From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Debian 12 not booting, but OS intact (lemmy.blahaj.zone)

So I want to install Debian 12 on my machine, and the installer just -kind of- worked. I couldn't use the live USB with all the cool UI stuff, I had to use the normal installer without the whole DE. But that worked. I have Debian 12 now on my SSD. I can even access it through the "rescue mode" using the Debian USB as shown in the first picture. But actually booting from it is a whole other story. I can select it as a boot option, but it says that this drive doesn't have an operating system on it. It can be seen in the second picture.

Has anyone an idea on what could be going on here?

Are you sure you installed the bootloader?

UPDATE:

I got it working by messing around in the rescue mode. I selected some option which fiddles with the EFI boot and makes it accessible to the boot loader. So that's cool. Now everything works.

You should edit the post instead

Looks like you need to configure your UEFI boot entry for Debian.

Classic "I wiped my ESP." Reinstall GRUB or whatever bootloader Debian uses from a chroot.

This might be fixable by reinstalling the bootloader. On boot the motherboard firmware is supposed to locate and execute the bootloader on the SSD. The error here looks like it's coming from the firmware having failed to do that for some reason.

Since you can get into rescue mode these instructions should work: https://wiki.debian.org/GrubEFIReinstall

That's always the first thing I try in this kind of situation.

Maybe there could be an issue with secure boot. But I'm not sure if that's something people need to worry about these days. https://wiki.debian.org/SecureBoot

There could be some sort of problem on the firmware side. HP has steps for troubleshooting this error here: https://support.hp.com/us-en/document/ish_3053911-2842957-16
