«Wrong EFI loader signature» boot message — but it boots anyway

Post by retry3 » Sun Dec 06, 2020 10:42 pm

I am running fossapup64 off live CD.
During boot up, right after it says it is loading initrd, comes a starred statement «Wrong EFI loader signature».
the boot up continues and I eventually get into Fossapup64, OK as far as I can tell.

Should I be concerned about the Wrong Signature message ?
I am old and slow and a permanent beginner.
Thanks

@retry3 — consensus from internet is «if it works, don’t worry». I last saw this message when booting recent puppies on non-uefi hardware, even though I used a non-uefi bootloader (grub4dos). For uefi machines, having secure boot & tpm disabled in bios & using syslinux bootloader instead of grub, I do not get this message.

Just ignore it. Unless you’re specifically booting using secure methods/signatures. For BIOS . etc. type boots (which I boot myself and see the same message) no efi signature will even exist so the system is just flagging that the signature was wrong.

Yup, I’ll confirm that. The set-up I use is like many here; a UEFI system, but booting in ‘legacy’ mode. I get the same message, too. but since Fossapup boots and runs just fine, as Ruffers says, «if it works, why worry?»

What is the computer?
Make and model?

@Mikewalsh —
Thanks, that sort of clears things up a little more.

@bigpup — Sorry for not including full info, trying to save on keystrokes;

Intel(R) Core(TM) 2 Duo CPU
Ram 4.00 GB

Bought 2018 refurbished
Is there a Puppy command that will show the system info the same way as Windows does ?

Yes,
Menu -> System -> Pup-Sysinfo and then Sys-Specs -> Base Report

BIOS — LENOVO 5CKT54AUS, 9/7/2009

If this is a UEFI bios and it is that old.
They were still trying to get all the bugs out of UEFI and still working on exactly what it would or would not do.
There really was no set way for it to work, what it would look for, how it would react, etc.
A lot of it was up to the computer manufactures and how they wanted their UEFI to work.

The last few years everyone has settled on what UEFI would do and how it would work.

I wonder if that warning is just telling you that something other than Windows is trying to be used.
Puppy Linux is not providing the expected signature that Windows will provide.

As they say.
If it is not broken!
Do not try to fix it.

funny none of the UEFI computers I have give that message.
But they are using much newer versions of UEFI.
All of mine are personal computers or ones I built from a bunch of after market parts.

The ThinkCentre is a line of business-oriented desktop computers

they probably have UEFI access restrictions set tighter than a personal computer will have.

Thanks rockedge & bigpup, your comments help clarify things.

I never try to «fix» things like that, I was just afraid it was a warning that a disaster was building up.

I recently had this error message. It turned out that signatures from the previously installed version of Linux Mint remained in the UEFI boot settings. I deleted these items in UEFI and cleaned up the /EFI folder on the hard drive. After that, the error message went away.

Fossapup OS, Ryzen 5 3600 CPU, 64 GB RAM, GeForce GTX 1050 Ti 4 GB, Sound Blaster Audigy Rx with amplifier + Yamaha speakers for loud sound, USB Sound Blaster X-Fi Surround 5.1 Pro V3 + headphones for quiet sound.

Not able to boot into Chrome OS even after installation done by Linux terminal.

My System Configuration:

CPU: Core 2 duo E7500
RAM: 4gb DD3

My PC doesn’t support UEFI. I tried by using tutorial with the mbr support material but couldn’t boot into chromeOS.

Note: I got the «ChromeOS installed» message in the Linux mint terminal after completing all the steps as per the guide.

I have attached a video and some photos which tells about bootloop going through with the EFI loader signature error.

If you need any other information regarding this please inform

Sorry for the video to be faster than it was in real but couldn’t get that under required size without it.
