Q: Bootcamp NO BOOTABLE DEVICE

Hy community,

 

To begin, sorry for my english, i'am a frenche user

Since three days i try to install Windows 7 64bits on my iMac 20" inch (early 2009) on Yosomite 10.10.2, but it doesn't work. I have a superdrive but every DVD i'm putting is ejecting or the wrinting failed.

 

So, I have modified the info.plist. I have tried two methods to attempt to erase the "No bootable device" after bootcamp process.

I'm using an 2.0 USB Kingston 32Gb DTSE9. The other usb i have is an 3.0 USb and I read this type of USB is not accepted by the bootcamp process.

 

First: run bootcamp, check the three options (iso, drivers, installed W7). The bootcamp partition is great created, the iMac reboot, but i have the "No bootable device" on black screen.

I need to press ALT on the reeboot to select OSX partition.

 

Second: run bootcamp, check ISO file, unckecked drivers and installed W7. The bootcamp partition is great created.

I ran a second time bootcamp and I ckeck only Installed W7, the iMac reboot, same message.

 

Please, i need you for my problem.

I have read some similar topic but I don't find the good answer for resolve my problem.

 

Thanks a lot.

iMac (20-inch Early 2009), OS X Yosemite (10.10.2)

    An external optical drive on your Mac will not work.

    The internal Optical drive method is the simplest. You can try the following methods in lieu of the Optical drive method.

     

    1. Bootcamp without Optical disc drive

    2. http://forums.macrumors.com/showthread.php?p=20584499#post20584499

     

    These may or may not work. Please backup OS X so you can wipe you Mac and start from a clean Mac, if necessary.

    First, make sure you have a backup of OS X. Second, back up Windows 7. Please use Gdisk 'b' command to create a backup of your GPT/MBR and store it externally, and then try the W7-to-W10 upgrade.

    do you have a link to follow your recommandation?

    because I don't know Gdisk command and when a check out on google i have a lot of results.

     

    The back up of OSX and Win7 must be done since OSX, that' right?

    1. Backup OSX using Time Machine.

    2. Backup Windows to a separate external disk formatted as NTFS.

    3. Download GPT Fdisk from http://sourceforge.net/projects/gptfdisk/ and install it.

    If you GPT is ever corrupted, you can boot from a Linux Live CD and restore this backup to get your GPT partition layout restored.

    Yes, if Apple drivers are properly installed, it should allow the Apple Keyboard (USB and BT, both) to change the screen brightness and brightness. Can you check Device Manager for any unknown devices or with yellow triangle and exclamation marks?
