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

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

I'm a noob, so forgive me if I'm being very ignorant here, but how on earth could that be a good idea? It sounds like "in order to see if I've installed these airbags correctly I shall now crash head first into this concrete bridge foundation at max speed"?

I'm assuming it's a fresh install, so nothing of value was lost if the restore failed. But also I've heard attempting to delete things in /sys and /dev can brick your computer. So it's not a great idea.

I'm not so sure your analogy works. Unless you are testing to see how fast you can bring a new test dummy into production. Or you are testing to see how fast you can install new airbags with blemishes and all.

It gave me a reason to finally run the command that by recursively deleting everything.

It sounded like you were testing the (one and only) backup in a live environment is all.

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