Hi, I am trying to install SLES 12/SP1 (or 11/4) on a PC with AMD A4-4000 APU on a Gigabyte ULTRA DURABLE motherboard.

On the initial installation menu with "e" emac like or "c" grub command line options I try Installation.

Which brings up following messages and triggers then a system reboot.

Loading Kernel ...
Loading Initial Ramdisk ...

Additional 12/SP1 comes before the Installation menu with an message
"error PNG not a PNG file.
"press any key to continue

Anybody who can advice how to install?

Thanks and kind regards,
Axel
