7.zip?dl=0 Then, unzip it. Then, open Terminal and drag the file to the terminal window until a green plus appears and release. Then, hit enter. It will begin installation. After that, reboot your Mac and the bootmanager will show up!

This is what I got from my terminal window. Seems I can't go any further?

If the output of

shows a valid NTFS header, and you can see files in the Bootcamp volume, then you will needs Windows Startup repair.


The value of 'N' in the command must point to the disk which has your Windows partition. You can find it using diskutil list command in Terminal.

Can you see files in Finder on this Bootcamp volume?

Oct 20, 2015 4:46 PM in response to Paul_mac_live

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.
