El Capitan Boot disk not showing!

[flyman]

Hi Everyone,

I've created 2 different versions of an El Capitan boot drive using Terminal and on Apples advice Diskmaker X (1 on an 8gb usb stick and another on an internal HD) however neither of which will work for me!

I've tried choosing system preferences but neither boot disk will show up to choose and neither show if I restart holding down the ALT key.

To give you some background I've replaced my video card for an unsuported Nvidia GTX 670 which has no EFI and hence no grey start up screen so could this be the cause of my problem?

I should also mention that I cannot get into recovery mode using cmd-R.

Hope that makes some sense and many thanks in advance...

Sounds like you've answered your own question...

Have you tried creating a usb installer boot up and seeing if it will load from Start up Disk in System preferences?
It sure doesnt want to for me!
I was under the impression it was only while holding down the alt key that you're not able to see the disk?
