I'm running into some problems with Kubuntu all of a sudden. Yesterday the computer was running poorly, and after a restart it came up with:
... and then dropped me into the BusyBox built-in shell, which I've never been in before.
error: hd0 out of disk
press any key to continue...
I heard that the "out of disk" error can be a problem with grub, so I booted from an image and was going to see if that was the problem. However, my attempt to mount the drive yields this:
dmesg then yields:
kubuntu@kubuntu:~$ sudo mount /dev/sda1 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I'm at a loss. I suspect an issue with the drive; it shows up in the BIOS at full size, but it won't mount from its slot or if connected via USB (RunCore SSDs have a Micro socket built in). Anyone have any ideas?
kubuntu@kubuntu:~$ dmesg | tail

In case you need the info, it's a Dell Mini 9 with a 32GB RunCore SSD and 2GB of memory.
