Upgrading from El Capitan to High Sierra I get Stop Sign from the boot disk

[sdancer75]

Pretty new to macx86. I installed El Capitan and then I upgraded to High Sierra. Unfortunately booting from the disk I get the Stop Sign (no text at all) and then PC goes to sleep mode.

Error I get in verbose mode is : This version of MacOS X is not supported on this platform. Reason : Mac - F42C88C8

Booting from an external USB disk and then selecting the MacOS HD Disk, it boots fine. The boot app is clover.

Any help is highly appreciated.

I get the Stop Sign

It's not a stop sign :

no text at all

Boot in verbose mode.

Most likely a USB problem - Search for 'prohibitory symbol' or 'still waiting for root device'.

I just did and the error is This version of MacOS X is not supported on this platform. Reason : Mac - F42C88C8

So the question is how can I change the platform inside clover?

Try Clover Configurator.
