[Linux Mint] Mint 12 Won't Boot after failed backintime backup

view story

http://ubuntuforums.org – Hello everyone, This evening I was doing a backup with backintime on a computer with limited HDD space when a dialog popped up saying I had less than 1 GB of space left. I checked this in GParted, and sure enough, the backup was taking up all the remaining space. I tried to cut the backup short by deleting the directory where the backups would be saved. This seemed to work - until I rebooted. It gave me a black screen with text on it that complained about a broken pipe among other things, and boot would hang. Does anyone know what happened and/or how to fix it? Thanks! (Hardware)
