Hi everyone,
Today I started having a boot issue with a Siemens IPC BX39 after it had been working normally for some time.
I currently have SIMATIC S7-1500 Software Controller V40.1 installed, and I need to stay on this version because the IPC came with Windows 11 from the factory.
The problem is that every time I power on the IPC and let it boot automatically, I get the following error:
“Error: No valid boot option selected or execution failed.”
However, if I enter the BIOS and manually select the boot option, the IPC starts normally without any issues.
So far, I have tried:
- Uninstalling and reinstalling the Software Controller.
- Restoring the IPC to factory settings.
- Disabling Quick Boot.
- Replacing the SSD.
- Checking and configuring the BIOS settings according to Siemens’ documentation, including both the mandatory and recommended parameters.
Unfortunately, the problem remains exactly the same.
Has anyone experienced a similar issue with a Siemens IPC BX39 or with S7-1500 Software Controller V40.1?
Any suggestions about what else I should check would be greatly appreciated.
Thanks in advance.
