So I'm using a Live disk after I screwed up my linux partition last night. The strange part is that usually I a better explanation to what happen. I've been running crunchbang for a few months now without any problems.
last night I updated/upgraded my system. No errors but it was acting extremely odd afterward. Finally I had to hard reboot. It loaded in to grub rescue, but there was no options. I realize then, that the reason why commands weren't working is because something had happened to my boot partition.
I've been trying to examine it. I can't mount it.
fdisk recognizes it as a linux partition, gparted doesn't know what type of filesystem it is. I was just about to format and reinstall when I got to wondering if there was anything actually on it still on it.
when I run:
sudo dd if=/dev/sda4 bs=512|hexdump -C |less
There appears to be something of a partition table, but I don't exactly know what I am looking for.
Has anyone ever seen this?
What I was wondering is, how unique is one MBR bootstrap code area from another? If I were to make another ext4 drive and dd the first 440 bytes to my screwed up drive is it possible that I could at least make it mountable?
