Hello
I have a new Dell Inspiron 17 5767 i5 / 16GB / 250SSD R7 FHD purchased without a system.
When booting from the Windows 7 CD, I get this message:
"Operating system loader has no signature. Incompatible with SecureBoot. All bootable devices failed Secure Boot verification."
What could be the reason for this and how can you remedy it?
Thanks for your help and best regards.
