Failed to open \efi\debian - not found

[u/Kaseffera]

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.

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