Can't install windows 7

[stigzy]

Hi!

I am trying to install windows 7 on my 27" mid 2011 iMac. I have changed the 1TB HDD with 2x 250GB SSD drives instead. And now i cant install windows 7.

When my iMac restarts to get to the windows 7 installation from either my USB stick or CD with windows on it, it says: "No bootable device -- insert boot disk and press any key". I have googled like crazy, and tried different solutions, but with no luck. I have changed the info.plist in different ways, tried installing Windows on both my SSD in my iMac, but nothing work.

Can anyone help me with a possible solution?

Are you sure the drive is properly connected? Have you formatted it to be recognized?

I am pretty sure my drive is connected correct. I have installed windows many times, so in my opinion, it should work the way i do it. Both SSD work as they should and the same does my CD drive.
