I have an older desktop computer that I hadn't used in a few years because I hadn't had a land line. Last night a booted it up and connected it to my land line and it worked great.
Before I went to bed, I set it up to upgrade from 8.4 (told you I hadn't used it in a while) to 9.1. I was going to just slowly upgrade it to the current level.
In the morning it was frozen, so I shut it down. Probably a mistake. When I tried to reboot it, it got as far as loading grub, then gave me the following message:
Starting up...
Mount: Mounting none on /dev failed: no such device
udevd [866]: error getting socket: invalid argument
error initializing netlink socket
udevd [866]: error initializing netlink socket
libudev: udev_monitor_new_from_netlink: error getting socket: invalid argument
segmentation fault
Gave up waiting for root device. Common problems:
-boot args (cat/proc/cmdline)
-check root delay (did the system wait long enough?)
-check root (Did the system wait for the right device?)
-missing modules (cat/proc/modules;ls/dev)
Alert!

And then I can't do anything, including enter help. This all seems bad.
It's been a while since I've worked with Linux, so I really don't know what to do. Is my hard drive toast? Can I at least save my files? Can I fix it?
