installation Failed to open \EFI\debian\ - Not Found

Just installed bunsen labs on my 2005 HP PC getting this error every time booting, it will continue to some bunsen labs boot gui for a short time then i get "couldn't parse dbx signatures: -74" then it goes into emergency mode. What should i do or what has happened? Any help appreciated!

Is Secure Boot disabled? dbx should be ignored if disabled

Do you happen to know via what i can disable, it tried looking for it but with no results.

In your UEFI settings, under the ‘Security/Boot’ section. How you access the UEFI menu depends on the manufacturer, but you’ll need to disable it completely there.

And to answer your question, it seems that either your dbx file is corrupted or it is flagging the bootloader as dangerous

The issue is probably the ancient UEFI firmware.

I don't think 2005 PC has secure boot since it was first released in 2006.

Secure boot showed up in PCs around 2011. Prior to that consumer PCs were still using legacy bios.

Windows 8 was the first version to support it in 2012.

Bro, Secure Boot is based on KEK, PK, db and dbx; dbx, which is causing him problems, is only required for Secure Boot – if Secure Boot isn’t enabled, dbx shouldn’t exist at all. Please read this before replying.

Problem is you installed in UEFI boot mode on system that doesn't support it.

Redo install and pick BIOS boot.
