Hello,

 

recently I started seeing a warning each time I boot up my laptop saying that "HP Sure start detected an unathorized change to the Secure Boot keys." See

I am not sure what caused this I do recall doing a system upgrade on the OS (Ubuntu) not long before this started happening.

 

Since this warning persists, I figured I'd upgrade the bios. I've downloaded sp107399.exe  

Which seems to be the latest BIOS for this specifc laptop. I've put the respective .BIN file into the EFI folder so that the structure looks like this

 


HP/BIOS/New/N75_0149.bin
HP/BIOS/Previous/N75_0149.bin

Similarly, I've put the .bin files on a USB key with the same file structure as above. When restarting the OS I coulnd not get the update process to work. Specifically, the BIOS says it cannot find any bios upgrade files. See

At this point I don't know what else to do. I've tried googling for this same problem and tested the suggested variants, but nothing seem to work. As a final note here is the system information page from the BIOS

Can someone help me upgrading the bios? Also, what could be causing this secure boot warning? Any ideas?
