Hi, experts. Immediately after the installation of the SUSE Enterprise Server Operating System, it does not start and remains on this screen. ![](https://forums.suse.com/uploads/editor/wn/3518zmai5g6o.png) I modified the list of parameters (I added a few enter) and sometimes it enters the System. Some Technical details: O.S: SUSE Linux Enterprise Server for SAP Applications Processor: Intel Core i5 6th Gen RAM: 16 GB Hard Disk: SSD 960 GB What could this be? Thanks in advance, ---

So your system is set to UEFI boot in the BIOS? = Yes Disk was set to GPT type? = Yes If you boot and get to the boot menu, can you select the efi file to boot from? = Is this done by editing the parameters? ---

Hi No, pressing a key eg F12, F10 etc to see the BIOS boot menu… Can you boot from the install media, select rescue and at the prompt post the output from; ```auto lsblk efibootmgr -v ``` ---

@David yes third party non signed modules does that 😉 I use qemu since it’s part of the distribution, all my qemu machines use secure boot (well tianocore).
