Can´t boot True image on HP Pavilion 6 with UEFI

This works for me with a Lenovo 8.1. With your rescue media attached: http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/

Maybe I should have added that I`m trying tu use True image bootable media DVD.

Or is your link useful for that too?

Yes, those instructions can apply to any boot media. 

I don't believe Acronis provides a signature or at least my computer doesn't think so.

I neglected to remind you that your boot device (your DVD drive) must be listed as the first boot device in your BIOS (ahead of Windows Boot Manager).

On my computer when I insert an Acronis boot flash drive and USB HDD is set as the first boot device, I will get a message (see attachment) that my PC needs to be repaired. This allows me the option to press F8 which brings me to the screen where I can bypass the signature requirement. This accomplishes the same as the above procedure. Neither are very elegant.

Ok will try it tomorrow,and Ive made an bootable USB stick to try to..

Today I tried the bootable USB stick and it workt,it booted from it,so problem solved Thanks!
