Hello,

I have a problem to boot on the Windows Server Technical Preview iso.

I have an error "Boot Failed. EFI SCSI Device".

If I replace the ISO by Windows Server 2012 R2, it works.

Any idea?

Thank you.

Florent

Hi,
 
According to your description, my understanding is that boot on Windows Server Technical Preview iso prompts error "Boot Failed. EFI SCSI Device", while successfully boot on Windows Server 2012 R2.

I am wondering if you use hyper-v to create virtual machine, on just boot on physical machine.

If the former is the case, I recommend you to choose the Gen 1 VM(Gen 2 VM supports Win8/Win2012 or later) and try again.

Besides, make sure you have a key held down when it gets to this point Press any key to boot from CD or DVD.

Best Regards,
Eve Wang

If you are using the Technical Preview 1 media then the certificates on the boot files expired on 1st May 2015.

You either need to download Technical Preview 2 or set your system clock to before 1st May 2015 to boot.

It's exactly what I think, and I just tried with the Tech Preview 2 and it works.

Thank you for your help.
