Accidentally Deleted /boot/ (Debian) (links.hackliberty.org)

Hi all,

I'm having a bad day and did something colossally stupid, deleting everything from /boot/.

The system is still running. What do you think my best course of action is?

My current idea is to create a timeshift backup, reinstall debian from USB, then restore from backup in timeshift

If this won't work or you have a better idea I would really appreciate your advice.

Thanks in advance

Your system would continue to work as long as you don't turn it off. So no matter what you do, keep it on until you restored your /boot

Recovering it should be straightforward, assuming you didn't put custom files directly to /boot.

Just reinstall the linux kernels using apt. Then manually run grub-install with appropriate parameters. Finally, run update-grub or grub-mkconfig to recreate the grub config.

If the system is turned off, you can use live USB and chroot to it to properly install the kernel packages.

I've only ever used grub with bios/mbr or a BIOS/gpt (with grub bios partition).

No clue about efi/uefi.

This is the simplest method I can think of.

The arch wiki, however, is, as always, a great source of info:

**Linux is amazing in it's ability to keep working even when you accidentally all the things.

I once sudo apt removed mint-x-icons or something which, for whatever reason, also needed to remove cinnamon. As in cinnamon the entire DE.

I realised what I had done as I watched the terminal.
#%&@! panic.
...
reinstalled.
joy.

Annoyingly so. I once made a backup. Then to confirm it would restore the system, I deleted everything on root path. as in /

It did as told.

OK let's reboot and verify system.

Sudo reboot

Command not found

sudo shutdown

Command not found

But it sat there with a blinking cursor on the terminal

Not to victim blame but you did put in --no-preserve-root. You had to read those instructions.😄
