Not sure if this is the right place to ask, I couldn't find anything about that on Google, I'm not really sure what to search for anyway.
We had a thunderstorm last week and power went out, I am not able to get past grub since then. I have an unknown file system error when i try to get into debian. I can enter the grub commabd line(not grub-rescue), but if I type ls it just outputs error unknown file system again instead of listing drives/partitions. The bios can detect my boot drive. And I think i can reinstall an os on it as it gets detected by a live usb too. How can I solve this without reinstalling and reconfiguring everything? I don't know if this is relevant but my system is an old Hp z800, boot drive is an hp sata ssd and the OS is proxmox 7.1.something. I know this is for bug reports, but I really don't know where else to turn to. Thank you for your time.
