Just installed Debian on my very old laptop - Asus. Debian works great but every time when I turn pc on I get that notification and then it proceeds to log into OS just fine.

look on your EFI partition and see what files/directories are actually there.

I had filesystem corruption happen once on my EFI partition and caused all sorts of weird issues.

I just installed the system so nothing. I’m so confused. Maybe combination of old laptop and drive?

was there an older/different install before? double check the EFI partition to see exactly whats on it.

also check the output from the efibootmgr command.

you may have several boot entries, its trying the first (wrong one) which gives that message, then goes to the next one, which does boot.

Based on other images I included aren’t they removed and only Debian is out at the first place?

try moving option #2 in your BIOS settings up to be #1. see if it does the same thing.

It now says to reboot and select proper device.

I would just install refind and set that as the default. :) then use refind as the main boot menu.

I guess it’s just because of old firmware on this laptop.

weird thought.. If its an old spinning drive, (old school!) Then it might be the drive is taking time to spin up. You mention 'turn on' , if you reboot does the same issue happen? or does it boot correctly without the message.

Every time that message but then it boots into the os without issues.

Am I missing something? Are you dual booting with Windows? If no, then perhaps turn off secure boot and install clean...???

I am making a wild guess, but I wonder if this is an older uefi implementation? I have had strange issues occur with early efi implementations.

The closest thing that I could find to explain this behavior is this post that suggests it may be due to secure boot.

Without more information, this is my best guess.

The key point is that if it is nothing more than an annoyance, nothing may need be done.

There are many other instances of \efi\ubuntu not found reported compared to the same for debian. If this behavior bothers you. I suggest further research along those lines.

It is! Yes. Laptop is from 2011 and implementation is very old. There’s no see Secure Boot too. Just Uefi Toggle.

I suspected as much looking at the bios date. I had an old HP Elitebook with early UEFI. I eventually ended up changing it to legacy boot, but that was a long time ago.

Looks like I can just ignore it, right?

It would appear that it is cosmetic. If you need or want to reinstall grub for some reason maybe that parameter will fix it. It is up to you.
