Did I break my installation?

[proxwolfe]

I am afraid I may have rendered my system unbootable (as per this thread: https://forum.proxmox.com/threads/sometimes-it-is-just-maddening.71623/).

This is what I did: I wanted to amend the kernel command line in order to allow pci passthrough.

I found this: https://localhost:8006/pve-docs/chapter-qm.html#qm_pci_passthrough

and followed it to this: https://localhost:8006/pve-docs/chapter-sysadmin.html#sysboot_edit_kernel_cmdline

I don't know whether proxmox boots via grub or systemd-boot. It looked like both is possible so I went with the one I know: grub

I followed this through:
"Grub
The kernel commandline needs to be placed in the variable GRUB_CMDLINE_LINUX_DEFAULT in the file /etc/default/grub. Running update-grub appends its content to all linux entries in /boot/grub/grub.cfg."

and then happened to find a thread (above) that now makes me fear my system won't boot up again.

Assuming this is what is going to happen, what do I need to do to rectify the situation?

Thanks

1. do not reboot until you understand what you did
2. /boot/efi should be mounted to see if it contains an entry for grub or loader now you know
3. if it reads grub and you know grub, you should be fine
4. if it read loader and contains loader.conf you are using systemd-boot, use pve-efiboot-mgr
5. if it contains both, you have work to do

Thanks for your help!

I checked and only found grub. Proxmox came back after the reboot. All good now.
