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)

This is because I asked you to run setup.exe. 😉.

Try the run the individual exe files in a Admin command window.

Do you have the ability to test W7 32-bit and 4.0.4033?

No, I can't install Win7 32bit, and I don't say a mistake, I need to use 64bit on my version of iMac

Based on Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support, the 20-in Early 2009 iMac only supports W7 32-bit. This is part of the reason for driver issues.

I assume you mean W7 64-bti in the above statement. Can you try W7 32-bit and test?
