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)

Please download drivers for your specific iMac from Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support. You are missing the nVidia Coprocessor driver. Run setup.exe from the Bootcamp folder. On W10, you need to run the specific driver executable with Administrative privileges and computability set to W7.

I have ever installed the bootcamp driver.

if i follow your link i need to download the driver for Imac late 2009, so it is bootcamp 4.0.4033.

But when i run setup file (with windows 7 compatibility) i have a message "Boot Camp x64 is unsupported on this computer model"

So to happen to install driver, i have followed the steps of this link http://tsentas.net/bootcamp-x64-unsupported/http://

where bootcamp 5.0.5033 is used...

After the driver was installed, was the Coprocessor recognized and installed properly?
